Shutdown  Last response: in Systems   I built a new computer
this weekend, and it was going great for a while. Installed
Windows 7 64-bit, installed some apps. Ran prime95 for about an
hour, system stayed cool. A couple hours later it just started
dying with no warning. It can happen in the BIOS setup screen,
so I don't think it is a software issue. System now usually only
stays up for something less than five minutes.  Bought some
components at Newegg, some at the local Fry's. Everything is
brand-new, except the CPU which was a customer return at Fry's,
and a USB wireless fob. Not doing any overclocking.  Newegg
