What causes a computer to keep rebooting itself?

Answer by  Az (343)

You probably have a virus causing this issue. You'll need to access your computer's boot up menu as your system turns back on (try using F10, F12 or another F key depending on your system), then reboot in safe mode. This should enable you to get into Windows, so you can turn off "automatically reboot".

It is very possible that your computer has a virus of some type. I would suggest running a free anti-virus and spyware software to determine what could be the cause of the issues. Also check that your fans are running as when the PC gets hot it can cause it to shutdown.

Your computer has a serious fault, possibly an overheating problem. Run a virus scanner, and if that doesn't fix it take the PC to a repair shop.

The power supply may be going bad or the memory is loose inside they computer. Listen to see if the fan is turning in the back of the computer if it is not then the power supply is most likely bad. Hope you are able to fix the problem. If not try the Geek Squad at Best Buy.
