Step 1: I would go to the Nvidia website find your graphics card and down load the latest drivers -
http://www.nvidia.com/content/drivers/drivers.asp go there and enter the required information. Download and Install, and reboot your computer. See if that brings you any luck, if not make sure you have the latest directX 9.0c installed as well. Change the settings in game, if still no luck, you might be able to play the game using openGL instead of directdraw not sure.
