In Vista, I'll get a BSOD from atikmdag.sys with 2 screens. In 7, I just get a complete freeze, no BSOD. I can only assume the same driver is at fault.
Just curious if any other ATI users with dual screens having system freeze issues?

I also suggest that you remove one of your video cards if possible and see if that solves your problem. I don't know if your single card will support dual screens, but CrossFire could be causing your problems.
