once you know which card you're using, either geforce nvidia, or Ati, then here are the sites to go to:
http://www.nvidia.com/object/winxp_2k_81.85.html
or for Ati, go here:
https://support.ati.com/ics/support/...e&folderID=293
If your card is an ATi card, before downloading and installing the driver, you MUST go to windows update first, and download ALL the .net software, from the software optional tab, it comes in two parts, so download the first section, then go back to windows update to download 2nd, then go to ati and download/install driver, otherwise the ATi software will not install/work correctly
