Last night I left my computer on when I left for work. When I came home, I found it turned off, I thought it was no biggie, maybe my dad turned it off. But when I pushed the power button to turn it back on, nothing happened. No lights turned on, no fans or anything. I then unplugged everything and opened up the case. I plugged the power supply back in, and tried powering agian. Agian nothing happened. The only light that was on was the standby powerlight on the motherboard. My intitial reaction is that it's a power supply failure, or a power on switch failure. However looking through some other posts on similar problems says there is a chance it is a motherboard issue. What can I do to narrow this down to a single problem.

You can unplug it and let it sit for about 20 seconds until your power supoly discharges. If that doesnt work, its more than likely a mother board issue. Keep me updated.

I ruled out it being a switch, by testing it. I did unplug it for a few hours, and it didn't seem to make a difference. I hope it's not the motherboard. I just got a new motherboard no more than a month ago, because my old one also just up and quite working...

Now your confusing me. What does a switch have to do with it?

heh, well obviously it has nothing to do with it. But I thought that maybe my on/off switch wasn't working. So the motherboard wasn't picking up when I was turing it on.

If thats the case, i can tell you how to rewire the ps so it will turn on but the motherboard is gonna go eventually.

looks like it was power supply failure. I went to a friends and swiped his power supply and hooked it up, and my machine powered up just fine

Wow, i've never seen a power supply failure that did that before. well sorry i couldnt be of much help finding your problem but congrats on finding it youself
