make sure that you do not have you IGP driver installed or your IGP enabled. Make sure that all of your old drivers are gone. Try uninstalling, and them re-installing drivers. Do you have a friend that has a computer that you can test the card in? Download Driversweeper, and sweep all the DIPLAY DRIVERS ONLY in safe mode. If none of that works, RMA. The error message sounds like it is detecting another card.
