Motherboard Fried?

[PhoenixKnights]

Hoping someone here can help me out. I was typing in a forums much like this one on a webpage, and all of a sudden my computer just seemed to turn off. Since that time I press the power button and no fans turn, nothing turns on except the little red lights my ram has on it, so I know at least there is a little power going to the motherboard.

I didn't smell any smoke or electrical burn out type smell when my computer died on me. Any ideas what it could be?

Here's my setup:

500 Watt cheapest PSU I could find (I know that's a bad thing I was already planning on replacing it)
P4 2.8 GHZ running at the stock 2.8
2x 512mb Geil ram
ATI 9700 Pro AGP card

The CPU is water cooled with a swiftech water block and a danner magdrive 3 pump, and a heater core as the radiator with 2 120mm fans blowing through it (the radiator)

Do you guys feel it would be the motherboard? or the PSU? perhaps the CPU? let me know, thanks guys.

Well..did you try everything you can? such as replace a PSU, Reset CMOS, removing parts etc to check?

If you haven't tried any basic trouble shooting, or without more information, it will be hard for anyone to offer advice? RAM light comes on, any beeps from the system speaker?

well I don't have an extra power supply, I'm getting one sent to me but it will be friday before I get that. I have tried resetting the cmos and tried other such basic trouble shooting steps to no result, the machine stays cold.

If it was a problem with the CPU would the fans in the power supply go active like they normally do when you turn on the machine? Or would they stay dead as they do now? Tonight I will remove all parts of the machine except for the processor ram and motherboard and see if I can get it to do anything.

You could try a couple of simple tests, you could try measuring the volatge of lines on your power supply, make sure it is putting out power.

Quick check between the CPU and Motherboard: Try pulling the CPU out completely. Then what happens does system speaker admit and beeps? Generally if your motherboard powers up and admits the error code for no processor, then your CPU is bad, if it still does nothing, you are back to either the motherboard or powersupply.

Good point, I think I'll probably try that. I just hate to re- artic silver the thing again. Thanks for the responce.
