i recently built my own computer and for the first five minutes everything seemed fine. while i was in the process of installing windows xp my whole computer lost power. i tried to turn it back on but all i got was a flash from the leds and a few rotations from all the fans. after that i stopped getting anything from it when i pushed the power button. after some tinkering i discovered that if i didnt plug in the atx12v plug all my lights and all my fans would start, but i would get no video. if i plugged in the atx12v i would get nothing. i think i heard an electrical sound when i hit the power button with the atx12v plugged in, it was kind of a sizzle but only lasted a split second. i have tried just about everything i could think of and everything i could find online. please someone help me.
