Ok, so some symptoms.

Out of nowhere it just shuts down. I try to power it back up, and it has juice for 2 seconds, then dies again. Rinse, repeat, same thing. My first thought is the power supply just shit on me, which pisses me off because I spent good money on it.

I walked away for 5 minutes cursing, then come back and try again. I unplug everything but the power first. The power stays on for about 10 seconds this time. I let it sit for a few more minutes, try it again, and it stays running.

So I begin to plug everything back in, turn the machine on again, and while it powers up, there is nothing on the monitor. First thing that goes through my mind now is that my processor fried itself. When my friend and I built this machine neither of us had a properly sized fan, so we had to kitbash something. It's been 3 years now with no issues, but I was always worried about that. I unplug it all again, open the case up, and remove the fan. Asides from some dust, the processor looks fine. I unseat it, and it comes off the motherboard just fine. Doesn't feel hot or anything. So that seems good to me.

My next thought is to reseat the video card. I try that out, and still no video. Kinda stumped from here.


So, major power loss, but eventually it starts to work again. Then no video. None of the hardware components seemed overheated. I'm stumped. What you got?

Internal components of the power supply could have overheated and malfunctioned. That's happened to me before more than once. Once it gets hot enough to malfunction, all sorts of problems will occur, including the 2 second power up, and following shutdown. Then when the power supply is cool enough to actually startup the computer, the damaged components in the power supply restrict adequate power from starting up things like video cards and possibly spinning up drives.

I can't really think of a good way to test a power supply that won't stay lit though.

Power supply or motherboard, either way if it is less than a dual core cpu, I wouldn't put any money in it.
