Computer hardware/power issue

Alright, maybe someone can help me on here, I know this isn't the greatest place for computer questions, but I have a feeling someone might know something.

I have a comp with power issues. I can be working on the computer, and just going along doing normal stuff, then all of a sudden the computer will just power off and on. When I mean power off and on, I mean the actual POWER, not Microsoft shutting down, but electricity. The computer reboots and comes back up, and it will do this continously. Until finally I just leave it alone. When I come back the next day, works normal, no problems.

I switched the power supply with a known good power supply, same results. This doesn't happen everytime I am on the pc. Will it reboot like this if it gets too hot??? I am wondering if its rebooting when the cpu gets to a certain temp. I am a little perplexed.

Any ideas?

How old it the puter?
Check the CPU fan to verify it's operational. If it is, check for dust in the heatsink and clean w/ air duster. If that doesn't do it, dl speedfan and check the temps and voltages.

The comp is probably 5 years old now. I built in myself back when i cared. The fan is spinning ok. Its been doing it for a couple of years. It's a 50/50 shot it will reboot. I will definitely try out that speedfan link. What temp is too hot for the cpu?

Power supplies go bad, you're lucky to get 5 years out of one. Normally they fade away and gradually put out less and less power due to the way they convert ac to dc. Replace the power supply or remove hardware.

I did swap the power supply, and it did the same thing. That was my first guess too, I am thinking its either a bad m/b or the cpu is getting hot, and the board is forcing the comp to restart to cool it off.

I downloaded the speedfan program, how do you know which temperature is to which hardware?

I think I got the temp issue under control. I reset the bios to factory settings and let the mb decide the front side bus speed. I think I originally set it up manually. It seems to keep the cpu temp a full 8-10c cooler. Maybe that will stop the restarts. Its so random, I wont really know until I just mess around for a while on the pc.

Well as soon as I posted that, I realize why I manually change the front side bus settings. My cpu is a 2.3ghz athlon, and its clocked down to a 1.14ghz now. Hmmmmm, that shit sucks. Any suggestions? Keep changing fsb settings?

Check in the bios and see if cool n quiet is enabled. it will throttle the proc speed.

I don't think thats an option in the bios. I adjusted the front side bus, got the cpu to 1.53ghz in windows. That put it at around 51-53c.

If the proc was made from about 2k on it will have the AMD Cool-n- Quiet feature to throttle it down when not needed to conserve electricity and run cooler.

I double checked this. That feature isn't in the bios. I built the pc in 2003, its not impossible for the processor to not have that feature I guess. Really pisses me off, I don't the full capabilities of the processor. Might be time for another rebuild, or just buy a damn dell.

dl cpuz and run it, then w/ it open do something CPU intensive to verify that you're getting full speed.
