Well, here's my problem. When my PC is under heavy duty (playing demanding games or such) it suddenly restarts. I don't know if its because of the OS or some other kind of error. I've searched on the internet for answers but i never found a working one. Any ideas on how to fix it?

Thank you all for your help.
