This really is my fault, and I was careless, so I can't blame anybody, especially my daughter.

I had spliced a cold cathode wires that was hooked up to my psu and extended the wires to put it under my desk. During a trip out of the room, my daughter somehow got under there and brushed against the wires and they touched (Yes, so stupid not to have them taped, I know). When I came back in, my PC was off and my wife told me she had saw my daughter go under the table. I looked under there and noticed the wires had come undone. What is weird is that the power switch to the cold cathode was off at this time. Maybe it wasnt the cold cathode wires touching?

Anyways, after initial testing, I attempted to power the board with a different psu, because I figured that would be the first to go out since the light was connected to it. Motherboard would not spin up at all. I jumpered the green and black wire on the old psu (that was in the case when this happend) and it came right on, powering everything that was connected to it. IS it possible for something connected to the psu directley to short circuit the motherboard and not the psu?

I figured the psu would have popped a cap or something. There is no visual signs of burn or popped caps on the motherboard either. I have a voltmeter, where can I check for power on the mobo?

any help is appreciated!
 
That didn't work

I took everything out of the pc, took the mobo out and sit it away from any metal. Only thing I left in it was the cpu/fan, 1 stick of ram. When I power it on, I get nothing, when I flip the psu switch and try to power again, the cpu fan will spin for maybe half a second.

Im guessing the mobo is fried.
