Question : Problem: No Video Display

I have a home built computer that lost its video display.  This has onboard video, not a card.

I have tried a new video card, but "nothing" will display.  I assumed if the onboard video went out, that I could install a video card in the PCIe slot and make it work.  No such luck.
(yes, I tried another monitor)

Any Suggestions???
Thanks!!!

Answer : Problem: No Video Display

I found the solution.  The BIOS did not recognize it at first, but after trying it several times, the BIOS came up and allowed me to change the video settings.

Thanks All!
