I've had some troubles with this computer. At first, it wouldn't start. It ran fine one minute, then I shut down, about an hour later, I tried again and it wouldn't work any more.
I got a new motherboard, and that wasn't it. So I read some more online, finally found some other people that had had the same problem, so I got a brand new Rosewill power supply.
Now it starts, runs for about a second, then shuts down. All the fans start up fast (Power supply, CPU, case) then dies.
Any ideas?

It's entirely possible that the switch in your power button is sticking...I've seen people replace all the hardware in a PC to find that it's the power button that's at fault...
Intel Core 2 Duo E4500/2.20GHz @ 3.04GHz
4GB DDR2 800MHz / PC2-6400 RAM
4TB Total HDD
NVidia GeForce 7600GS 512MB Graphics Card
Antec Nine Hundred Case / OCZ StealthXStream 600W PSU

Should I transfer over to my spare case? I don't think it's the power button, but I could try the other one.
And right now the only thing I have plugged in is the motherboard. So I don't think it's the HDD. And yes, the PSU does die when the PC shuts down.
Where should I look for a short?
Any other ideas? Please, I'm at my wits end.
...as an after thought, would an improperly seated CPU cause this?

make certain the cpu heatsink & fan assembly is properly seated or the cpu will do a thermal shut down. can try the motherboard out of the case with just the psu, a stick of ram, cpu with fan assembly & a videocard if not onboard version.

Hey, thanks for the help everyone.
The problem was that I had forgot to seat the heatsink/fan properly.

Try a new adapter or plug it straight into the wall.

i tried that in the begginig but still i had no change.Could the hdd bring about such a problem? because on a number of occassions, i've heard squicking sounds in the disk before the power collupses.

Possibly. Try to run a chkdsk on the drive or the IBM Drive Fitness Utility.

thanx guys,i think i discovered where the problem was. when the processor is engaged ie running a number of programs, more power is required which in my case the power supply unit couldn't allow through to the motherboard.i replaced it and it's been running fine for a while.

I'm going to place a warning here. Rosewill power supplies are bad news, as are all cheapo brands of PSU, they're often not only poor quality, but dangerous. You should only fit high quality brand units to PCs that use a lot of power (Seasonic, Corsair, Tagan etc.)
