I am working on a computer that the power shut off completly and randomly. I first replaced the motherboard, then the power supply. It still shuts off. I had it on for hours then out of no where, a complete power off. To get it to boot again, I have to unplug the power cord from the back for about 15 seconds. When I got it going again, I took the back of my screwdriver and gently tapped the cpu fan, and whamo, the same power off effect. It seems as if the processor would be bad. Any comments or ideas? Monitoring the cpu and system temps, they seem fine. I will try a new/different cpu, but any input would be appreciated.

is the heatsink on the right way around....i remember building a pc once and installed everything ...just a run of the mill build and had a similar prob.... when someone suggested to me the heatsink was on the wrong way I immediately dispelled it....but it turned out it was! easily done...it seems that it is a thermal prob from what u r saying...so all i can suggest is u go back to basics by troubleshooting and rechecking simple things.
Yes, I double checked everything again tonight, same thing. The temp seems fine, I will try the spare processor when it arrives, If it still does it, then memory, I guess. I tried moving the ram around, and tested it with memtest86, but it seems fine..
Yes, I only have the cpu, power and memory plugged in at this point. You need memory to operate the computer, it will not run without it. I also have unplugged all the switches from the case, I jumpered the power on, so I could turn it on via the power supply, same result. It simply has to be the cpu or memory. I'll try the cpu when it gets here. I'll keep all interested updated..
