PC not detecting New Video Card. HELP!

[sumlit]

I just upgraded from a 8800 gts 512 to a 465 gtx, but my machine is not detecting it.
Doesn't show on device manager. Card is on with fans and all, no error message.
my motherboard is a XFX 780i
What can i do? Help!

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...
