The first step is to check the power supply. Pay attention to the monitor - if the LED is lit on it, then at least power is supplied to it. In this case, first check the computer's power supply switch (on the back of the PSU). If it is disabled, enable it and test your PC again. A new shutdown will indicate the presence of a short circuit. In this case, turn off all peripherals, including the mouse and keyboard. Turn on the PC again - if the download goes, look for a short circuit in the periphery. The mouse and keyboard can be checked by replacement.
Many motherboards have a power indicator - LED. By removing the side panel from the system unit, you can see if the LED is lit. If yes, but the PC does not turn on, this indicates a malfunction of the motherboard or other serious defects. In this case, it is recommended to contact the service center for help.
Computer turns on but won't boot
The reason may be a malfunction of components - for example, RAM, or a malfunction of the OS bootloader. The computer usually reports a malfunction of the components with a tone signal, its decoding can be found on the network. If the download is not in progress, first try to correct the situation by pressing the F8 key when starting the PC. A menu window will appear, in it you should select the item "Load Last Known Good Configuration". In most cases, the PC then boots up successfully.
If you are unable to boot your PC, you can try to restore it using the installation disk. The easiest way to do this is for Windows 7 - after starting the installation of the OS, select the restore item, then in the list that appears, select fix boot problems. After that, the computer should boot. To restore Windows XP, you will have to manually enter some commands, a detailed description of this procedure is available on the network.
To check, you can try booting your computer from the Live CD included with many Windows installation builds. If the OS boots, you will be sure that the hard drive and other components are working, the problem should be looked for in the bootloader or the OS itself - for example, it can be damaged by viruses.
Video card and monitor failure
Sometimes the cause of the black screen is a malfunction of the video card, it can be checked by replacing it. If your PC has an integrated graphics card, you can connect a monitor to it. The appearance of the image will clearly indicate a malfunction of the main video adapter.
If the computer has booted up and the monitor power indicator is on, but there is no image, shine a flashlight on the screen - you may see a very faint image. In such a situation, everything speaks of failure
A black screen when booting up a computer or laptop indicates a serious software or hardware problem. This may cause the fan on the CPU cooling system to spin and the HDD loading indicator to light up. A significant amount of time and nervous energy is usually spent on solving such problems. In this article, we will talk about the causes of the failure and how to fix them.
There are several types of black screens, and they all appear under different circumstances. Below is a list with explanations:
Option 1: Blank screen with cursor
As mentioned above, such a screen tells us that the GUI of the operating system is not loading. The Explorer.exe file is responsible for this ( "Conductor"). Startup error "Explorer" may occur as a result of its blocking by viruses or antiviruses (in pirated copies of Windows, this is quite possible - there have been cases), as well as due to banal damage by the same malware, user hands, or incorrect updates.
You can do the following in this situation:
Option 2: Boot Disk
Such an error occurs due to a software failure or a malfunction of the media itself or the port to which it is connected. Also, this can happen due to a violation of the boot order in the BIOS, damage to boot files or sectors. All these factors lead to the fact that the system hard drive simply does not turn on.
The following steps will help resolve the issue:
- System restore with pre-boot attempt in "Safe Mode". This method is suitable in case of failure of drivers and other programs.
- Checking the list of devices in the BIOS and their boot order. Some user actions can lead to violation of the media queue and even removal of the desired disk from the list.
- Checking the health of the "hard" on which the bootable operating system is located.
The information provided in the article above is suitable not only for Windows XP, but also for other OS versions.
Option 3: Recovery Screen
This screen appears when the system is unable to boot on its own. The reason for this may be a failure, an unexpected power outage, or incorrect actions to update, restore, or change the system files responsible for loading. It could also be a virus attack directed at these files. In a word, these problems are of a software nature.
First of all, try to boot the system in normal mode - there is such an item in the menu. If Windows does not start, then you will need to perform a series of actions, in order:
- Attempt to run Last Known Good Configuration if possible.
- If it doesn't work, then it's worth a try. "Safe mode", some programs, drivers or antivirus may be preventing the download. If the download was successful (or not so), then you need to perform a "rollback" or restore (see below).
- To start the recovery environment, select the appropriate menu item. If it is not there, you need to restart the computer and at the next boot, press the key F8. If after that the item does not appear, then only the installation disk or USB flash drive with Windows will help.
- When booting from the installation media, you must select the mode during the startup phase. "System Restore".
- The program will scan the disks for installed operating systems and, possibly, suggest making changes to the boot options. If this happens, then you need to press the button "Fix and restart".
- In the event that you are not prompted to automatically correct errors, you need to select the system in the list (most often it will be one) and click " Further".
- You can try to select the first item in the console - "Launch Recovery" and wait for the results, but in most cases this does not work (but worth a try).
- The second point is what we need. This function is responsible for finding restore points and rolling back the OS to previous states.
- The recovery utility will start, in which you need to click "Further".
- Here you need to determine after what actions the download failed. After that, select the appropriate restore point and click again "Further". Don't forget to check the box next to "Show more restore points"- this may give additional scope for choice.
- In the next window, click "Ready" and wait for the end of the process.
Unfortunately, this is all that can be done to restore system boot. Then only reinstallation will help. In order not to get into such a situation and not lose important files, make regular backups and create restore points before each installation of drivers and programs.

Conclusion
Thus, we have analyzed several options for the appearance of a black screen when loading the operating system. The success of the recovery in all cases depends on the severity of the problem and preventive actions, such as backups and restore points. Do not forget about the possibility of a virus attack, as well as remember about ways to protect against this kind of trouble.
Windows can be considered fully operational after the desktop and applications added to startup are loaded, until this moment the system may experience slight freezes. But it may also happen that at some stage an error will occur and Windows will not be able to fully boot. A typical example of this is the appearance of the so-called black screen of death or Black Screen.
It looks like this: the computer successfully passes the POST procedure, the system boots normally, but the desktop does not appear. Instead, the user, after loading Windows 7/10, sees a black screen with or without a mouse cursor. Another variation of the same problem is the appearance on a black screen of a window with the error "Cannot find the script file C: / Windows / un.vbs." This happens most often because the Explorer file responsible for the operation of the graphical shell of the system cannot start normally.
There may be several reasons for this, but usually it is either some kind of conflict in the operating system, or the consequences of viruses. The probability that the problem is caused by hardware problems, in particular, the failure of the video card, is small, otherwise the screen would be completely black, and neither the cursor nor the Windows logo would be on it. So, what to do if a black screen appears when loading Windows 7/10? In any case, do not make hasty decisions and do not rush to reinstall.
Delays after installing system updates
It has been noticed that sometimes the Black Screen appears immediately after installing cumulative or major Windows updates. This may be a temporary phenomenon, so you need to wait a bit. If the desktop does not appear within an hour or two, then this should be a cause for concern. Reboot the computer, but not with the Reset button, but through the Task Manager called by pressing Ctrl + Alt + Del.
Choose from its menu File - Create new task and run the command in the window that appears shutdown /r /t0.
If the black screen appears again when you start Windows 7/10, most likely you have become a victim of an error when installing updates or a bug in the updates themselves.
Error during update installation
The appearance of a black screen when loading Windows 7/10 can cause a failure during the installation of updates, for example, a sudden shutdown of the PC at the time of their installation. In addition, the updates themselves may contain bugs, which Microsoft itself admits. If you have every reason to believe that updates are the cause of the black screen, you need to remove them.
It's best to do this in safe mode. To enter it, press the F8 key during the reboot or run the command in the window for creating a new task msconfig.
After the system boots, go to the Control Panel, launch the "Add or Remove Programs" applet and click on the left side "View Installed Updates".
Uninstall the latest updates, then reboot.
Software conflict
Everything that has been said about updates is also true for video card drivers, screen adjustment programs, and the like. If the problem appeared after installing a new driver, then it must be removed, again booting into safe mode. The same goes for installed new programs.
Corruption of entries in the registry, the action of viruses
An even more common cause of the problem is the action of malware that overwrites the settings in the system registry that are responsible for launching the graphical shell. Then you will see a black screen when you start the computer in both boot modes. In this case, we do this. Using the Task Manager, open with the command regedit registry editor.
Expand branch:
HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NT/CurrentVersion/Winlogon
Pay attention to the parameter Shell. Its value must be explorer.exe and nothing more.
If something else is written, then you need to replace this entry with explorer.exe, otherwise the graphical shell will not start either in normal or in safe mode. If the Shell parameter does not exist at all, create it and set it to the specified value. At the same time, check the value of the parameter userinit, it should be C:/Windows/system32/userinit.exe.
Note: on 64-bit systems, you should also check the Shell and Userinit values in the key HKEY_LOCAL_MACHINE/SOFTWARE/Wow6432Node/Microsoft/Windows NT/CurrentVersion/Winlogon and fix them as shown above.
After making changes to the registry, reboot in normal mode. This method has proven to be effective in many cases of PC infection with viruses, it allows you to quickly eliminate the black screen and cursor when starting Windows 7/10, however, it does not solve the main task - removing malware from the system, so after loading the desktop, you must carefully check all the contents of the disk antivirus scanner.
Failure to install updates, viruses, incorrectly working video card drivers are the main reasons why the user sees a black screen and a cursor when the computer is turned on. In fact, there may be more. The appearance of the Black Screen was noted when changing the settings of the administrator account, after optimizing and cleaning Windows with third-party tweakers and cleaners.
It may not be possible for a novice user to determine what exactly causes an error. If the black screen with the cursor continues to appear when you start Windows 7/10, it is most reasonable to roll back to the system. Such points are automatically created by Windows when important changes are made to the system - installing programs, drivers, etc. It is best to use the installation disk with the distribution kit of your version of the system for these purposes.
Boot from such media, wait for the installation wizard window to appear, click "Next" and then "System Restore".
Then choose Troubleshooting - System Recovery.
Specify the target system and click on the "Next" window.
Select the desired point and follow the further instructions of the wizard.
Upon completion of the procedure, you will be prompted to restart your computer.
Rolling back to a restore point is an effective way to restore a damaged system to working order, but this is only possible if the appropriate protection feature is enabled in Windows settings. Its possibilities, however, are also limited. If the computer does not start, a horizontal cursor blinks on a black screen, or error messages appear at the top, all of these may indicate more serious problems. In such cases, the need to diagnose the hardware or restore the system partition from an exact copy (image) is not ruled out.
I don't want to be trite, but the so-called "black screen problem" when loading the operating system after turning on the computer is one of the most common problems that owners of both desktop computers and. An operating system that won't boot or a hard drive model doesn't really matter in diagnosing a problem. We will tell you about how to remove the black screen when loading Windows 7, 10 on a computer and laptop, the reasons for the failure.
This guide will be supplemented, so feel free to ask questions, as far as possible I will clarify the technical points and solve your black screen problems.
The most likely causes of a black screen on boot
First, you need to list the most common problems that cause a black screen, after which the operating system does not load (in other words, when you turn on the computer, a black screen). In rare cases, after loading, the user sees not only a black screen, but also a cursor. Causes:
- The conflict of the operating system, as a result of which it cannot load the graphical environment normally.
- Video driver problem (incompatibility with current operating system: e.g. Windows 10 or Windows 7 up to XP)
- Failed hard drive on a computer or laptop
- Windows is out of order and won't boot correctly (not in safe mode)
- Other hardware problems or system conflicts
- Windows can't wake up from sleep
Starting Windows in Safe Mode on a Computer
One of the most likely reasons why Windows or another operating system does not load is a system conflict, due to which the OS cannot work correctly after turning on the PC. This can be caused, for example, by the fact that the user installs an incompatible program or drivers that conflict with Windows, and when the laptop / PC is turned on, the conflict will make itself felt from an unpleasant side - in the form of a black screen. How to remove it?
Fortunately, the developers of Windows have provided the possibility of a safe login mode for the operating system, which is designed specifically to eliminate various compatibility problems. By entering safe mode, you can clean up all problems on your computer, resolve conflicts, and then boot Windows in normal mode.
So, to enter safe mode on the computer:
- Remove from the computer all media and devices that may affect the boot of Windows (flash drives, disks, etc.)
- Restart or turn on your computer, depending on its current state.
- To enter safe mode, hold down the F8 key during boot. If the PC (laptop or desktop version) has several operating systems, then select the appropriate one from the list and then hold down F8 again to switch to Windows Safe Boot Mode.
Problems with the monitor or accessories
The reason for the black screen may lie on the surface: the monitor does not work. This may be due to the fact that the contact between the monitor and the video card has disappeared, or the power cable has been damaged / not plugged into the outlet. So be sure to check the connection.
As for the laptop, it is unlikely that the matrix "fell off" from the motherboard. To disable it, you need good reasons: for example, a mechanical effect on the display. In this case, you will see that there are obvious damages on the screen: scratches, broken pixels, etc.
In addition to the monitor, we advise you to examine the system unit. Check if the video card is fixed in the appropriate slot on the motherboard, if there is voltage supply to all PC components. This should be done only if you have the skills to assemble / disassemble a computer / laptop.
Solving conflicts with the video driver, if the computer does not start, a black screen is displayed
An example of a similar problem:
Installed Windows 7, 10, restored to factory settings (native Windows image). But nothing helps. Simply put, when you turn on Windows 10 for the first time, everything is buzzing and everything is fine, but as soon as the drivers are installed on the video card (intel hd3000 and radeon 7600), flickering and a black screen occur, after which recovery and safe mode do not work. That is, Windows 10 dies, after installing the drivers, a black screen.
If you think that the black screen problem may be due to a conflict in the video card drivers on your computer or laptop, then:
- In the Secure Boot menu, select "Enable Low-Resolution Video Mode".
- After successfully logging into the operating system account through Device Manager or Control Panel, uninstall the conflicting ATI/NVIDIA video driver.
- Restart your computer
- There may be a conflict between the motherboard and video card drivers. You need to try different combinations of drivers. In order not to reinstall Windows every time during experiments, create a restore point and roll back to the previous restore point when a black screen appears.
- If the OS loads correctly in the normal mode (the Desktop and the Windows cursor appear), then the black screen problem is really related to incorrect behavior after installing the drivers. Go to the graphics card manufacturer's website and download the latest version to your hard drive, try updating the drivers again.
- If the black screen continues to appear, try other solutions outlined in this guide - for example, remove "harmful" programs.
We remove programs that conflict and block OS loading when turned on
Windows 7 does not start for me. When I turn on the computer, after the words "windows start" a black screen appears and the computer does not boot further. There is no cursor. I restart the computer, I am given a choice of how to boot Windows, I choose normal mode - and everything turns on, sometimes you need to restart several times. Normally, it does not turn on at all, I have Ccleaner, I use it, the antivirus is Avast, I do not update any drivers. What could be the problem?
In this case, the sequence of actions for troubleshooting the problem will be approximately the same as in the above case. The only thing that in Windows safe boot mode is to select the "Enable safe mode" item. Next, in this boot mode, you need to go to the control panel and in the "Programs and Features" window, sort by the date the applications were installed. Analyze what you have installed recently: it is possible that conflicting applications are the cause of the black screen and inadequate loading of Windows from the system disk on your computer. One of the best programs for uninstalling applications is the free utility CCleaner.
Disable unnecessary programs and services from Windows startup
There is a wonderful utility msconfig, with its help you can speed up the loading of Windows. Although modern computers load the OS quickly, boot optimization can remove the black screen for a few seconds.
- Start - Run. In the window, enter msconfig.
- Services tab - here you can disable unnecessary services.
- Startup tab - to enable/disable programs on startup.
In Windows 10, startup items can be disabled through the Task Manager (Startup tab). The status column displays the status of the application.
We use a restore point to roll back the system on the computer and fix problems on the computer
It happens that it is impossible to identify the cause of the OS failure, removing drivers and programs that cause conflicts does not help: all the same, a black screen appears when the computer boots.
If the computer does not start, use the previous Windows restore point
Using a boot disk (Live CD) to fix errors and diagnose a black screen
When a black screen appears, it is advisable to check the computer, operating system for viruses. This can be done using a "live CD". We advise you to use to enter the system recovery mode. In addition to the actual virus scan, livecd 4MRescueKit includes modules for data recovery, file backup and a disk manager like PartitionMagic. Even if this does not help get rid of the black screen of death, you can at least prepare for reinstalling the operating system or diagnose the health of the hard drive in this mode. Live CD fixes problems regardless of the version: it can be both Windows and Linux.

Black screen during Windows reinstallation
I get a black screen and a cursor, I reinstalled Windu and still I can’t completely reinstall it. After the first reboot, during the installation process, when loading Windows, a black screen and a cursor.
Solution to the problem.
- Try a different installation disc or version of Windows.
- The reason for the black screen and boot interruption can be both software and hardware. For example, the hard disk contains bad sectors or the USB flash drive or the disk from which Windows is being installed is damaged.
- Try installing the operating system on another hard drive partition.
Viruses damaged Windows system files
Many computer viruses are capable of deleting or damaging important system files. As a result, after loading Windows, a black screen appears, although the cursor may be displayed and react to your movements. Not always removing viruses helps to solve the problem, but you can try.
How to check a hard drive for viruses if? You need a working computer to which you can attach a hard drive. After booting under Windows, install the free antivirus Dr Web CureIt. The CureIt utility contains up-to-date virus databases.
Video instruction:
Select a hard drive to scan and launch the scanner.
If, after detecting viruses, a black screen still appears when Windows boots, then you need to look for other reasons.
We burn a USB flash drive for recovery and reinstall Windows
After updating Windows 7 - a black screen in any mode: normal, safe - no difference. I tried to restore Windows through the installation disk - to no avail.
Answer. Install Windows 7 from scratch or immediately install Windows 10, thereby killing two birds with one stone: update and solve the problem with a black screen when loading Windows 7.
One of the best programs to burn Windows to a USB flash drive is Rufus. The utility is available in Russian, it is free and, as a rule, writes reliable usb flash drives for installing Windows.
The worst thing that can happen: the hard drive is out of order
Finally, one of the most pessimistic outcomes. If you see a black screen and the cursor is still visible, then the hard drive is working. If there is nothing but a black screen, the OS does not load, then it is quite possible that the computer does not see the hard drive and, accordingly, Windows does not boot. Following the link, you can read the manuals that will allow you to diagnose a hard drive and find out: is it possible to repair, restore data by loading the operating system, or is it better to immediately go to the store and purchase a new HDD for a computer or laptop.
Summary. In this guide, I tried to remember and collect from the Internet the most complete list of problems that cause a black screen to appear on a PC. The OS version doesn't really matter, Windows 8, Windows 10 or generally outdated XP. If none of the methods helped, something is not clear, or you have your own ways to solve this problem - please ask questions and add your ideas in the comments.
Answers to questions from readers
I have a black screen after loading Windows, I tried everything, but nothing helps: I turn on the computer - a black screen, and nothing can be done about it. The bottom line is that the black screen appears only after I update the drivers for the video card. If you put the standard VGA, then everything starts and works fine.
Before that, I completely reinstalled Windu and everything started somehow unexpectedly with "nothing". How to fix black screen when loading windows?
Answer. One of the surest ways to resolve conflicts between OS and drivers on your computer is to go to the website of the manufacturer of your video card and download the latest or stable drivers, not in beta, to disk. When downloading, make sure that you specify your operating system in the same bitness (32-bit or 64-bit). It is also possible that your video card is outdated and is not supported by modern operating systems, in particular Windows 10.
If your laptop has a black screen, try updating your drivers
I have Windows 10 installed. When trying to restore the OS from a system image, it failed. Now a black screen with a flickering cursor in the upper left corner when turned on. All I can do is turn on the computer and enter Bios.
Answer. If you see only a black screen and a cursor, this is a sure sign that the operating system cannot boot (you already understood this problem).
If the recovery console or Windows 10 installation disc does not help you roll back the OS to its original state or restore point, create or a new disk to restore or install the operating system from scratch.
Not a single folder opened, I decided to run . A black screen with a cursor appeared on the laptop when turning on / starting the Windows OS. I did everything according to your article, but the screen is still black. Help me please.
Answer. If a black screen appears when you start windows even after recovery, it makes sense to reinstall the operating system on your laptop in another way - for example, in the boot mode of a flash drive or disk. Since, according to your description of the problem, the cursor still appears on boot, this is a software error, not a hardware one.
An external box was connected via usb for formatting ext3 with the PartitionMagic program. After formatting, the laptop was restarted and there was no reboot, and a message appeared on the black screen: error loading operating system ... The laptop no longer boots, it does not respond to any keys ... OS XP ... how to be, it practically everything, there is a 2nd PC with Windows 10. In other words, the laptop works - but the screen is black.
Answer. Luckily, your laptop is dealing with a software glitch, not a hardware failure. All you need is to reinstall the Windows operating system. After that, the black screen of death will no longer make itself felt. If your laptop has a disk drive, use the boot disk to restore the OS. Otherwise, it will help you, it is not difficult to write it down, read the instructions at the link.
I have a black screen when I turn on my computer. Nothing appears on the monitor when I turn on the computer, and the system unit is working. I did one trick: I pulled out the power, held down the button to turn it on for 5 seconds, let it go, inserted the power cable, turned on the PC - everything worked fine. 3 days later, same thing, but this trick doesn't work. I think this is the wrong shutdown. I turned it off the last time when I had some programs still running (I have Windows 7) and after loading the Desktop does not appear. What should I do if my computer has a black screen?
Answer. You need to approach the problem in a complex way: find out if the motherboard and the power supply are working properly in general, whether all the wires are connected exactly to those power connectors, whether the PC components are tightly connected to the sockets (for example, very often the “black screen of death” is associated with incorrect connection video cards). Perhaps the problem is still not hardware, but software (it's just not clear from your question whether Windows boots). In this case, reinstalling from a boot disk or restoring in LiveCD mode will help.
Help me understand what's wrong with the PC. I have Windows 7. After the startup starts, a black screen and a cursor appear, after which it is suggested to select the Windows 7 OS and the recommended boot or the usual one. After pressing them, the download starts and throws it back into the same settings. The same problem with loading in safe mode. Doesn't offer anything further, there is no window to enter explorer.exe.
Answer. If, when trying to boot Windows 7, a black screen and the cursor continues to appear, which mode you have not selected, most likely, Windows system files have been deleted or changed. A clean reinstall of the OS or recovery from a Windows 7 boot disk will help. In the boot menu, select “System Restore” and then use the Bootrec.exe utility. Further actions are described.
I have an AMD Radeon video card with 512 mb of memory, it did not pull new toys, and I found on the Internet how to increase the memory of an integrated video card through bios. I changed some settings in the bios and set 1 GB of memory, my PC rebooted and I looked at the characteristics of the video card and yes, in fact, the memory has increased. Then I started playing games, about an hour passed and my mouse began to freeze, turn on and off by itself, and then it stopped working altogether, I decided to restart the PC and after that on my monitor I saw just a black picture with some number in the corner. The computer refused to turn on, after probably half an hour of clicking on the mouse and keyboard, "welcome" appeared on the screen. The PC turned on, but the mouse did not work, I rebooted again - and again a black screen for a very long time when the computer was booted up. What could it be and how can I get rid of it?
Answer. This is what overclocking the video card leads to. You need to go into the BIOS and reset to factory settings (set by default). Perhaps it is precisely because of the BIOS settings that Windows does not start.
You are still lucky: during such overclocking of the video card, problems with the temperature of the video card may occur, up to the failure of one of the components (for example, the processor) out of order.
In general, it is not always possible to trust such overclocking instructions. Even if it contains correct information, in the absence of proper skills, you can get not only a black screen, but also black smoke from the system unit :).
I don’t know after what it started, maybe after defragmenting the hard drive, after updating drivers, etc. Every time before Windows boots up, a black screen is displayed for 10 minutes and only after that the welcome window appears. The BIOS definitely boots first, pressed F2 to check the boot device priority in the BIOS. Also, during a black screen, the console caret (bottom slash) sometimes appears. What causes a black screen when loading Windows?
Answer. In the BIOS, you can not only set the boot priority, but also disable unnecessary devices (for example, a drive). However, this will not save the situation.
Perhaps the reason lies in the fact that when Windows boots up, it tries to find the right library or load a non-existent component. Go to the startup menu and disable all unnecessary items. You can also disable unused Windows services through msconfig and remove unnecessary applications on the computer. In general, it is desirable to optimize the operation of the operating system and eliminate conflicts.
You can also analyze the stages of loading Windows through the built-in tool "View Event Logs". This utility will show how long it takes to load each process at OS startup.
If time permits, reinstall the OS. On modern computers, reinstallation takes no more than half an hour, and this is a more rational way to solve the problem of a black screen than many hours of troubleshooting. Sooner or later, any Windows operating system is overgrown with problems.
Black screen when loading Windows 10. This happened after installing drivers from driverpack. After the system starts, a black screen is displayed, while the cursor is visible, there are sounds from programs that were open in the browser (VK). It does not react to anything, the reboot did not help, it also does not enter safe mode.
Answer. You can use a Windows 10 boot disk or flash drive, select recovery mode, and select a rollback point before installing drivers. The black screen after loading Windows 10 will disappear. You can enter Windows Safe Mode through the Windows installation disk, other OS boot modes are also available there.
If you can insert another video card into the system board, you can try the system and remove the drivers manually. Then change the video card to the old one - it should work.
I have Windows 7 on my computer. Everything was fine, but once after entering the bios password there was no Windows boot icon, and the monitor turned off (went into power saving mode), the f8 key did not work. I can't get into bios because the monitor is not working.
Answer. Try resetting the BIOS by removing the battery from the motherboard.
We go further. The power-saving mode will not work immediately after starting the computer; rather, the problem is related to one of the components. Check the connection of the video card to the motherboard, the video card to the monitor, etc.
If everything is in order with the BIOS, and Windows 7 does not boot, reinstall the OS. Apparently, this is the easiest method to get rid of the black screen.
Windows 7 32bit was installed. After changing to Windows 7 64bit, a black screen began to appear. When connected to the TV, everything works, everything shows, everything is fine. But through the vga-monitor does not see and the screen is still black.
Answer. It is possible that the drivers for the monitor or video card were not installed in the 64-bit version. Check the manufacturer's website to see if the monitor supports this OS. There is a suspicion that your particular vga monitor is not supported by this edition of Windows. Try booting Windows in safe mode or with the "Enable low resolution video mode (640×480)" option.
I am using Virtual Box. I installed Linux, worked on it, then turned off the virtual machine. When I tried to run, a black screen occurs after loading with an underscore at the top left. The laptop itself works, the virtual machine does not.
Answer. If you save the state (Suspend) on the virtual machine, in principle, no problems should arise. If you turn off the virtual machine, then Linux tries to boot when you turn it on. Why a black screen with an underline occurs after rebooting Linux is a separate question. Check the key settings of the virtual machine. If the error persists, try installing Linux on Vmware Player.
I have such a problem. It costs Windows 8.1, installed a third-party theme, decided to delete it, deleted the entire themes folder from windows, although not all files could be deleted, well, that's okay, I restarted the computer and after choosing the OS I have a black screen and, no, no, the cursor appears and disappears and bottom toolbar, tell me how to get rid of the black screen? There is no restore point, no image, and no OS disk either.
Answer. If possible, find a USB Boot image or the like on the Internet, write it to a USB flash drive. Find the Themes folder on the Internet or on a disk and, with administrator rights, copy it to the same place where you deleted the files.
Without the installation disk, it is unlikely that you can get rid of the black screen in any other way.
Nothing appeared when I turned on the computer. the light indicates that the camera is working and the computer is on, but the screen is zero. What is the problem - RAM or hard drive? How to check?
Answer. To diagnose the problem, it is desirable to recall previous events. Did the computer show any symptoms of failure (hard drive noise), did you delete system files on the drive, etc. This will help narrow down the list of possible causes. Next - track at what stage the black screen appears. If the hardware initialization is successful, then the problem is in the operating system - that is, Windows does not start. In this case, we advise you to reinstall the OS from a bootable USB flash drive or disk.
You turn on the computer, watch how windows 7 starts loading slowly, the desktop should appear just about now, but instead of it, your eyes have opened ... "Malevich's black square". No wallpaper, no icons on the desktop - just a cursor in the form of a white arrow, and even then not always. What is the reason for the black screen on boot in windows 7? How to solve a problem?
Causes of black screens of death when loading windows 7
- Failure to install system updates, drivers and programs - because of this, pirated copies of windows often suffer.
- Virus infection - most likely the malware tried to replace the system files, but for some reason could not and instead broke the download.
- Corruption of critical startup files or registry keys responsible for this.
- Video subsystem problems, including video driver failure.
- Other hardware malfunctions (rare).
Damage or deletion of windows files can occur due to failures in the computer's power supply system (the lights were turned off at the wrong time), user actions (deleted by hand), defects in the hard disk surface, and even such exotic reasons as treating the system with one well-known antivirus.
Ways to solve the problem
Last Known Good Configuration
In the simplest cases, if the cause was a minor failure, rolling back the system to the Last Known Good Configuration will help. Last Known Good Configuration is the state of windows at the time of the previous successful run. To return to this state, launch the Advanced Boot Options menu. To do this, quickly press the F8 key several times before starting the system.
You will see a list like this:
Select the indicated item from it and press Enter (enter). If the computer starts normally, the problem is solved.
Launching File Explorer Manually
It happens that a failure of the graphical shell leads to a problem, when the file itself responsible for this is not damaged, but only its launch is broken. This is where Task Manager can help you resolve the issue. Press Ctrl+Alt+Delete or Alt+Ctrl+Shift to call it. In the Manager window, go to the Applications tab and click the New Task button.
In the "Create a new task" box, type "explorer" and click OK. If you see the desktop, the problem was exactly what we thought it was.
Now you need to fix the Explorer.exe launch key in the registry - the windows shell, which creates the user environment familiar to us - the desktop, folders, and so on.
Run the registry editor - Regedit.exe. (it is located in the C:\windows folder). Open section. In the right half of the window, find the "Shell" parameter and see what value it has. Normally it should be "Explorer.exe", but you probably have something extraneous there.
Right-click "Shell" and select "Edit".
In the "Change string parameter" box, enter the new value. What - you already know.
Next, open exactly the same section (Winlogon) in the HKEY_CURRENT_USER branch - settings for the current user are stored here. If there is a "Shell" parameter among them and you didn't create it, delete it.
Now it remains to find and delete the file that was registered instead of Explorer, since this is an obvious malware. You can do it manually or with the help of antivirus programs. The second option is preferable as it may not be the only malicious file on your machine.
Restoring the system from safe mode
If neither one nor the second method helped, most likely a more serious failure occurred. You can try to deal with it from safe mode. To load it, also press F8 several times before starting windows, but now select "Safe Mode" from the menu.
Here we have the opportunity to return the state of windows to the date preceding the problem. And the application "System Restore" will help in this. Expand "Start" - "Programs" - "Accessories" - "Utilities". Select System Restore.
To confirm your selection, click "Finish" and wait for the restore process to complete.
It will not be superfluous to additionally check the system files for integrity using the windows console utility - sfc.exe. To do this, open "Start", enter "cmd" in the search box and run the command prompt as administrator.
Type "sfc /scannow" into the console window, press Enter and wait for the scan to complete. Sometimes the system asks for a disk with a distribution kit to restore files, but more often everything you need is restored from storage on your hard drive.
To find out if the video card or video driver is the cause of the failure, run the msconfig system configuration utility (just like you launched cmd through the search box in Start).
Reboot to normal mode. If windows can start, the problem is in the video subsystem. First, update your video card driver, check for overheating of the GPU, and if possible, test the computer with another, known to work video card.
Using the recovery environment
If the previous option did not help, or you also see a black screen in safe mode, there is still a chance to fix the failure through the recovery environment. It also has the ability to run a system rollback and check files for integrity, but there are also special options: restore boot and restore windows from a saved image.
To get into the recovery environment, select from the F8 menu (the key you pressed before starting the boot) "Troubleshoot your computer."
Following the instructions, go to the recovery options window. Select the top item - "Startup Repair". The program will automatically check the data responsible for this - boot files and registry keys, and restore it in case of violation.
The second item from the top is the launch of the System Restore application, which we met at the stage of solving the problem from safe mode. It is useful in cases where safe mode fails to find any checkpoint. It happens that points exist and are created, but the system does not notice them. And here, in the recovery environment, there are no obstacles for this.
The function works exactly the same as in safe or normal modes, so we will not consider it.
The next item is restoring windows to a working state from a backup copy. If you saved such copies to external media (disks), insert the disk into the drive and specify the path to it.
Most users find it unnecessary to spend time creating backup images, so if you do not have such a disk, move on. We have one more tool - the command line. With its help, we can open the explorer and manually restore the system registry.
Once every 10 days, windows 7 saves copies of the registry files in a separate folder. We can take them and move them to where the current, used registry lies. If the failure is related to its damage, the problem will be solved.
Open a command prompt and launch notepad (for those who don't know, this is done with the "notepad" command). Click "File" and then "Open". Navigate through Explorer to the "Computer" folder. Please note that here, in the recovery environment, the drive letters may be different.
Open the \\windows\System32\config\regback directory. To see the contents of the folders, in the "Type of files" field, select "All files". Copy all 5 files one by one and put them in \\windows\System32\configfig folder. This is the register.
Files of the same name in \\windows\System32\configfig must be renamed beforehand. For example, add the .OLD extension to them.
Close File Explorer. That's all. Restart your computer and try to boot windows 7 in normal mode. Let's hope you can do it.

How to fix black screen when loading windows 7
Least of all, when you turn on the computer, the user wants to see how it appears before his eyes not the desktop of the system, but a black screen when windows 7 is loaded. "Black Screen of Death" (BSES).
However, if before the eyes of the owner of the computer the BSEC was displayed only with a white cursor on the computer display, then before proceeding with a drastic measure, like reinstalling Windows, it is recommended to use the instructions below. The detailed guide describes the situation when windows 7 does not boot normally on a computer or laptop and what to do when a BSEC appears.
Why the BSEC appears
If you want to effectively remove the problem, firstly, you need to analyze the possible causes of its occurrence.
The main reasons for the display of the BSEC when starting Windows 7 are the following:
- If nothing appears on the black screen at all, there is no mouse cursor and no inscriptions in white letters, then the reason is probably in the video system, for example, a video card driver failure;
- Problems updating OS and software;
- The presence of "broken" system files required when starting the system;
- The action of malicious applications (viruses);
- Computer hardware defects.
The easiest way to troubleshoot
In simple situations with small failures, you can effectively and quickly solve the problem using windows 7 restore points, i.e. roll back the OS.
Using Registry Editor
What to do when the file responsible for the graphical shell is not loaded correctly.
To remove this defect, do the following:
Solving the problem through safe mode
If none of the above solved the problem and the OS does not boot normally, then there is nothing left to do but start the PC in safe mode and do subsequent debugging of the system in it.
This mode is loaded as follows:
- Before starting the OS, quickly press the "F8" button, after which a screen with white letters appears, where you are prompted to select a method for booting the OS;
- Place the cursor on the line "Safe Mode" with the arrows and click on "enter";
- Wait until the end of the PC boot process in Safe Mode.
Now you can try to return Windows to the state before the problem occurred. To do this, you need to do the following:
Through the recovery environment
In the case when the above methods did not lead to success, and the normal windows desktop did not appear, it is recommended to continue working further using the recovery environment, where there are much more options.
To this end, you must perform the following sequential steps:

Black screen and cursor when loading windows: what to do?
Despite the attractiveness of the tenth version of the windows operating system, after installing it or installing updates, you can often find moments when, instead of the expected system boot, a black screen and a cursor appear, which sometimes may be absent. What is the reason for this phenomenon and how to deal with it, read on.
Black screen and cursor when starting windows 10: what is the reason?
In general, for all operating systems of the windows family, such a problem, as a rule, is the result of incorrect operation of the video adapter, despite the fact that when you turn on the computer, the BIOS signals that everything is in order with the system and all devices are working normally (this is determined by the long signal of the system speaker ).
But not everything is so simple. The operating system itself is such that the graphics accelerator is not always directly related to the problem that a black screen appears at startup. What to do, not everyone knows. Meanwhile, it is worth paying attention to some components of the OS itself. First of all, these are incorrect work or malfunctions of the explorer.exe service, disabled fast startup, activated relicensing, outdated, incorrectly installed or missing video card drivers.
System Restore
The black screen and cursor when starting windows 10 can be removed in several ways. However, the simplest solution may be to force a computer or laptop to shut down and then reboot (the method, of course, is quite barbaric). But after that, either the hard drive can be checked for damage to system files and bad sectors, or the system recovery tool will start working.
In the second case, all operations will be performed automatically without user intervention. It is very likely that after half an hour of waiting, depending on the hardware configuration, everything will return to normal. If this solution does not work, you can use either an installation disk or a recovery disk (or USB flash drive), but you need to take care of creating such media in advance.
Return to the old system
If the tenth version was installed over an existing one as an update (for example, windows 7), you can use the rollback tool (only if the 30-day period has not expired since installation).
To do this, enter the settings section and select the update and security section there, and then use the appropriate line.
By the way, after that, a black screen and a cursor may appear when starting windows 7 (meaning the situation after returning to the old OS). And here the reason must be looked for already in the drivers of the graphics accelerator.
Problem: Black screen on system startup. Update video card drivers
Updating video card drivers is a fairly effective method. It often helps in situations where two cards are installed in the system - discrete and integrated. Basically, failures concern discrete cards.
In this case, you can switch to the integrated accelerator. In parallel, you will have to reinstall or update the drivers of the main adapter (it is advisable to completely remove them first). This is done in the "Task Manager" by calling the appropriate commands in the RMB menu.
Safe Mode and Command Prompt
The black screen and cursor when starting windows 7 or 10 can be removed by another universal method that many computer users do not know about. You need to use the command console (no difference, in a booted system or when starting from removable media).
In the installed system, loaded in Safe Mode, the command line must be launched as an administrator; when booting from a disk or flash drive, no selection is required. The line bcdedit / set (globalsettings) advancedoptions true is written in the console, after which, when restarting, it will be possible to select tools for working with the system.
The command line in the current system is called up through the Run menu with the cmd combination, in the recovery console on removable media, use Shift + F10.
In the console itself, you need to register sfc / scannow and wait for the integrity check of system files to complete. Perhaps this procedure will help. Indeed, well, do not overwrite the entire bootloader and boot area (although this is quite simple to do).
Restarting the explorer.exe service
Another option that users encounter when trying to figure out why the black screen and cursor hangs all the time is related to the Explorer service (not to be confused with "Explorer").
Alternatively, if the system still comes to life, you can use the process restart (if the screen hangs, you will have to act blindly). Here you need to call the "Task Manager", end the explorer.exe process through the RMB menu, and then start it again. There is also a quick restart command in the menu, but I think it is not effective enough, so it’s better to complete the process first, and only then restart it.
You can also use another method. For normal loading at startup, the spacebar is pressed several times, and then the Tab key five times.
Enabling Fast Startup
All actions to configure the system, of course, it is desirable to perform in safe mode (this is not mandatory, but recommended).
But the black screen and the windows 10 cursor may also appear when installing a power scheme, which for some reason failed. In this case, you need to go to the appropriate section from the "Control Panel" or call it from the RMB menu on the battery icon on the laptop. On the main page, you just need to check the quick launch line when you exit sleep mode or hibernation state (if they are enabled).
Disabling reactivation
The black screen and cursor may also be the result of the reactivation service being enabled. Accordingly, the solution is to disable it.
Using the "Explorer" or any other file manager, you need to enable the display of hidden objects and find the windows Activation Technologies directory. On 64-bit systems, it is located directly in the windows directory; on systems with 32-bit architecture, it should be looked for in the System32 folder. Next, you need to delete both the folder and all its contents (if deleting the entire directory at once is impossible, the elements inside it will have to be manually deleted one by one). After that, you need to perform a complete reboot of the system. Perhaps, after that, the black screen and the user's cursor will no longer bother.
Similar actions can be performed in the services section (stop and disable the process), but it will take more time.
Brief summary
Here, in fact, are all the methods that allow finding a solution in such an unpleasant situation. Of course, not all aspects related to the fact that instead of loading the system a black screen and a cursor appear, however, these situations are the most common. And the fact that the video accelerator drivers are to blame for everything is not always the main reason (unless there are conflicts between the system and previously installed drivers, if windows 10 left them unchanged during installation). Here, as we see, the question is also in the system itself. No matter how good it may be, there are enough shortcomings in it. By the way, at worst, you can just try to change the resolution of a stationary monitor from its own menu. Of course, there is little hope for the elimination of the problem, but, as they say, what the hell is not joking ...
But seriously, when nothing helps at all, try overwriting the boot sector using the following combinations:
- first bootrec.exe /fixmbr;
- then - bootrec.exe / fixboot;
- and finally - bootrec.exe /rebuildbcd.
This operation helps in 99% of cases out of 100. When booting from removable media, you may receive a notification that these commands are not supported. It's okay, you can ignore them or use the sfc / scannow system file check command before executing them, along the way - chkdsk / x / f / r and the shutdown -t 0 -r -f command to reboot and check the system's health.
If none of the options fit, you will have to check the system for viruses by booting from a medium like Kaspersky Rescue Disk, and if the system comes to its senses, use the Microsoft Fix It utility, as well as an additional tool - DLL Suite to restore, download and integrate into Windows 10 OS environment missing or incorrectly installed dynamic libraries.

A black screen with a cursor appears instead of the desktop. What to do?
Sometimes windows users are faced with a situation where, after the welcome window of the operating system, instead of the desktop, a black screen appears with a working mouse cursor. Any specialist will immediately answer you that the system was unable to start the explorer.exe process. Therefore, knowing what caused the problem, you can very quickly return the computer to its original state.
Basically, the problem with the absence of the desktop can occur for two reasons:
1) First of all, these are, of course, viruses. Some virus programs make changes to exactly the registry section that is responsible for starting the usual type of operating system.
2) Oddly enough, the appearance of a problem can also be affected by an antivirus, which can remove a malicious file, but not correct the changes it has made.
Black Screen Troubleshooting
1. Open Task Manager. To do this, press the familiar keyboard shortcut Ctrl+Alt+Delete and select the appropriate menu item.
2. In the window that opens, select the "File" tab, then click on the item "New task (Run ...)".
3. A miniature window will open, in which you need to enter the command without quotes "regedit" and click OK.
4. Next, the registry window will appear. Using the left side of the window, navigate to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\windows NT\CurrentVersion\Winlogon branch.
5. In the "Winlogon" folder, find the "Shell" parameter and note its value. If there is a different name from "explorer.exe", then you need to make these changes manually.
To do this, double-click on the parameter with the mouse and in the "Value" column, write "explorer.exe" without quotes.
If this parameter does not exist at all, it must be created. To do this, right-click in an empty area of an open branch and select "Create Stock Parameter". Name the parameter "Shell", and also set the desired value.
6. In the same branch, pay attention to the "Userinit" parameter, which should have the value "C:\windows\System32\Userinit.exe". If the value of the parameter is different or completely absent, follow the steps described in the fifth paragraph.
7. Now go to another branch HKEY_CURRENT_USER\SOFTWARE\Microsoft\windows NT\CurrentVersion\Winlogon and make sure that it does not contain any parameters. If parameters are observed in this branch, they must be removed. Close the registry window.
8. Press Ctrl+Alt+Delete again and restart your computer.
After completing the described steps, the desktop should boot successfully. Just in case, run your antivirus and scan your system. In addition, you can use the free Dr.Web CureIT utility, which will find and fix all problems.

Why does a black screen and mouse cursor appear? Reasons and their solution
Greetings, dear readers.
Some time ago I talked about the blue screen of death in windows. The same article also mentioned options for solving problems. Today I will share useful information regarding another similar case. So, many users are faced with a situation where a black screen and a mouse cursor appear on their computer. At the same time, the latter moves, but this does not give anything at all, since there is no data on the display.
Reason (to content)
If you are faced with a similar situation, do not panic. The first thing to say is that everything is in order with the components.
The problem is that the “Explorer.exe” file does not work, which is precisely responsible for displaying the contents of the “Desktop”. In most cases, the malfunction of this element is associated with the activity of a particular virus. Therefore, if you have the symptoms described above, remember what programs or add-ons you might have installed recently. It could even be a browser extension.
Sometimes there is also the work of modified software, as a result of which when you press “Ctrl + Alt + Del”, the task manager does not even start. But it is not so important which version of the virus got on your computer - the algorithm of actions will be the same.
Solution(back to content)
One of the surest ways is to completely reinstall the operating system, whether it's windows XP, Vista or any other. After all, malware is usually first located on the system drive. If you format it, the virus will also disappear. But not everyone is ready to do this, because often by this time some important files are already on the system partition, which cannot be deleted.
The main solution can be called a rollback of the configuration. But for this you need to return the visualization. What to do in this case? We get to the command line.
So, in Win 7 and other latest OS versions from Microsoft, the complete solution looks like this:
It is worth noting that this method is also suitable for windows 10.
As a result, users get a fully working OS, without reinstalling it and with saving all files.
Sometimes after the completion of all actions, you can observe a black square instead of a cursor. This occurs when some additional files are damaged as a result of the virus, or they simply do not start. To return the situation, we reboot. If it doesn't help, try running an earlier version of the operating system.
Well, I told you how to fix the situation when your desktop suddenly does not load. This method is simple - the main thing is not to press anything extra.
The current situation allowed us to draw several important conclusions at once. Some I have already voiced in articles earlier, others will sound for the first time:
You can download a virus to your computer and activate it even without a file with the *.exe extension. Simply install a seemingly harmless browser plugin. Therefore, before such actions, it is advisable to check the supplier. Or at least look at the reviews.
If you look at the situation as a whole, it is solved with the help of two teams. There is no need to even watch videos or study many pages of instructions. Everything is simple.
Do not disable a tool such as System Restore. You can't know exactly when it will come in handy. This trend has gone since the use of XP OS, because at boot a hidden directory was automatically created, taking up extra space. In addition, it is here that you can find a lot of viruses (according to the messages of the corresponding programs).
Problems need to be fixed as they come up. Otherwise, you can not restore the system, but on the contrary - spoil it as much as possible. The only solution is to reinstall the operating system. So, first run "Explorer.exe" and then restore the system.
I hope you have found something new for yourself. Subscribe and tell others.
