My nephew was playing a game on my desktop today, and it turned off completely, power, everything.

I figured maybe the GPU had burned up since it was kind of warm in the room.
But no, with gpu removed it still does not even attempt to power on. No lights, no fans, no beeps. I do however, get a quick flicker of a red light from the motherboard when i hit the power button.

I have also tried removing components one by one and trying to power it on. With only MB/CPU/RAM, Speaker, power switch and a known-working PSU, it does the same thing.

Would it be safe to assume the motherboard is dead? since i cannot swap the components into any other systems to test.

The rig is only 2 months old. I bought the board from newegg as an 'open box' item. last time i do that.

GIGABYE - P55M-UD2
XFX 9800gt
CI7 - 860 (lga 1175)
G.Skill ripjaws (ddr3 16000)
Apevia 600W PSU/ HipeR 580W PSU
 
Which PSU was in there when you had this problem and which did you test that was "known-working"?
 
the apevia PSU was in there. It came with a small form factor case. The HipeR was from my old tower, it was working when i parted out that system.
 
It might be a shot in the dark but both of those are low quality psu's and there is a chance they are both dead. Can you get a hold of a newer psu?
 
i do not have access to any PSU's that have the appropraite +12v cpu power, just some older psu's from the pentium 3 era
 
does the old jumping green-to-black jumper trick work on newer power supplies? I just tried it on both of those PSU's and neither turned on. The HipeR was making a really loud squeeling noise when i plugged it in.
 
sounds like the psu.

*avoid generic like the plague.
