what does it mean when you can game, and do everything on your PC perfectly fine at say 4.2 ghz. can run 100 back to back cinebenchR10 quad core. but as soon as I launch prime 95, and start the torture test my computer BSOD's and reboots?

like, thats not the CPU failing is it? Is that a sign that more voltage is needed, the FSB is too high, bad memory, or what?
