First, make sure the graphics card is properly seated in the PCIe slot.

What happens when you turn the computer off, hook your graphics card up to your display, and turn the computer on?

If you don't get a display, go back to using the onboard graphics and try updating your motherboard's bios to the latest, stable revision: http://www.ecs.com.tw/ECSWebSite/Product/Product_Detail.aspx?DetailID=897&MenuID=16&LanID=0

What's the make and model of your power supply?
 
When you go into the bios, you should be able to see what version you have. So compare that to the bios list, which is in the link I have you.

And I need to know the make and model, or you have to take a picture of this label:
