Hi boredom ,
Windows is set to automatically restart every time the system crashes. Such a crash could be caused by anything including hardware failure.
First step is to disable 'auto-reboot'. After disabling it you should then see an error message on the screen instead of getting a restart.
If so please post your error message here.
Here is how to disable auto-reboot:
1. Go to Start > Control Panel > System
2. Go to Advanced
3. Under the Startup and Recovery section, click Settings...
4. Under System Failure un-check "Automatically restart"
