Wulfy, you don't say what make your card is or what version your driver is. I have seen many posts on the Nvidia 23.11 driver, most bad. I have had a problem with that driver (not as bad as yours) and I have changed to 22.50. I have run benchmark tests on most XP nvidia drivers and 22.50 works best for me. Check the web site of your card manufacturer and also as already posted check your 4 in 1 (if you have a Via chipset). Your card maunfacturer should have the latest XP drivers for your card. If that don't work let me know. You can e-mail me @ Zippy@apgaming.com. Zippy
