>Another thing you can try is to go to Start/Run and type in dxdiag.exe - that will run the DirectX Diagnostic Tool. On it you can go to the Display tab and there will be a button for "Test Direct3D" - you can hit that to see if Direct3D is working on your system or not.

Dont be scared to UPGRADE the Direct X also. This page shows you the version you have. Shoud say at least 9c or something like that!

Also if the reboot doesnt fix it and it was working a week ago, it could be a color depth or resolution setting. Did you change this? (New monitor, etc.) [EDIT]
