Recently I got my new GTX 960 gigabyte wind force OC 4gb, and I put it in my pc but soon as I boot up it has the first beep as a successful startup, but then I see my manufacturer's name Gateway and I can't press Bios or boot options. Then 3 beeps happened with a 25-30 second interval between each beep and the last beep takes me to a black screen with a blinking underscore at the top left. Pls help I really don't want this card to go to waste!!
