Its been a long time since I used Win2000, but as I recall, the Windows driver signing was not auto matic, which means that any 3rd party software could overwrite Windows drivers. This is an excellent opportunity for incompatibility issues.
Goto Control Panel>System>Hardware and click the "Driver Signing" button. Click on the "Warn" radio button, click OK, close all windows, reboot.
Go back into Control Panel>System>Hardware and click "Device Manager." Click on each component and select properties to re-install the devices driver.
