While i was building a computer, i decided to give it the first power test, while only having cpu, mobo, and ram installed. At the first go it was ok but no sound came out. im not sure i put all cables (the pwr sw, reset btn, the small cables) the right way. later on when i did fix the sound, the mobo started giving off smoke. now the light turns on then instantly off. PLZ HELP (if you need more info, ask)
