Please make sure you installed before nvidia forceware drivers.....
Download the lastest ones from Via or nVidia (who makes the chipset of your motherboard).......
Via 4-in-1 drivers from www.viaarena.com
nVidia Mobo drivers from www.nvidia.com
Intel ones dont need agp driver as i know...... (but dont have intel chipset for amd processors)
Yeah ill would unistall the graphic card driver from the control panel and reinstall it, it is possible and I have done it myself when iam tuning my settings for pc games I screwed something up, reistalling the driver will default any setting you may have modified that may affect chankast performance.
