The first thing to do is to understand why this error occurs. As a rule, solving this issue will already half the task for the user. In principle, you may encounter the fact that the computer unexpectedly rebooted or an unexpected error occurred at any time while working with the operating system. But there are several most common cases.

- After installing any programs, games and applications, the computer unexpectedly rebooted or an unexpected error occurred. As a rule, it is worth waiting for this kind of PC behavior if the installed content is downloaded from unreliable sources, or there is a risk of infection of the operating system.
- Infection with viruses. If your computer reboots unexpectedly or an unexpected error occurs (Windows 7, 8 or any other version of the OS), then it's time to think about whether there is any infection in the system. Only after that it is worth starting to solve the problem.
Reinstall
This message may appear during reinstallation of the operating system. You need to start from this moment, since, as already noted, it most often occurs among users. Did the computer restart unexpectedly or an unexpected error occurred? What to do in this situation?
There may be many reasons for this kind of PC behavior. And you should understand why this message was issued. But, as a rule, system administrators advise you to go one tricky way - working with the registry of your machine. Quite often, this method helps.
When the computer unexpectedly rebooted or an unexpected error occurred, press Shift + F10. A command line will appear. In it you need to register the regedit command. Then you should go to the address HKLM-System-Setup-Status-ChildCompetion, find the setup.exe parameter and change its key value from 1 to 3. Now you just have to close the command line and restart the computer. Everything should work.
Recreation
Did not help? Then you can try to delete and recreate the partition on the hard drive where the operating system was installed. You can implement the idea using the Windows installer itself or through special utilities.
If you do not want to deal with this process for a long time, and the computer unexpectedly rebooted or an unexpected error occurred (Windows 8 or any other version of the OS), then it is best to use the installer. In this case, you need to click in the installation window at the stage of selecting the "disk setup" section. A window pops up where you can do editing. Deleting a section is done by clicking on "Delete section". "Create Partition" appends a new cell accordingly. 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
True, it is not always so easy and simple. Often, users are faced with the fact that the computer unexpectedly rebooted or an unexpected SSD error occurred.

Most likely, your hard drive itself is faulty, and it is hardly likely to be repaired. So, only a complete replacement of the component is possible. After that, all errors should disappear. This option is not the best, but effective. Immediately after replacing the hard drive, it is recommended to change the setup.exe parameter in advance from 1 to 3, as described previously. This technique will protect you from unnecessary problems with reinstalling the operating system.
Applications
But what about those who come across a message about errors or restarting the computer while working with the operating system? There are several moves that can help, but rely on them is not particularly worth it. Especially if you do not have knowledge in the field of computer diagnostics.

In addition, you can try to roll back the system at a time when you were not worried about errors and malfunctions. It is best to use standard Windows tools for this venture. A few minutes of waiting - and the problem will be solved. Only suspicious applications still need to be removed.
Ambush viruses
