I recently purchased a n ATI 4670 as a small upgrade to my on board chip.
I'm using windows 7 x64 and every now and then i'll have random graphic drivers crash while playing games.....doesn't matter which whether it's minecraft or Assassins creed: Brotherhood
I've tried fixing it myself by reinstalled windows 7 and trying both older drivers and the newest and no matter what i do the drivers still crash.....there's nothing wrong with the card because it worked flawlessy on windows xp and so did the drivers.
Which leads me to believe it's an OS issue...however i can't stick with xp as a gamer since some games are unsupported for xp such as just cause 2.
Any help will be appreciated lemme know if you have any questions.
