Wondering if someone could help me out, I just bought a SOLTEK NF4PRO-939 with an ATRIX case, and AMD 64 3200+ Venice core. When I hook everything up correctly, all my motherboard does is make a BUZZZZ sound right by where the ATX power cord is connected. When I swap power units it does the same thing, when I put my ATRIX 480 watt power supply into another computer in the house it turns on, the fans pins up, and the computer starts. Anyone know anything other then a deffective motherboard that would be causing this?
