just bought a new antec case. switched over my components, turn on the computer, and all i hear is a loud, high-pitched sound coming from my power supply. after 15 minutes the sound goes away, the computer turns on (case fans, and cd-rom LEDs) but the computer doesn't post. i hooked up my old powersupply, and the computer turns on again (fans, etc.) but no post! juice gets to the fans even without me pressing the power switch, it's as if the mother board is by-passed and the computer powers up just being plugged into the electrical outlet.....what the hell is going on!?!?
