Ok i had to post a completely clueless thread like this but am clueless.... My computer (I just built) just restarts without warning. Here are the specs, Biostar mb (onboard video/audio) 512 megs of sdram. 80 gig ibm deskstar. (any other specs ask becuase i cant think of anything else) Only thing open when it recycled was winmx, and internet explorer. HELP!!! And i checked the cpu temp with speedfan and it says its only around 48 to 50 degrees.
