Ok then. The game video and audio both lock up, audio continues to play the same sounds as when it froze. Alt+F4 will NOT close the game. Alt+Tab will NOT minimize the game. Sometimes the Win-key will bring up my task bar, but i cannot click on anything or even see my mouse pointer. Ctrl+Alt+Del does NOT bring up the Task Manager, or i cannot see it. I can using keyboard commands switch users log off, shutdown, or restart. Usually to fix the problem fastest is to switch users, and relog into my account of my computer. After i do that I can Ctrl+Alt+Del to bring up the task manager, and can kill AH from there.
