Asus A8V Deluxe + BFG 6800 Ultra = Problems HELP!!

[StormRoyale]

Howdy folks.
I just put together my new system and I'm having a weird problem. I have the Asus A8V Deluxe with the newest bios (1009), newest chipset drivers, Antec True Power 550 and BFG GeForce 6800 Ultra OC, also with the newest drivers (66.93).
Now here's the problem: When the GeForce drivers are installed, the screen gets.... Staticy? But not like UHF. Pixels become grainy and text become illegible. It's kind of hard to describe.
I thought it was hardware failure with the Graphics card, so I had that replaced. Replacing it didn't do anything. Neither has reseating the video card, or playing with the Bios settings. I spoke with BFG tech support and they think it might be a problem with the motherboard. But when the drivers are NOT installed, the picture is fine. Could the motherboard even be at fault? Does anyone have any suggestions or ideas?

If you can, please check the videocard in another motherboard. Would be a defective motherboard or vga...
Wrong pixels or artifacting are often overheat or faulty memory symptoms, like this is happening you at startup -i suppose- i think there is no overheat.

I will try the graphics card in another system, but when I replaced the graphics card I still had the same problem.
