Many users complain from time to time that the computer unexpectedly rebooted or an unexpected error occurred. This window can disturb any person while working with the operating system. But, as practice shows, most often it pops up when reinstalling Windows. And at such moments people, as a rule, embrace panic. What to do in this situation? This issue requires special attention.

Cause

The first thing to do is to understand why this error occurs. As a rule, the solution of this issue will already half facilitate the task for the user. In principle, it is possible to encounter the fact that the computer unexpectedly rebooted or an unexpected error occurred, you can at any time work with the operating system. But there are several most frequent cases.

1. As mentioned above, reinstall Windows. Quite often, users note that this problem occurs just when the computer restarts during this process.
2. After installing any programs, games and applications, the computer unexpectedly rebooted or an unexpected error occurred. Typically, waiting for this kind of behavior of the PC is if the installed content is downloaded from unreliable sources, or there is a risk of infection of the operating system.
3. Infection with viruses. If your computer unexpectedly reboots or an unexpected error (Windows 7, 8 or any other version of the OS), it's time to think whether there is any infection in the system. Only after this it is necessary to start solving the problem.

Resetting

This message may appear during the reinstallation of the operating system. It is necessary to begin from this moment, since it, as it was already noticed, most often occurs in users. Did the computer suddenly reboot or did an unexpected error occur? What to do in this situation?

The reasons for this kind of behavior of the PC can be a lot. Also it is necessary to understand why this message was issued. But, as a rule, system administrators advise to go one tricky way - working with the registry of your machine. Quite often this method helps.

When the computer unexpectedly reboots or an unexpected error occurs, press Shift + F10. A command prompt appears. In it, you need to register the regedit command. Then go to the address HKLM-System-Setup-Status-ChildCompetion, find the setup.exe parameter and change its key value from 1 to 3. Now it's just necessary to close the command line and restart the computer. All should earn.

Re-creation

Did not help? Then you can try to remove and re-create the partition on the hard disk where the operating system was installed. You can implement the idea with the help of the Windows Installer itself or through special utilities.

If you do not want to understand this process for a long time, and the computer suddenly rebooted or an unexpected error occurred (Windows 8 or any other OS version), it's best to use the installer. In this case, you need to click in the installation window at the stage of selecting the "disk configuration" section. A window pops up in which you can edit. Deleting a partition is done by clicking on the "Delete partition". "Create section" accordingly adds a new cell. The main thing is to choose the parameters for it. Write the desired volume of the section and save the changes. That's all the problems are solved.

HDD

However, not always everything is so easy and simple it turns out. Often, users experience that the computer unexpectedly rebooted or an unexpected SSD error occurred. And this is a pretty unpleasant signal for users. Especially if you have already tried the above methods of troubleshooting. What happens in this case?

Most likely, you have a defective hard drive, and it is hardly subject to repair. So, only complete replacement of the component is possible. After this, all errors must disappear. This option is not the best, but effective. Immediately after replacing the hard disk, it is recommended to change setup.exe parameter from 1 to 3 in advance, as it was described earlier. This technique will protect you from unnecessary problems with reinstalling the operating system.

Apps

And what about those who have encountered a message about the occurrence of errors or restart the computer while working with the operating system? There are several moves that can help, but you should not rely on them. Especially if you do not have knowledge in the field of computer diagnostics.

As already mentioned, such errors can pop up after installing or using certain applications, games and programs. In this case, you can try to remove the utilities, after which you began to disturb the data "surprises". Often, if you act promptly, the problem will be resolved.

In addition, you can try to roll back the system at a time when you are not bothered by errors and malfunctions. It is best to use the standard Windows tools for this task. A few minutes of waiting - and the problem will be solved. Only suspicious applications should still be deleted.

Viruses in an ambush

But if you suddenly have windows with error messages due to virus attacks, then you need to act immediately.

To begin with, you must promptly try to disinfect the computer and roll back the system. The main thing is not to delay with this moment, otherwise we will have to start immediately to radical measures. It's about reinstalling the operating system. Although, as practice shows, fast work with the antivirus, as well as anti-spyware applications combined with cleaning the registry, have a more effective impact on the error than attempts to "demolish" and reinstall Windows. Doubt in your abilities? Take the computer to the masters. They will help to quickly solve all the problems.
