Hi I bought a GTX770 and replaced my old GT610, once putting the graphics card in the fans work perfectly fine but when I try to press F9 on my key board it wont let me press any key? I then waited a while then it went to a blank screen with a flashing ( _ ) in the top left corner. I swapped keyboards to a PS/2 then the same happened. When I put my old card back in everything works fine and goes back to normal. I sent it off to the shop where I bought it and I have just had a email saying they isn't a problem with the card.
Does anybody know what the problem is?
