If the fans are connected to the motherboard and they spin on start, its probably not a motherboard issue. Does your system beep when you start it? (if not, is the speaker/pieso plugged in the mobo) ? What is the behavior of the system when you press power?
all that happens is the cpu fans runs gpu fan runs hdd is running dr dbug on board shows 00 but no bios screen i tried the GPU in a differnt computer and it worked i think its the cpu im going to order a new one today and send this one back to amd its under warranty then ill have 2 on hand or put one in the extreme 3 and other in extreme 4
im getting the same out of both mobos all fans come on and no bios no beeps
