have you ruled out the cpu?
One of the things that made me think it was the cpu was:
after I replaced the mobo, my problem changed where the system would power up and turn off after 1 second, but when I removed the 4-pin (2x2) intel mobo power connector and then it stayed powered on but still no video what-so-ever. I switched the MSI K8N Diamond plus mobo with a BFG nForce 4 Ultra mobo.
