OK I'm having some really random problem with an older video card of mine. I'm trying to build up my old P3-733 box as a second PC, and put my Geforce Quadro4 AGP card in it, but it comes up corrupted at post and stays that way... worthless. I've cleaned the contacts, tried everything I can, but it won't clean up. The wierd part is I can pop that same card into my other PC and it's perfectly fine. AND I can take my ATI X800 out of my primary PC and put it in the old box and THAT's fine too. So the card is fine in another computer, and the computer is fine with a different card. I've got NOTHING on the old PC so the power supply can't be too taxed, and it's a brand new PS as well. I'm so confused. (putting the X800 from my good computer in the old PC permanently is NOT an option either) Has anyone ever had anything like this?
