No signal on display when putting in new graphics card.

When I plug in my old 7750 my display lights up again, but when I put in my new graphics card and put all the external power connectors. Then connect hdmi and dvi the displays both say no signal.

  1. What are your complete specs? Mobo, psu, cpu?
  2. If you are connecting everything right that is power to the card and so on then it is a good possibility you got a bad card.
