Hi, I have an Asus Crosshair motherboard socket AM2, have AMD FX-62 processor, ATI Radeon X1900XT, BFG?? power supply 650 watts,2 sticks of Corsair XMS2-6400 DDR2 800Mhz memory. Attempted to power up and I get 1 long and 3 short beeps...this motherboard has an LED monitor which reads there is a "CMOS err". I am trying to figure out if its my motherboard bios or the processor. I think the power supply is fine. Could it be that my BIOS is corrupt or not there? Please reply. Derreke one other strange thing....the motherboard CPU fan connector has 4 pinsholes;however the CPU fan wire has only 3 pins..this motherboard/CPU are supposed to be compatable??? does this occur often??
