I've had this problem for a few weeks now. Each time i watch Flash video my video card overheats and computer crashes without blue screen. I have tried to take hardware acceleration off and on but it wont help. I have latest Flash installed and working. I also have beta drivers for my ATI 6970 card. Having beta or official drivers won't do difference, i still have crashes. It also does not have any difference what browser i'm using. (Internet explorer, Firefox, Opera or Chrome). Youtube videos also chrash this computer. I don't have any problems watching .AVI or Xvid videos, video card temperatures stay about 60 to 70 celcius. Only problem i have has something to do with Flash. I have Windows 7, Q9550, 4 GB of DDR2-800.
