Bit of a long story but here I go.
I have 2 Radeon 6950 with the crossfire thing set up, it's been working well for over 2 years.
Over the last few weeks I've been having issues, mostly while watching videos (usually HD and/or full screen). The video will freeze, the audio will loop, then eventually the screen goes black and I get an error message saying "Display driver has stopped working and has recovered".
Sometimes it didn't recover and I have to turn the computer off.
What's now happening is it will freeze at the windows start up. Then after resetting I will get to windows in very very low resolution and in black and white.
So I 're-seated' the cards. I couldn't notice any obvious damage to it except the fans were very dusty so I cleaned them.
Boot it up and I still get the black and white.
I checked the device manager and it said one of the cards was having problems, I uninstalled both drivers from that menu (not quite sure if I should have done this) and for whatever reason it's now working.
However it now seems one of my cards is not being recognised. Only one display adapter is shown in the device manager and AMD catalyst only recognises one card too.
What's the best course of action to determine what's wrong with what card (still not quite sure which one it is).
