OK, My computers been working fine for about 9months, when all of a sudden my computer shuts down and the power goes off. I tried to turn it back on but nada, no power. I smelled something burning for few minutes before the computer shut down. So i thought the ATX power supply was fried cuz i can smell the burnt smell from it. So I bought a new ATX power supply and i plug it in, but when i turn on the power i see a large spark in the new power supply and no power, I think it's fried. I just spent $23 on a new power supply and I didnt even get to use it. The voltage was on 115 and everything was plug in fine. I have no idea what the problem is. Can someone plz help
