So, I have an AMD Radeon 6950 in my gaming rig. It's a pretty nice card and it's been serving me really well. Lately, however, it intermittently just doesn't work. I'll boot up my PC and have no video out, so I'll plug one of my monitors into the DVI on my mobo and, voila, I have picture on one screen and an error saying Catalyst does not support my current card (the mobo video driver). If I shut down my computer and start it up again, I'll sometimes get my video card.
If my video card shows up, it will work without flaw as long as my computer is still on, but if I shut it down, then who knows whether or not it will work when I boot again. It's a crap shoot.
Any ideas as to what the issue would be?
