Sorry for the late reply-
I couldn't find any older versions on AMD's website really. Could be my fault.
What exactly happens is this: I start playing a game (for the most frequent example, Skyrim). After a while (used to be an hour or so, then dropped down to almost ten minutes), the game crashes. This crash happens like this: The screen goes dark, then my monitor says "no display" (or something like that). Then, I think, the screen turns to white. And then generally I force-quit the game using the task manager. Then, if I try to play the game again, or try to play another game, at the moment the game starts, I get a blue screen. Then the cycle starts again. If I reboot the computer before trying again to play a game, I don't get a blue screen, and instead, after a while, my game crashes. So, a reboot functions like a blue screen in that matter.
