More about 6950 problems
  1. do you know how to flash bios's? If so you should save the current bios you have and then try and flash a regular 6950 bios onto the card and see if the problem is still there...buying a card with a custom bios on ebay is a little scary to me you never know what they have done to the bios (they could have set something wrong that will slowly kill the card over time)
  2. Dont know how to do it but i can dig around, what i found weird is that i can play all game max out an get excellent fps and dont get a problem, if something went wrong whit the bios flash should it crash on gamming?
  3. not necessarily....thats the problem when you start messing with custom BIOS's....things can get messed up causing funky issues with the card...was this always an issue or did it just recently start happening? Also have you tried updating your drivers to see if its a software issue first?
  4. It just happen sometimes, mustly when watching hd movies whit kmplayer+ and is really very ramdon, i can make it happen at my own will.

    i will do a clean install of everything, i have the lastest software, i will downgrade and c if that work
  5. ok yea you can get the latest drivers from amd website and try those to see if your issue is still there
