I had a similar situation to the one you describe fkalich and it was the power supply fkalich.
If you have a spare pc try the supply from that connected to the minimum amount of hardware you can to boot up ie mobo, RAM, main HD with OS, and video - temporarily remove any other card (firewire, audio, USB, fans, etc). (BTW although my server runs with a 550W supply I tested it with an old 300W supply - you don't need a brand new supply just to check - one issue you can have though is the pin orientation/number on some mobos and supplys. ). Also on power up a pc will try to go through its POST check here and here (you may hear a series of beeps) and these can tell you if you have an issue with video, hard drives etc. If the power supply is dead/dying it probably will not even get this far though since there won't be enough juice to get to this stage. Some mobos have status indicator lights and if yours has one it can again give an idea what the fail condition is. When my supply went though half the time it couldn't even do this - not enough supply to the mobo so the one time it would have been useful it wasn't . Worst case scenario is if the supply is good it may be your mobo that is fried. If you need to check this hook your current supply up to a different pc's mobo. Seems unlikely though as usually you'd need to short out the board/get hit by an electrical storm to fry it. Best of luck.

This may be a trivial question fkalish, but have you checked the power outlet for any voltage drops?

Does it have a Dell proprietary power supply or a standard ATX one? Check the mother board for swollen capacitors as...

I'm neither a Harvard nor hardware wizard but I had the exact same problem with a laptop. I could run for a minute then died. If I tried again it died immediately. Waiting an hour I could get it to run for a minute again. Next time, dead.
Maybe you're second to Harvard and already tried tried this but I solved my problem by a good clean. Especially the fan which was clogged up with dust was the reason it died as soon as it got the slightest bit warm, or if it's some kind of self test that will turn it off when the fan is not working properly. -------------------- My bands homepage
