Hi, i unistalled drivers
and removed leftovers with driversweeper, didn't helped. I installed older hotfix drivers(11.1) which fixed aero, except that sometimes i still see dots instead of text in upper left corner. About the newest hotfix drivers(11.6), they don't work, after install I get atikdmag.sys bsod at startup every time(fixed with system recovery). But the main problem is with violet graphics. As I mentioned above, it happens on only some games, like assassins creed 2, assassins creed brotherhood, burnout paradise and nfs carbon if I put visual treatment on high. Other games, like Assassins creed 1, mass effect 2, Darksiders work fine. Please help me with this problem, I don't know what to do anymore.
