Well all I can say that hasn't been said is to remove the card, uninstall the drivers, reboot, install new drivers from the manufacturer's website, reboot, then plug the card in and let it get detected. Reboot again and see if that doesn't help you. Also, you might get into c:\program files and see about deleting the folder that contained the old software after you uninstall it to make sure no configuration files or logs are held over from the old install.
