Updating is a potentially dangerous procedure, as it involves changing a critical important files systems. When unsuccessful update all sorts of problems can occur, including a black screen. The reasons may lie in different places, in order to indirectly determine the root of the problem, it is important to focus on the moment when the display disappears from the monitor. Depending on this, you should perform system diagnostics and recovery.
The monitor itself rarely causes inconvenience, mostly the problem lies deeper. The root of the problem is the absence of a signal from the video adapter or system failure... To determine what exactly caused the failure, you will need to do step by step actions presented in further instructions.
Experience has shown that the problem is primarily due to driver failures. There are several options here, the environment has changed, and the driver is the same or is not installed correctly. The main difficulty in the situation is that there is no way to see the desktop for reinstalling the video driver from the desktop.
To fix the problem, you will have to perform several manipulations to return the screen display. All methods are divided depending on when the problem occurs.
Display disappears before login
Several options have been identified that can help you get the image back at this stage. Windows boot.
Entering recovery mode
This option is relevant for display problems arising on different stages launch.
Changing the video port configuration
It happens that together with Windows update, some kind of failure occurs, in which the flow of information to the monitor is made, but to a different port. You should check if the display works by switching it to a different port, this may require an adapter (usually included).
In desktop personal computers, often, it is possible to connect to the integrated video card located on motherboard.
The display from the monitor may disappear if another screen is selected, which may simply not exist. To switch between modes, hold Win and press the English P button. You can do this 4 times to iterate over all the display options.
No display after launch Windows 10
Here the mouse cursor is displayed, but there are no desktop elements. It is in the explorer.exe process that the problem lies, it is responsible for the entire desktop. To run it you need:
- Press Ctrl + Alt + Del;
- V top menu click on the first item "File";
- Then "New task";
- In the line that opens, enter explorer.exe and press Enter.
After this action, the desktop should appear, but the problem is not resolved, when you restart it will return again. Detailed analysis methods for solving the error are presented in the article.
Hardware driver failure
Apart from the problem with the process, the root may be in additional equipment installed on your computer, try temporarily disabling everything unnecessary.
If the problem is solved in this way, you should connect the devices one by one until you determine the right one. Then uninstall the hardware driver from Device Manager and install it again.
High Contrast Mode
The problem can also be caused by this mode. You can check whether you have it installed or not from the "Safe Mode", as described earlier, and then press Win + I. Then you will see the item " Special abilities", And in it the function we are interested in, make sure that this mode not involved.
Processes
Due to certain failures in the system, wrong job service or process RunOnce. Disable them and check the result. This is done from the "Task Manager", in the "Processes" and "Services" tab, search for necessary items named RunOnce and stop them.
Hard drive problem
Occurs when there is broken sectors, changes in the structure of the HDD or problems with its launch. Quite often helps simple reboot computer, you may need to perform this action several times. May I help Victoria program by running it in safe mode and scanning the system.
If you still have questions on the topic "Black screen in Windows 10 after the update, what to do?", You can ask them in the comments
if (function_exists ("the_ratings")) (the_ratings ();)?>
After updating or Windows installations 10, and also after a normal reboot already successfully installed system you have a black screen with a mouse pointer, and you do not know what to do, do not rush to get upset and delete the system, there is a way out. In general, this glitch has been going on since Windows 8.1, earlier I told you how the black screen is eliminated in windows 8.1, I advise you to read it too if the methods presented below do not help you.
The problem is very often related to glitches NVidia video cards or AMD Radeon however, this is not the only reason. In this manual, we will consider a situation when Windows 10 boots, sounds are heard, but nothing is displayed on the screen except for an annoying mouse, or you may face another possible situation when a black screen appears after sleep or hibernation (or after turning off and then turning on the computer) ...
Note: In some cases, in windows 10, a black screen may be caused by a connected second monitor. In this case, try disabling it, and if that did not work, then go into the system blindly (described below, in the section on rebooting), then press Windows + P, once the down key and Enter.
Note 2: If you see the login screen, and after login, a black screen appears, then try the next option. On the login screen, click on the on-off button at the bottom right, and then, while holding Shift, click "Restart". In the menu that opens, select Diagnostics - Extra options- System Restore .
Restart Windows 10
One working way to fix black screen issue after re-running turning on windows 10 appears to be quite workable for owners AMD graphics cards(ATI) Radeon - Completely restart computer and then disable quick start Windows 10.
In order to do this blindly, after booting the computer with a black screen, press the Backspace key several times (left arrow to delete a character) - this will remove the lock screen saver and remove any characters from the password input field if you accidentally entered them there.
After that, switch the keyboard layout (if required, by default in Windows 10 it is usually Russian, you can switch almost guaranteed Windows keys+ Space) and enter your password account... Press Enter and wait for the system to boot.
The next step is to restart your computer. To do this, press the Windows + R keys on the keyboard, wait 5-10 seconds, enter (again, you may need to switch the keyboard layout if you have Russian by default):
and press Enter. After a few seconds, press Enter again and wait about a minute, the computer will have to reboot - it is quite possible that this time you will see an image on the screen.
Second way restart windows 10 with a black screen - after turning on the computer, press the Backspace key several times (or you can use a space or any symbol), then press the Tab key five times (this will take us to the on / off icon on the lock screen), press Enter, then the " Up ”and Enter again. The computer will then restart.
If none of these options allow you to restart your computer, you can try (potentially dangerous) forced shutdown computer by holding down the power button for a long time. And then turn it back on.
If as a result of all the proposed image appeared on the screen, then it is precisely in the operation of the video card drivers after a quick start (which is used by default in Windows 10) and to prevent the error from repeating.
Disable Windows 10 Fast Startup:
Click right click mouse on the Start button, select Control Panel
On the left, select what the power buttons do.
At the top, click "Change settings that are currently unavailable."
Scroll down the window and uncheck the "Enable Fast Startup" checkbox.
Save your changes. The problem should not be repeated in the future.
Using integrated video
If you have an output for connecting a monitor not from discrete graphics card, and on the motherboard, try turning off the computer, connect the monitor to this exit and turn on the computer again.
There is Great chance(if the integrated adapter is not disabled in UEFI) that after enabling, you will see an image on the screen and you can roll back the discrete video card drivers (through the device manager), install new ones, or use system restore.
Removing and reinstalling graphics card drivers
If previous way did not work, you should try to remove the video card drivers from Windows 10. You can do this in safe mode or in mode with low resolution screen, and how to get into it, seeing only a black screen, I will now tell you (two ways for different situations).
First option. On the login screen (black), press Backspace several times, then Tab 5 times, press Enter, then up once and holding Shift, Enter again. Wait about a minute (the diagnostics, recovery, system rollback menu will load, which you probably won't see either).
Next steps:
- Down three times - Enter - down two times - Enter - left two times.
- For computers with BIOS and MBR - down once, Enter. For computers with UEFI - two times down - Enter. If you do not know which option you have - press "down" once, and if you get into the UEFI settings (BIOS), then use the option with two clicks.
- Press Enter again.
The computer will restart and show you special options downloads. Using the number keys 3 (F3) or 5 (F5) to start Low Resolution Mode or Safe Mode with Networking. Once booted, you can either try to run System Restore in the Control Panel, or delete the existing video card drivers, after which, restarting Windows 10 in normal mode(the image should appear), reinstall them.
If this method of booting the computer for some reason does not work, you can try the following option:
- Log in to Windows 10 with a password (as described at the beginning of the instructions).
- Press the Win + X keys.
- Press up 8 times, and then - Enter, the command line will open.
V command line enter (should be English layout):
bcdedit / set (default) safeboot network
and press Enter. After that enter shutdown /r press Enter, after 10-20 seconds (or after a sound notification) - Enter again and wait until the computer restarts: it should boot into safe mode, where you can remove the current video card drivers or start a system restore. (In order to later return to normal boot, in the command line as administrator, use the command
bcdedit (default) / deletevalue safeboot)
Optional: if you have bootable USB drive with Windows 10 or a recovery drive, then you can use them: Windows recovery 10 (you can try using restore points, as a last resort - resetting the system).
Update from 07/06/2017
Update KB4034450 has been released, designed to fix all the problems with dozens of black screens, if possible, install it as soon as possible in safe mode by slipping it through a USB flash drive or disk. I hope this post helped you solve your problem with the new OS from our beloved melkosoft. Site material
- Hello admin! Soon July 29, 2016 - Deadline ends free update to Windows 10 and I decided not to wait for the last day and upgrade, but in renewal process Windows 8.1 to Windows 10 a black screen appeared on the monitor screen, waited half a day, but the screen remained black as it was.On one forum on the Internet, it was suggested to restart the computer and repeat the update process, but unfortunately after the restart I cannot get into Windows 8.1 to start the update process again, the screen is still the same black screen. What to do?
- Hello! I updated my Windows 7 to Windows 10, but the joy was short-lived, after two days the laptop began to turn on with a black screen, then twenty minutes pass (and sometimes an hour), and Win 10 still boots. Is there some way to get rid of this black screen or roll back to Windows 7?
Hello friends! Free upgrade from current Windows 7 and 8.1 to Windows versions 10 will end soon - July 29, 2016. Millions of users around the world have already done this, taking advantage of the upgrade process before installing Windows 10 from scratch. And this is saving data on the C drive, installed programs, transfer activation. However, alas, for almost a year of hype with the upgrade to Windows 10, this process did not always end successfully in computer services began to bring computers and laptops with the so-called " Black screen Windows 10”, Also in various forums on the Internet, requests for help in solving the same problem began to appear.
In my experience black screen Windows 10 can appear in three cases:
- Windows 10 black screen appears at the entrance to the operating system some time after a successful update. One of the scenarios for this error: a black screen with a hovering or moving cursor through long time is still replaced by the launch of the system.
- Another, more hopeless scenario: Windows 10 does not start, the black screen remains the top demonstration of the capabilities of the updated system, no matter how you restart the computer.
- The most hopeless option. Windows 10 black screen occurs in the process of upgrading previous operating systems to Windows 10.
What reasons can lead to such a problem during the update process? current version systems prior to Windows 10? How to fix Windows 10 black screen problem? I offer my solution to the problem of black Windows screen 10 in the above cases.
Friends, if your Windows 10 previously loaded perfectly, and now "pleased you with a black screen", then try keyboard shortcut firstControl-Alt-Delete to run Task Manager,
In the input field enter explorer and click OK.
Your worker is likely to appear Windows table 10.
What's most interesting is that you can then turn off the computer and turn it on, and Windows 10 will start up fine and work without any problems. I came across such a bug many times, but mainly in those cases when computers and laptops with new hardware were updated to Windows 10.
Another easy way to get rid of the black screen. If you have a laptop, just take it out of it battery and install it back, then turn on the laptop, it is quite possible that Windows will boot instead of a black screen.
If two data simple solutions did not help you, then we read the article further.
1. Windows 10 boots: Disable Fast Startup
We all know that Windows 10 uses (and is enabled by default) Fast Startup or Hybrid Boot technology, which allows your PC or laptop to boot into the operating system faster after shutting down, but not after rebooting. Fast Startup technology is based on hibernation. If fast startup is enabled in Windows 10, then the system ends the user session when shutting down, but does not end the system session, that is, it suspends all running system processes and services, writing information about this to the hiberfil.sys hibernation file. When you turn on the computer or laptop, the contents of the hiberfil.sys file are loaded into memory, due to which a quick start occurs, this process very similar to waking up from hibernation.
I want to say that this technology does not always work correctly on all hardware (especially old ones).
If we are dealing with, albeit for a long time, nevertheless a bootable system after updating it to Windows 10, you can try to solve the problem with a black screen by disabling Fast Startup. With the keys Win + Q we call the intrasystem search, enter the query "Power supply".
In the power settings window, click the inscription Power Button Actions.
At the bottom of the window, in the graph Shutdown Options uncheck the "Enable Fast Startup" option. We save the changes.
If this move does not solve the black screen problem and long loading Windows 10, perhaps the reason lies in the video card driver. More on this below, in clause 4 of article.
2. Windows 10 won't boot: how to get into the system?
If all this did not bring successful results, you need to try to get inside Windows 10 using safe mode... But for this, you first need to be in action selection menu Windows 10.
The existing theory that the selection menu Windows actions 8.1 and 10 can be accessed using the Shift + F8 keys while the computer boots, in practice it is difficult to check. The response time to these keys is negligible due to the shortened start-up Windows systems 8.1 and 10. Nevertheless, if someone manages to successfully test the operation of the Shift + F8 keys, once in the action selection menu, then you need to follow this path:
Finally, directly in the safe mode window, press the F4-F6 keys in accordance with the necessary parameters this mode.
More reliable ways start Windows 10 in safe mode - using or. If any of these details are available, go to the article for further instructions.
What to do after booting into Safe Mode?
3. Screen resolution
Windows 10 black screen may be the result of setting a screen resolution that is not supported by the video card. In safe mode, without the video card driver running, the screen resolution will be standard - 1024x768 and the operating system becomes visible. Which will allow you to change the system settings of the screen resolution to lower ones. For example, you can apply the same 1024x768 standard to the system to check if Windows 10 starts. The screen resolution in Safe Mode is set in the same way as in normal Windows 10. On the desktop, we call context menu, choose Screen Options.
Extra options.
Setting permission.
4. Video driver
If the screen resolution is not the reason for the black screen after updating to Windows 10, then you need to check the involvement of the video card driver in the problem. Very often after upgrading from previous operating systems (Windows 7, Windows 8.1) to Windows 10 old driver video card conflicts with the new operating system causing a black screen problem. Removing the video card driver in Device Manager can fix the problem. Expand the item "Video adapters", right-click on the name of the video adapter and select "Delete".
We restart the computer and if it was a video driver conflicting with Windows 10, then the operating system will boot normally by installing the built-in video driver from Microsoft. After that you need or you can manually download latest version video driver from the official website of the video card manufacturer.
5. Viruses
Viruses and other malware - universal reason many problems in the operation of the OS, including the black screen of Windows 10. You can check the system for viruses both in the same safe mode and by booting from antivirus bootable media... Many security software developers have such free emergency Live discs, in particular,.
- Note: Malware infiltrating the system can damage important system files, and the mere fact of neutralizing infected files with antiviruses may not be enough for recovery Windows health... In this case, you need to resort to ... The same process for cases where Windows 10 won't boot is described .
6. System rollback
If before upgrading to Windows 10 for current Windows 7 or 8.1 was created restore point or backup copy(third-party or regular means systems), and all the methods discussed above did not solve the problem with the black screen, it's time to start rolling back the system. Rollback Windows 10, including when it does not boot, is described in detail in the articles on restoring this version of the system and.
7. Canceling the upgrade and reverting to the previous version of Windows
Cancel the update and return to previous version Windows is essentially the only way roll back the system while saving the data on the C drive, installed and configured programs, if there is none backup, nor the restore points made in advance on the eve of the update. Back to previous Windows 7 or 8.1, you can then try to update the system to version 10 in a new way. Naturally, do not forget to make a backup before the second attempt to update in case of failure and the second time. But you can only go back to a previous Windows 7 or 8.1 within a month from the day of the upgrade to Windows 10 and if there is an untouched Windows.old folder on the C drive. How is the upgrade to Windows 10 canceled by regular functionality,.
- Note: It is not recommended to resort to canceling the upgrade to Windows 10 using third-party utilities.
8. Returning the system to its original state
Just as the update process can be accompanied by errors and failures, the reverse cancellation process can fail, even if the monthly deadline for this operation has been met and the Windows.old folder has not been deleted. If the cancellation of the update was unsuccessful, there is neither a backup nor a restore point, while the issue of reverting to a previous version of Windows is essential. In this case, the data stored on the disk (C :), if they are valuable, must be moved to a non-system partition of the disk. In non-bootable Windows 10, this is done, for example, using the one mentioned in. Each of them contains a file manager among the tools.
If we are talking about stationary PCs and laptops without a manufacturer's recovery environment, as well as if there is a desire to continue working with Windows 10, this system can be returned to default settings, as if it were a normal system reinstallation process. This method wins over restoring laptops to factory settings with the ability automatic save files on disk (C :). We read about this in detail.
Sometimes, Microsoft OS users face a problem when after booting Windows only black screen and cursor mice. The symptom is quite famous - it cannot start system process"Explorer.exe" There may be several reasons: a virus or vice versa - antivirus (Avast), problems with hard disk etc. Quite often fix black screen on startup can be done in a minute without any third-party utilities.
As already mentioned in the title - the reason for this behavior is process startup error, which is responsible, among other things, for displaying the desktop, its elements and the panel with the "Start" button. In this recovery guide, we'll look at two popular reasons why when Windows boots up, a black screen and a cursor are visible instead of the desktop. One of the reasons in some cases is the popular Avast antivirus , which, for reasons known only to him, blocks “ explorer.exe". In the second case, you will have to slightly edit the system registry. In both situations Windows work recovers very easy.
Avast is the culprit behind the black screen when loading Windows.
So after Windows booted, but on the screen there is only a black "Malevich square" on which the "abstract cockroach" - the mouse cursor is running, do the following:
- 1. Press the world famous combination of buttons " Ctrl + Alt + Del"And select" Start Task Manager "from the list.
- 2. After the Task Manager window appears, find in the list of processes " avast"(The" Processes "tab) and from the context menu (right-click on the process) select" Open file location ".
- 3. You will see a window with a folder where the Avast antivirus is installed. Find the file "AvastUI" in it and run it (double click or "Enter"). The main antivirus window should open.
- 4. Go to the top tab " Safety", In the list on the left, select" Antivirus", And among the menu items that appear, click on" Behavior screen».
- 5. Open display settings and add to reliable processes « c: \ windows \ explorer.exe"(Use the" Browse "button). We confirm our actions with the "OK" button.
- 6. Restart your computer: again click " Ctrl + Alt + Del»And find the corresponding icon on the screen that appears.
If the Avast antivirus was the culprit, then after performing the steps from the instructions for solving the problem black screen and mouse cursor when Windows startup – next boot operating system should be successful. It is possible that the problem has already been solved by Avast's developers, but the process of adding the program to the "trusted" ones can still come in handy. Moreover, it is not known how the antivirus will react to the upcoming release Windows 10.
If you use another antivirus, then try to find in its settings similar paragraph to create a list of "trusted", "reliable", "ignored", etc. applications that should not be scanned by this antivirus. If the antivirus is to blame, then black screen with cursor at boot Shouldn't bother you anymore. A defender who reacts so inadequately to popular programs, most likely, in the next few days (and maybe hours) will receive the corresponding update. It is quite possible that it will be received automatically if there is an Internet connection and a configured function for updating the antivirus via the Internet. Otherwise, it is recommended to download the updated version from the official website.
Not always mistakes and similar situations on Windows startup caused by antivirus. There may be hardware problems. The review was recently published. But further we will consider the solution when, in the current situation ( only the mouse cursor is on the screen) are to blame wrong parameters system registry Windows.
What if only a black screen and mouse are visible when Windows starts? We correct the system registry.
The first step is exactly the same as in the case of antivirus: you need to open , use it to run registry editor and check / fix a couple of Windows registry values.
- 1. In a state black screen press the world-famous combination of buttons "Ctrl + Alt + Del" and select "Start Task Manager" from the list.
- 2. After the Task Manager window appears in the top menu "File" select "New task (Run) ...". The Create New window appears. new task". In the "Open" field, enter the command "" (without quotes). The Registry Editor window will open.
- 3. In left side windows go to the section (something like "folders" in explorer) with the name " HKEY_LOCAL_MACHINE". Expand it and go to the subsection " SOFTWARE». The same way get to the section " HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon».
- 4. In the right part of the window you will see a list of parameters. Find the parameter named " Shell". Its meaning there should be a line "explorer.exe"... If this is not the case, then after double-clicking on it, set specified value... In the event that the "Shell" parameter is absent at all, then create it by selecting "New" - "String parameter" from the context menu of the "Logon" section. Specify the name of the new parameter ("Shell") and then by double click set the value ("explorer.exe").
- 5. As in point 3, go to the section " HKEY_CURRENT_USER \ Software \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon". Here is the right side should not contain the "Shell" parameter. If there is one, then it follows remove it via the context menu or by pressing the "Delete" button on the keyboard.
The above two methods will help you restore Windows if at startup black screen and mouse cursor... Changing the "Shell" parameter often indicates that a computer has been infected by a virus. It is possible that he has already been neutralized. installed antivirus, but the system may well have left traces of his activities (change "Shell").
It's rare to see a black screen when booting into Windows 10, but it still happens. Various variations are possible: with or without a cursor. It doesn't matter when the problem appeared: after updating, after downloading, by itself, or caused by a virus.
A unified recovery tool is used to fix it. The installed instance allows you to start the mode through shutdown (holding Shift), but in our case you will have to do it differently. Best to get somewhere bootable media although there is another way.
Built-in tool
If the system does not want to boot when you turn on the computer, and the display remains black, try the following procedure:
How to roll back a driver
Usually a dozen does not warn when installing new drivers. Therefore, there is a 99% chance that it is impossible to understand why the system stopped loading. The second problem is that the system does not provide information about the installation date. But if the screen is black, then there is a high probability of graphics failure. From safe mode, enter the Device Manager. We check the installed driver.
If the Rollback ... button is active (as in in this case), press it immediately. There is a chance that after updating the driver, when the computer is turned on, wrong permission screen. Sometimes the problem cannot be fixed after booting in Safe Mode. And instead of the desktop, we see emptiness, although the speakers play a unique greeting melody. In this case, select the option with a low screen resolution.
Installation media
If you see a black screen after installing Windows 10, grab the installation media immediately.
Start recovery
Rollback
Some will want to roll back to a previous version. This is only possible if a dozen have risen recently. In fact, this option is not suitable for most of the citizens after August 2016. Because the rollback is possible within no more than 30 days from the date of the update. Billy Gates has provided the option to update after that date only to “people with disabilities". For them, this item may be relevant.
Recovery point
The dozen is constantly being cleaned, so the restore points disappear. But this is the first system where in 80% of cases there is at least one slice. If the system does not start, use the very first menu item. The OS selection menu immediately appears. Of course, this is a dozen. Then a search will be made, and in the worst case, this is what awaits us.
By this reason The first thing to do when the boot screen doesn't bring up to the desktop is to check the restore points.
Boot fixer
It is not known exactly what this partition does, but after it, the performance is often restored, the system boots and starts working. It is possible that the utility is overwriting the boot loader. We talked about this earlier. Shown several ways to rewrite a section when help diskpart... The text is called that.
Updates
Even powerful computer sometimes hangs for a long time after updating. Give him another chance. As for netbooks, the authors have updated this to ten all night. I did everything myself. After installation, the bit capacity of the operating system increased, and the computer began to play games with 3D graphics.
So, if the shutdown caused a black screen to appear. Before removing this banner, take care to get your bootable media out.
Regular bugs
This is not explicitly stated, but many complain about problems after the update. Perhaps this is a common occurrence, and many are struggling with the same. Look at this topic at least. One and a half thousand people found it useful.
You will see that the problem is not an isolated one, therefore, it cannot be solved in this moment... According to the text, both complaints and angry responses regarding the "raw" product. Just roll back as described above and don't worry about Microsoft issues. It is striking that the list of solutions is extensive, and there are relatively few satisfied people. This system problem solved by rolling back drivers and using restore points.
Create a restore point
A dozen cleans up the custom points little by little. This happens whenever the system creates its own. But just in case, you need to check. Is there at least one point in the system.
Now we are not afraid of any failure, because we can rollback. Always make sure that the system has at least one rollback working slice. This will save you from pointless searches on forums and sites.
