I have an ATI HD 4670 graphics card. I have always had the "Enable hardware acceleration option" ticked in my flash players and all multimedia players. (Since I've been told it Takes load off of the CPU) But now, all of a sudden, I am getting a green screen with any program which uses it when displaying video content.
I haven't updated/deleted/modified any existing drivers or changed any settings regarding the graphics card. Why did this happen? More importantly, how can I resolve this? And does enabling hardware acceleration have a significant impact on performance, or should I just disable it everywhere?
