GV-N56GOC-1GI Help!

Hi guys, I have recently bought and built a new computer. Everything seems to be working just fine. All except my Graphics Card. When I startup normally, I run off onboard, but then when I connect my Graphics Card, I get no signal!
My specifications are:

Intel(R) Core(TM) i5-2300 CPU @ 2.80Ghz - Quad Core
8.00 GB of RAM
Windows 7 - x64

I think it seems to run fine, it just doesn't display on my monitor, help please?

Hi

Could you list the rest of your system specifications first of all?

Sounds like my problem:

Try hitting F8 on startup and forcing 640x480. Does it work then? And if you then try and increase the res does it go no signal again?
