Black screen with new graphics card.

I bought this computer, a new GTX 650 graphics card and an 850 watt PSU. I got everything installed, turned on my computer and just got a black screen. Any ideas what the problem is?

Nope.

EDIT: Problem solved. Turns out all I had to do was change a setting in the BIOS.
