Are you sure the card is seated properly?Have you tried the card in a different computer?
WHat is your PSU? brand? model? try re-seat the card or try your card in different PC, if the same problem appears then you got a DOA card, RMA it...
Solved it, drivers did not install, i thought they had. Its working now.
