Looking at the pictures, I know it's not the problem I mentioned above.
Your drivers are WHQL'd, so I doubt it's a problem there. Make sure that your card is fully seated, your RAM is fully seated, and your Processor is fully seated (Yeah, they do make a difference...)
Then, check what speed the BIOS is running your card at. Could be overclocked to a point where it's not stable, but the BIOS thinks it's the factory default.
I know that Windows calls the AGP Slot PCI Bus1, so that's no worries. Mine does the same thing. It's probably a problem with DirectX, so what I would do, is go to the website Fisher posted, and re-do some of the main DirectX Dll's, d3d9.dll, and other core dll's.
Last, but not least, make sure that the DLL's in your C:\Windows\System32 folder are all correct, like, no misnamed DLL's. Don't check all, just ones related to display or monitor mapping/rendering.
