Uninstall all the old drivers first. Then reinstall the GT210 drivers from the Nvidia website. If the GT210 isn't picked up - there's a setting you can change in the BIOS to use the PCIE card instead of onboard.
Thank you for the prompt reply but biggest problem is that monitor doesn't work even to allow me to uninstall old drivers...I thought that the new card would override and allow me to uninstall the old after start up but can't get that far. Perhaps a faulty new card?
