I am having a weird problem with one of my computers. It keeps shutting off. Then when I boot back up, the bios setting page is up with the cpu frequency multiplier highlighted. It just started doing this. It isn't heat as far as I can tell. The cpu fan is still spinning and i have tried running with a large fan blowing in the case. The system has never been overclocked. Could this be the cpu going bad? I am really at a loss. The computer doesn't reboot, it just shuts off. Very strange. Any ideas?
