Finding and fixing problems in Windows 7. Checking system files for errors. Description of standard damage errors

). In this case, some begin to worry and look for all sorts of reasons and ways to eliminate freezes.
I will not repeat myself and write why this happens, because... The article is not about this and I have already given a link to solving problems above.
I'd rather show you one interesting way, which will help check the system for errors.

Few people know, but in Windows OS there is one useful “little thing” that can search And correct errors in the system itself. Moreover, it will not touch third-party programs, but will only check its system files. This is useful and interesting because many do not think that the reason may be hidden in the system itself, but feverishly begin, and so on. All in all . Yes, this is useful and can lead to good results, but with all these actions it is good to remember what I will write about below.

I already wrote a little about this function in the article, which can also arise due to a failure in system files, which are often forgotten. But still, within the framework of this article, I will repeat...

So, let's run:

and enter it into sfc /scannow:

For those interested, here is a description of the command and keys.

sfc
Where:
/scannow – immediately scans all protected system files.
/scanonce – scans all protected system files once at the next system boot.
/scanboot – scans all protected system files at every boot
/REVERT – Sets the initial parameters to default.
/ENABLE – Enable normal operation of Windows file protection
/PURGECACHE – Clear file cache and check files immediately
/CACHESIZE=x – Sets the file cache size

In the command line (Start -> Run -> cmd) we write the command sfc / and the desired key.

After the check is completed, the system will report the results and ask you to reboot.

That's all I have. Thank you all for your attention.

Unfortunately, Windows 7 does not always work stably, and regularly appear, the system may spontaneously reboot and even force shutdown to prevent damage. In this article we will talk about eliminating system errors on Windows 7.

Description of the problem

As a rule, system errors do not occur without reason. In practice, it looks like a computer or laptop running Windows 7 spontaneously stops working, reboots, or displays blue screen death. In any case, it is impossible to work normally in this mode, so the problems must be eliminated. If you recognize your situation from the description, then this article will help you solve the problem. All system problems can be divided into two large categories:

• The OS no longer starts;
• Windows 7 can start after reboot;

Neither the first nor the second situation are good symptoms, but solving the problem, if the OS does start, is a little simpler.

The computer has rebooted but still starts

If a system error manifests itself as a computer reboot, then congratulations, you are in a better position than people who are faced with the situation that Windows 7 does not start. In this case, the problem may lie in the following:

• Outdated drivers;
• Lack of the latest OS update;
• Errors on the hard drive;
• Problems with hardware;

After the next system reboot, run the registry cleaner. It could be, or any other analogue. Fix any registry errors and clear up free space on your hard drive. You can help your HDD and OS performance a little more - defragment it or use special software to check the disk for possible problems.

Go to the update center, check if you have installed latest updates OS. If you have a pirated version of the OS, you still need to take care of OS updates. You may need to worry about activating your system to get the latest updates.

Problems with hardware - video card, processor, etc. can also cause a reboot. These problems are not truly systemic, since the system here acts as a fuse. For example, if your video card overheats, the system reboots to ensure the safety of the card. Here it is necessary to carry out diagnostics, measure the temperature on the main components. And if the system gives you a blue screen, then look at the error code. If you have problems starting the OS, then watch the following video:

Windows 7 keeps crashing

The term “Windows 7 crashes” means that the system constantly reboots itself. The frequency can be anything - from 1-2 times a day, and up to 1 time in 5 minutes. In any case, it is impossible to work and the problem needs to be solved. This behavior of the device clearly indicates that you have a system error or some kind of hardware problem. If you put potential overheating problems aside, you can concentrate on system errors.

In a situation where Windows 7 constantly reboots, try checking the registry for errors first. To do this, use CCleaner. Then defragment the disks, and at the same time check all disks for viruses. If the problem persists, you can restore to a date when the problem did not exist. System Restore helps in most cases. But sometimes drivers solve the problem or latest updates OS.

Please note that Windows 7 must be kept up to date. If you haven't updated your OS for a long time, then the reason why Windows constantly reboots may be outdated version the system itself.

Windows 7 won't start

The situation when the OS stops starting seems hopeless to some users. How to solve problems if the OS does not start? There are several possible solutions.

After numerous reboots if the OS starts unsuccessfully, the system itself will prompt you to start in safe mode or boot the OS with the latest working settings. Try the latest working configuration first.

If the last working configuration did not help you, then try starting in safe mode. If the OS boots in this mode, then all is not lost. Go to the system utility section and restore to the last restore point. Then restart your computer. Alternatively, you can start in safe mode with support network drivers and conduct a remote system check.

System Restore

You can restore the system without booting it. To do this, when starting the OS, press F8 on the keyboard. A dialog box will open in which you must select “Repair your computer.”

In the window that opens, select the appropriate recovery options and then follow the onscreen instructions. Depending on the problem, recovery may take up to 1 hour. If you have an installation disk or USB flash drive, then you can use them to restore the OS. In any case, follow the system instructions and even a beginner can cope with the recovery.

If the restore does not help, you can return to the “Repair your computer” window and undo all changes. To do this, select the corresponding menu item of the same name.

Reinstalling the OS

The most radical method, but it saves in 100 cases out of 100, if your hardware is not broken, is reinstalling the OS. You can install the OS either from a special installation disk which you should have done in advance. If there is no such disk, then you can download a clean image of the system and separately drivers from your manufacturer on the Internet. We will discuss the issue with the license, how to transfer and save it, in one of the following articles.

We hope that your Windows 7 computers and laptops will run smoothly and you will never encounter system errors. And if you do, now you know how to fix OS errors.

The appearance of errors in Windows 7 becomes an insurmountable problem for inexperienced users. However, absolutely all software errors can be easily corrected yourself, without turning to specialists for help. Let's take a closer look at how to fix errors on a Windows 7 computer.

Incorrect execution of the program. In some cases, the compiler stops interacting with the encrypted or malicious code, which leads to an error;

Incorrect configuration of these data can cause a huge number of additional errors.
