|Sounds like the card isn't getting enough voltage to run in "3D mode". The Aero GUI is Direct3D-rendered. |
I used to have similar problems with 3D applications on 440BX boards powering newish cards. Most of the time, I was able to get the app to run by increasing the AGP voltage.
Stuff to try:
-Make sure that your power supply has at least 26 amps on its 12v rail (or 17+17, if it's a dual-rail model)
-Make sure that a 6-pin PCIe peripheral power cable is plugged into the card. Oh, and make sure that it's a true PCIe plug, not one of those PCIe to double Molex (hard drive power) adaptors. I've had problems with those things, especially trying to power high-end cards. If your power supply does not provide a true PCIe power cable, buy a new one.
-If your motherboard has a 4-pin molex connector near the PCIe slot(s), make sure that a power cable is plugged in. These EZ_Plugs, as Asus calls them, assist in powering high-end cards and SLI configs. While my Asus manual states that the EZ_Plug is only required for SLI, it's probably best to have it plugged in--even if you don't have two videocards installed.
-If all else fails, look for the PCIe voltage selector in your BIOS setup. Bump it up a notch.
