PC-Games & Internet » PC crashes and reboots during gaming

Hi all,

My computer reboots automatically while I am playing games. I cannot notice any patterns when this happens since on times it happens frequently and on other times not so frequent. Sometimes even when I am in the menu and not using the PC
I cannot find the source and have been trying for quite some time now but to no avail. I tried updating drivers but did not help. Would really appreciate if somebody could guide me on finding the problem and maybe solution to this as it is beyond me.
