Okay. First make sure your Cables are hooked to the Connector on the Graphics Card and NOT the Motherboard. That happens more times than you would know. If it isn't working, then REMOVE the card and then try the Connect on the motherboard ( Integrated Graphics ). You HAVE to remove the Graphics card in order to enable the Integrated onboard Graphics. If it works, then plug the card back in ( don't worry about the drivers at this point as Windows will use a generic driver ), make sure the power cables to the crad are plugged in. You have to do this, as it will not get enough power from the PCIe slot to drive it.
