I have an Abit AN8-SLI with a geforce 7800gt, 2 gigs of ram, and a 3500+. Its powered by an Antec Neo HE500. It's been working since I built it a couple years ago with few issues. I moved it to a different room in my dorm today and it quit working. I opened up the side of the case and turned the power supply on and saw that some of the LED's in the POST code display and LED1 would flash and that was the only indication there was any power. I've checked all the power cords I can find and all the other connections and I can't find anything wrong. Any ideas?
