So normally when I boot my PC, the fans spin up real fast, then slow down, then I get the single POST beep. Tonight, I tried turning it on, and the fans spun up to maximum, but then would not spin down and it did not post. I changed nothing. What could the problem be? I pulled my X-Fi Xtreme Music out and it then booted. This leads me to believe it is the power supply. Here are the specs: Corsair 520HX (520W) C2D E6750 conroe 3 HDD gigabyte p35-DS3R 4 1GB sticks RAM Gigabyte P5E 8800GT Wireless Card 1 DVD burner 4 fans + HSF fan does this sound like it's not getting enough juice? It worked fine since I first built it... EDIT: I replaced the X-Fi and it boots fine again... electrical gremlins?
