No game that requires Directx 8 or higher will run. I can not get a satisfactory Direct3d test in Dxdiag, it always has an "Error Line 5" etc.
I have tried updating M/B bios, and every driver I can find. I am running Win XP Pro and have installed SP1. I didn't have these problems in Win ME.
Okay, I tried all that stuff. Latest and greatest af all the drivers. DirectX 8.1b (big file!) and re-seated the card,still the same problem.
Specifically, in Dxdiag, test direct3D, it runs directx7 interfaces fine, but when it tries to run directx8 interfaces I get the following message.
Dirct3D Test Results: Failure at step 5 (GetDeviceCaps): HRESULT = 0x8876086a (3D Not Availabe)
I did have an odd problem with my TNT2 that it just suddenly stopped working last christmas (I hadn't installed any software or done any hardware changes in weeks). But nothing with directx would work- trying to play a movie would lock my PC up, websites with activex would lock my pc, hell, even dxdiag would lock my system up. Dropping the AGP aperature to 4mb fixed it, though I had (and still have) no idea why. I was able to raise it back to 256mb when I got my Ti4200...
