Dated June 2001. Remember to re-install your current drivers, do not load over the top. Reinstall by goingg to Control Panel-->Add/Remove Programs (NVidia Drivers) or re-set video adapter drivers to Standard VGA in Display--> settings-->advanced. ReBoot then install 1241 drivers then reboot. Good Luck
