Just building a new machine and I have bought the "Abit AT8 ATI RD480 Crossfire" m\b.
When turning on it sounds 1 long beep and then 3 small beeps and then auto turns off. Any ideas?
Thanks in advance.![]()

Have you got the Shadow card in the slot nearest to the heatsink?
have you got all power connectors on the motherboard connected to the PSU ?
Have you got the CPU fan connected to the correct header on the board, some boards will shut down if they can't get an RPM signal from the CPU fan or if the speed of the fan is too slow. if in doubt of the fan being faulty plug a known fast fan into the CPU fan header.

Yes, but not for 30secs - I will try it for longer! To active the CMOS clear do I need to power up while the CMOS jumper is in the clear position?
