I'm not sure if they do or not.. but.. it could be a issue with the Windows 2000. The current games I was attempting to run to test out the machine to see what if anything was messed up are Black & White 2, Vampire: The Masquerade Bloodlines, and Zeus with the Poseidon expansion.
The first two are the only ones I'm having problems with (so far). Being that it's 3D accelerated. Zeus is a pretty old game but it was something to pass the time while downloading.
I have the DirectX 9.0C update and I ran the DXdiag (thank you for that!

). The tests were all fine. The only problem through out the whole thing was one file was not digitally signed by Windows under the display.
I will upgrade to XP if necessary but I really don't want to. Everytime I do that I seem to have a buggy installation.

I've even had other people to do the install and it still tends to be weirded out after a week or so.
I really want to get this fixed before I finish updating Everquest 2. That was my sole purpose in upgrading my machine. (please don't bash me!

)
