I can think of three things off the bat.

1. Do you need to test your video card to ensure that it is still working? ( Is there video of Bios when ou start the computer?)

2. Do you need to know what kind of video card you have or the specs of it? ( Start> Run> ' dxdiag ' > go to the display tab)

3. Do you need to see if the card is phisically damaged or dirty? (open case find card and inspect)

4. Do you need to know what other cards are compatible with your system for upgrading? (Find mobo specs and google)

Please reply.
