I have/had a sapphire radeon 4870 x2 that recently just died out on me. With the card installed on my a780gxe/128m motherboard the video card has 3 solid red lights and I looked that up and what I found makes me think the card is dead. I get no display whatsoever and at least one time the computer just shut itself down after a few seconds of trying to boot up. Since my motherboard has onboard video I tried just removing the defunct card and plugging into that but I still get no display at all however the computer hasn't shut itself down yet. How would I get the onboard video to work so I can get into my computer and retrieve my school work? Thanks....
