Re: Graphic Card Problem
Did you install the motherboard chipset drivers?
It could be a problem with the video card bios. I once had a video card that had a defect in the original bios and the only drivers that would install had to be the ones put out by the video card manufacturer. They did release a new bios for it, but it was a brand new just released to the public card.
I've also seen a few cards act similarly just before they died.
And it might be a power issue, I wouldn't expect it to be but I seen stranger things happen.
