I do not believe that it is wise to try to run that game with anything below a GeForce 6600 (or its ATI equivalent).
By the way ... for XP, the last "certified" nVidia drivers (175.19) were released towards the end of June. I had no problem with them.
Today, I uninstalled them to test the most recent, beta drivers (177.92), which were released towards the end of August. No problem yet.
If you wish to update your videocard's drivers, please go to the Windows add/remove-programs menu, and first uninstall your current drivers (and then reboot before installing the new ones).
Launching the drivers-installer without having uninstalled the current drivers should execute a suitable file-overwrite ... but it is not prudent to proceed in that manner. The nVidia website does recommend to first uninstall.
