That is correct. I suggest you to uninstall the current driver you have installed in your system via the add/remove programs, don't let windows restart the computer now if it asks after the driver uninstalling process. Run detonator destroyer available in guru3d.com right after the add/remove programs driver uninstall, then restart. After you computer booted up, search in your c:\windows, c:\windows\system directory for:
If you find any of the above files, manually delete them after that go to your registry and search for any nvidia entry and delete them, close the regedit program and install again the drivers. Also make sure that DX9.0c is properly installed as Kirby said.
Anyways you should wait till nvidia releases any win 9x driver supporting DX9.0c, but personally I don't believe it happening soon.
