Unexpected Power Failures

kingnothing95 · 04-11-2009, 07:19 PM

I have been having a recent problem with my pc. I opened my case a few days ago to clean the dust off some fans and out of the bottom on my tower. Since then my pc doesnt want to stay on, it powers on ok it will load up to my desktop all programs seem to be running fine but this only last for a few minutes. Then my pc just turns off completely, it doest show the "windows shutting down" at all, it just powers off and the screen goes blank without warning. To me this appears to be a possible power failure in my power supply but then again I was also considering it being an overheating problem in the cpu or something, although my pc doesnt seem to stay on long enough to over heat itself. Ive checked all wires and plugs to ensure nothing came unplugged while i was cleaning it. So I am completely and utterly stumped on this problem any pointers or info on what i might be able to find out what is causing this problem.

If you can keep it on long enough to get to the bios setup menu, check the temps and voltages in there and report them back here.
