1) Do not choose to run the installer from your browser. Download and save it, then go there and run it.
2) In Device Manager, uninstall whatever your graphics controller is currently recognized as (something like "VGA adapter" or "PCI VGA adapter"). Reboot and see if that helps.
3) The drivers may have a minimum service pack level requirement. To see what SP you are on, go to Control Panel, System Properties. The current and final SP for Windows 2000 is SP4; if you are below that, just go ahead and install it now. It may solve your problem and you should have it anyway. You can get it
here.
