Why is the operating system not working? Changing the amount of virtual memory. The main tasks of PerformanceTest can be called

01.05.2019 Interesting

The main task that the computer diagnostic program performs is to obtain as much as possible more information about the software and hardware of the device.

With its help, determine whether there are enough resources to run specific application, check the characteristics of the system, components and their condition.

Such programs are especially important for a person who, for whatever reason, needs to know the parameters of someone else's computer and to correct errors.

The need for system monitoring

Applications that can be used to diagnose the system are required to obtain important information which will help:

Determine how much memory is installed on your computer, its type and number of slots. After that, it will be much easier to choose a new suitable RAM or conclude that it is worth replacing the entire motherboard or computer (laptop);
Understand exactly how to prepare for the release of the expected game - add memory, install a more powerful processor, purchase an additional hard drive or video card;
Determine the temperature of the GPU and CPU, identifying the need to replace thermal paste;
Find out why they don't work installed programs and the computer freezes - due to wrong drivers, lack of video memory, or hardware failure.

CPU-Z

The free CPU-Z program has a simple interface and allows you to get technical information about almost all elements of a computer:

Processor (including its model, architecture, socket, voltage, frequency, multiplier, cache sizes and number of cores);
Motherboard(brand, model, BIOS version, supported memory types);
RAM (volume, type and frequency);

The main advantages of the application is the ability to get detailed and exact information in Russian about all components of the system.

This may be useful for professional users and lovers.

Among the minuses is the inability to determine the temperature of the processors.

Speccy

Another free program allows you to get details about all the main components and software, from the processor and board, ending with RAM and optical discs.

In addition, with Speccy you can get data from temperature sensors by finding ways to correct connection errors or installation of a ventilation system.

Naturally, the application also determines the number of RAM slots, which can become an important factor in determining the need and possibilities for upgrading the computer.

And when preparing the device for sale, Speccy can be used to quickly compile a list of components.

After all, although the built-in utilities allow you to do almost the same, it will take more time, and you won’t be able to find out some data.

It is worth noting that the developers of the program are the authors of such useful software as CCleaner and Defraggler.

And among its advantages are:

Clear and practical interface;
Fast access to important information
No need to install an application, which may be necessary, for example, if you do not have access to account administrator;
Ability to monitor the selected parameter in real time by setting it as a tray icon;
Run simultaneously with the system;
Free access.

HWiNFO

Thanks to system application HWiNFO , you can get the most useful information about the system.

And also compare the performance of individual hardware components with template parameters and indicators of popular analogues.

In addition, the program allows you to create reports that can be used to compare performance individual elements PC.

All the information is quite detailed, but it concerns only the equipment - it will not work to find out about the drivers with its help.

However, this drawback is practically the only one, since the application is able to collect data on any devices, including even outdated equipment (for example, IDEs and dial-up modems), old bios and video cards of any type.

In addition, the application can also test processors, memory and disks. The data obtained as a result of the test can be stored in logs.

And you can control individual parameters using the tray icons, which change periodically.

AIDA64 Extreme

Using the AIDA64 Extreme application allows the user to:

Get information about hardware components;
Determine which drivers are installed on the computer and, if necessary, look for their latest versions;
Monitor the temperature of the processor, reacting to malfunctions and correcting them;
Test 64-bit operating systems (for 32-bit there are special version– AIDA32) and equipment using unique utilities;
Diagnose and monitor fan blade speed and voltage;
Save the received data as a document of any format.

Benefits of the program - receiving almost all useful information about the system and computer.

Among the disadvantages are the limited free demo version and high price applications, especially for the domestic user.

Pass Mark Performance Test

The PerformanceTest application is a set of tests that you can use to evaluate your computer's performance by comparing it to other devices.

V latest version Utilities built-in 27 programs, each of which is responsible for determining its category of data.

These include tests for:

Processor (for encryption, information compression and calculation speed);
Video cards (for the possibility of bitwise display of two-dimensional and 3D graphics, animation, compatibility with graphics packages like DirectX);
Hard disk (for writing, reading and data retrieval speed);
optical drives(speed of reading, saving data;
RAM (data access, speed).

The results are saved in most popular formats, from HTML to Word, after which they can be sent via email. e-mail, paste into website code, edit in text editor or print.

And the tests themselves can be imported into the application, adding new features.

The main tasks of PerformanceTest are:

Determination of PC capabilities to compare with minimum or optimal requirements games;
Checking components to troubleshoot hardware;
Assistance in making a decision when updating a computer configuration or buying a new one;
Create your own tests.

Meanwhile, the program is not distributed free of charge.

Part of its capabilities, including the improvement graphics tests, is only available for the variant that you have to buy.

Although the application, which is in free access quite functional and allows you to use a lot of settings.

CrystalDiskMark

Small in size and therefore quickly downloadable from the network, the program was created in order to conduct tests with hard drives any type (HDD or SSD) and with all kinds of interface.

The main parameters that are determined by the utility are the speed of writing and reading.

The result is an extended reading, which is unlikely to be useful to a non-specialist, however, for advanced user and a person who determines what problem your drive has, it is almost perfect.

In this case, testing can be carried out several times in a row, automatically averaging the results.

Windows junk files and windows optimization

During the operation of the computer, garbage information accumulates in the system, which slows down its work. To remove this data, there are many free, shareware and paid programs different quality, although the basic means are uninstall Windows. System acceleration is achieved in the following ways:

Removal extra programs. Unused programs take up a lot of space, especially when there are too many of them. The standard uninstaller usually does a good job of removing programs, so it's enough to monitor the state of the memory and remove garbage from it. In versions prior to 8, the system does not track the number free space on disk, which can result in insufficient paging file size. This problem will lead to slow work computer.
Autorun limitation. At the time of loading the operating system, the system processes and programs are gradually added various programs, user-installed. An inexperienced owner of a personal computer accumulates so many such programs that they seriously affect the system boot speed, especially on office machines. When configuring the autorun settings of programs via msconfig utility, which is valid in all Windows versions, you can safely turn off autorun of all non-system applications, except for antiviruses, this will not affect stability in any way, but it will greatly increase performance.
Freeing up memory. Special programs - services - are constantly loaded in the computer's RAM. Some of them are responsible for system functions and is a guarantor of the stability of the system, but besides them there are those that can be safely disabled. It will lead to release additional memory, which will be used to speed up bulky and resource-intensive applications. Some services are installed with third party applications, and can also be disabled. With fine-tuning, you can set it to start manually, when such a service starts at the request of the application, and does not hang in memory all the time.
defragmentation hard drive and fixing errors in permanent memory. Simple service Windows utilities quite enough to reduce the time of reading information from the hard drive and get rid of errors on it. The main thing is not to forget to analyze once a quarter.

Performance gains can be up to 50% if Personal Computer has not been serviced for a long time.

There are other performance secrets that not everyone knows.

Most users use the default operating system settings. These parameters provide good visualization, but at the same time significantly reduce the performance of the computer, taking some of the resources CPU and video memory for drawing and displaying effects and some other functions.

Some users beautiful effects just not needed, but someone does not use the most powerful computer, resulting in slower performance. There are several proven ways to increase system performance.

Setting up visual effects

The operating system is initially set to beautiful appearance, but this increases the load on the hardware of the computer. At the same time, the execution of other, basic tasks slows down, especially on legacy systems.

To fix the problem, it is enough to turn off most of the effects, leaving only the most necessary ones. In Windows 7, you need to enter the control panel, then open "system and security", click "system". On the left side of the window, click on " Extra options system", then select "System Properties". On the "Advanced" tab, find the "Performance" box and click the "Options" button.

You can manually uncheck unnecessary effects, such as "fading" or "shadows". If there is no desire to mess with the list, in the upper part you need to select the "Provide best performance". After applying the selected parameters, you need to reboot the system.

Speeding up your hard drive

Hard drive, aka hard drive or hard drive, contains large arrays of data, to which operating system constantly refers. For searching desired files it takes time, and in the event of a cluttered disk and data partitioning, the slowdown will be seriously felt.

First of all, you should remove unnecessary programs, movies and music. To do this, in the control panel, select the "Uninstall a program" item. Unnecessary files can be found and deleted manually by holding Shift to bypass the trash. You can also use CCleaner utility from the developer Piriform.

After removal, the disk must be defragmented. To do this, double-click on "My Computer", select the disk, right click mouse open context menu and click: Properties - Tools - Disk Defragmenter.

Acceleration of launch by regular means

A large number of simultaneously running programs when turning on the PC increases the user's waiting time. To configure, you need to enter the control panel, open "System and Security", then select "Administration" and click "System Configuration". In the "Startup" tab, select and uncheck unnecessary applications. You can only leave antivirus program. There is also a "Download" tab, where you need to select "Advanced Options". Here you need to specify the number of CPU cores, which will allow the system to boot faster, using all the hardware capabilities of the machine. After making changes, the system will ask you to reboot.

System registry

Manual cleaning of erroneous registry entries is a tedious task that also requires serious skills. When wrong actions, OS reinstallation is guaranteed. To do this, it is better to use the above Ccleaner program. In addition to ease of use, this utility is completely safe.

Additionally, in Windows 7, you can disable gadgets by releasing part system resources for the required work.

The operating system has a rather complex structure. Its work is provided great amount various programs– services and processes. There are many factors that affect the speed and performance of a Windows 7 system. This article describes how you can increase the speed of your personal computer.

The physical part of the computer (processor power, amount of RAM, solid state drives) is not considered in the article. Obviously, the better the PC, the more tasks it can solve, and the faster it copes with them. This guide describes the process fine tuning system, which will bear fruit on any hardware.

General information

To begin with, it is necessary to analyze what exactly affects Windows performance. The guide covers only those factors that can be influenced by any user without help from computer specialists:

defragmentation

This feature allows you to increase the speed work hard disk and therefore the entire computer. Via special utility the system sorts all the information on the media, optimizing the path of the read head.

Over time (as a result of deletion, new files, copying and editing), the data becomes fragmented again, and the process must be started again.

Defragmentation is performed as standard means Windows and using special programs third party developers. Also in the OS, you can set up a schedule for regular operation at a convenient time for you.

Note! Only needs regular defragmentation HDD(HDD). Solid-state (SDD) from such a procedure only wear out, without receiving any increase in performance.

swap file

The function of the paging file is to compensate for the lack of free RAM on the computer. Part RAM content transferred to the hard disk, freeing up space for tasks of paramount importance. If you have many installed physical memory, for example, 16 or 32 gigabytes, it makes no sense to carry out these settings.

To increase the swap size in Windows, you need to do the following:

Performance settings

V Windows settings there is a special section dedicated to increasing computer performance. How to open it is described in the previous section of the manual.

In addition to setting the swap volume, users may be interested in the following options:

autostart

If you want to reduce Windows boot time and improve performance, it is recommended to disable unnecessary applications from autorun. For example, if you rarely use Skype, you can cancel it automatic start at the same time as the system starts, and turn it on only when necessary.

You can manage autorun in the configuration menu of the applications themselves. In torrent trackers, clients for cloud storage, instant messengers and other utilities running in the background, there are special item in settings.

But it is much more convenient to work with a single list for Windows:

Registry optimization

To avoid any inconsistencies in the registry, you must correctly install and remove all applications. If you still have problems, please use CCleaner to clean the registry of "garbage" and bring performance back to its previous level.

Let's assume that we have a working PC in which . We are faced with the problem of restoring the operating system. The system is dead - long live the system! Perhaps this is how you need to think at this moment and not panic.

Panic in case of failures in the operation of the operating system is one of the main reasons due to which sometimes they lose not only the operating system, but also their precious data.

Don't panic, don't make hasty decisions. First, you need to think carefully. And act according to the developed plan.

Why do we often make bad decisions? This is from the field of psychology. It is very difficult for a PC user who is accustomed to the trouble-free operation of a computer to realize that his faithful friend and assistant suddenly refuses to work. This is sometimes seen as an unfortunate misunderstanding. It seems that here a little more, and the problem will be solved. I do not want to believe that before our astonished eyes arose new problem, and now it is not the computer that will solve our problems, but we will solve the problems of the PC.

Winged expression V.S. Chernomyrdin: “Well, this has never happened, and here it is again” refers to the problem of failure in the operation of the operating system.

So what do we have "again"? What do we have when the operating system fails?

First- the system can still be a little alive! And she herself will offer us to restore ourselves to a state of some more early time. At that time, the so-called operating system restore points. These points are created when updates are installed to the operating system, as well as during some other system operations.

Then the PC user can choose the closest in time (the best is for yesterday or even today, but this is extremely rare, only if you are very lucky!) Point of recovery of the operating system, specify it in the menu and run the recovery program and then boot the operating system .

The operating system will be restored to the date and time specified in the restore point. As a rule, user data is completely preserved in this case, or they are preserved in the form they were at the time the operating system restore point was created. V last case you need to take care of restoring user data from the corresponding .

Second – operating system distribution. If the system is licensed, then, as a rule, it comes with installation discs- with the distribution kit of the operating system. With their help, the system can be restored.

But here it is important to understand two nuances:

The operating system distribution kit can restore the operating system to the way it was when you bought the PC.
The distribution kit of the operating system can restore the operating system, saving in it all the changes and additions that have accumulated during the operation of the computer.

How to find out about these nuances? By booting from the distribution of the operating system and looking at the menu that offers a bootable software. If this menu has the option "Restore ...", then this is much better than if there is no such option.

The second (restoring the operating system) is much better than the first(repeated initial installation systems). Since in the case of restoring the original state of the operating system (as when buying a PC), we lose all the accumulated changes and additions, as well as user data “acquired by overwork”. This will cause a lot of additional problems.

Further, we must remember that in some cases, reinstalling the system from the operating system distribution kit can lead to the loss of user data, “acquired by overwork”. For example, if the data was stored in the My Documents folder included in the distribution kit of the operating system.

So, from the distribution kit of the operating system, you can restore the operating system without loss and, in some cases, even save user data. Is it possible to restore the operating system to its original state. It is possible that when restoring the operating system, we will lose all (or some) user data. Then, after restoring the operating system, you need another user.

And if there is no operating system distribution kit? Some PCs (especially laptops) come without a distribution, but on their hard drives in special invisible hard The disk contains operating system recovery tools.

Such a recovery from a special partition on a PC (laptop) hard drive, as a rule, guarantees the restoration of the operating system at the time of purchase. That is, all subsequent changes to the operating system and all user data are likely to be irretrievably lost.

They will need to be further restored. Well, not so bad! By at least, the computer will work again, black or blue screens change to normal Windows splash screen. Further recovery user data is a matter of time and technology.
