so im running xp, and my computer was running for more than 5 days straight, and i got a decent cooling for my cpu. but just this morning, i was playing F.E.A.R. and i smelled something funny, kinda like the burning but nothing was on fire. so since i could smell it from above, Im assuming that it was my PSU's fan blowing the smell away. I have a light up mouse, and the LED on the mouse is on whenever the mobo has pwoer, now it doesn't. So either I have no power from psu or my mobo got fried. The worse part is after the computer shut off, there was a spark and from the glimpse I saw, it was either at or near the ATX connection area, do you think my mobo or psu got fried? I'd rather spend 50 on psu than 200 on mobo. And my psu fan has only 4 inches between it and the wall.
