Pc Restarts and cant find out why

[Guest]

I have looked all over the forum and i cant find a solution to my problem. My
pc randomly restarts without any error message. i have already tryed turning
off auto restart under system properties but that didnt help. I have noticed
that when i press print anywere it will restart, or when i open a disk drive
it will restart. These are not the only times it restarts though. I have done
scans for viruses with lots of different programs and they couldnt find
anything. Please someone help me. Thanks
