I am trying to setup a system with a Biostar K8M800 to work with a Athlon X2 BE-2400. When I power on, the fans and hard drive will spin, but there is no display, no beep, no post. I tried an Athlon64 4200+ and it works fine on the K8M800 so I'm not sure whats going on. I tried updating the BIOS but that hasnt made any difference.
