I have a problem with mobility radeon 5870. It's all great untill I launch Fallout 3 or Drakensang(I haven't tried anything different). Then game hangs up/I see a grey screen/sometimes also appears vertical lines. It was all the same with asus drivers( I have Asus G73jh) and the newest ATI Catalys 10.10 for win7 64. I don't know card temperatures because they don't appear in Everest. Anyone knowing what should I do?
