I loaded Windows without issue, but after installing the video card drivers, I have discovered problems with 3D applications. I have uninstalled and reinstalled the motherboard and video card drivers several times, including downloading them again from the internet. 2D video works fine.
In Flight Simulator 2004, the game will start, but after about 5 seconds, the screen freezes and then goes blank and I get "No Video Signal" on the monitor. In 3DMark2001, both the benchmark and the demo freeze and then go blank after a few seconds of running. I tried an ATI demo as well, and it freezes after a few seconds on occasion. I thought perhaps it was a video overheating issue, so I removed the side panel, but the screen still freezes and then goes blank.
The AGP aperture size is currently set at 128 MB in the BIOS setup. FastWrite is diabled, and I know it is not supported by this video card. It is running in 8x AGP mode. The video card is used from my machine at my house, but it never faltered since I got it over a year ago. Also, there is never any prblem with the 2D video.
I would really appreciate any suggestions or help with what to do. The most obvious choice is to go out and get a video card from a place with a liberal return policy and try to see if that fixes the problem. Does anybody recognize these symptoms?
