No display on monitor when graphics card is plugged in?

I have a Gateway FX Gaming computer (Link: http://www.newegg.com/Product/Product.aspx?Item=N82E16883113075 ) and I try to plug in the video card given in the graphics description in link; "NVIDIA GeForce 9800 GT Over-Clocked w/ 512MB on board memory and DirectX 10" Which as far as I know the video card was made to fit the computer. When ever I try to plug the graphics card into my computer, I dont get any display on my monitor at all. Also, The power button-light flashes. Both fans (computer and video card) turn on and work, But after a minuite or so the computer turns off. My onboard normal graphics work normally but obviouly arent very good for gaming. If there is any way possible to fix this problem please reply I am very eager to resolve this issue.

Additional Details:
My computer hasnt worked with my graphics card before, therefor I decided to Restore my computer to factory settings and still didnt work and thats where I ended up now.
