Re-installing didn't help. I downloaded the latest nVidia drivers, removed the ATI adaptor drivers, downloaded the latest drivers from ATI and reinstalled. Works properly now. All hardware was just purchased and the drivers supplied were out of date. Here are links to the drivers: Download and install the latest drivers for your Nforce2 motherboard chipset from http://www.nvidia.com/content/drivers/drivers.asp Be sure to follow the below driver installation hints. http://www.nvidia.com/object/driver_installation_hints.html Download updated video drivers from the ATI website: http://www.ati.com/support/driver.html Go to Add/Remove Programs in the the Control Panel, and uninstall your current ATI video drivers. Reboot your computer after uninstallation. BEFORE attempting to install the updated drivers, obtain both of the ATI Maintenance Utilities and run them. This will ensure that all traces of previous ATI video drivers are removed. http://www.ati.com/support/drivers/misc/catalystutils.html After running the above utilities, reboot your computer. Install the updated video drivers once your computer is finished rebooting.
