hmm, I'm not sure how to answer this. lol
The problem isn't with Windows, it's with the BIOS on the motherboard. Possibly with the firmware of the video card, but since it was working fine with BIOS version 16 for a minute, I assume it is a BIOS issue.
I'll check evga and report back if there is a new one and if it fixed it or not. otherwise I'll assume it's a BIOS issue.
