I am getting a reproducible system crash. When it occurs, it is always getting into or getting out of a game, while the game is running. The three games that this has happened on are Worms Armageddon, America’s Army, and the Unreal Tournament 2004 demo. It always seems to occur when 1. I am minimizing the game, in the game, and trying to come back to Windows. 2. I am trying to get back into the game after I do #1 (while the game is still running). *I am not sure 1 and 2 happen 100% of the time, but very, very often. 3. When I am exiting the game and coming back to Windows. *3 does not happen every time. It always occurs during the transition, (when the screen is flipping to the game or to Windows) Example: I can do the following and it will crash every time. 1. Start America’s Army 2. At the main menu I will then press the Windows-icon button on the keyboard. This brings me back to Windows. 3. Then I click on the Americas Army tab in the taskbar. 4. The screen goes black, like its getting into the game, but then immediately it crashes and restarts. After it reboots, Windows gives me the critical error message and says that “A device driver may have caused this problem”. This happened before I updated the graphics driver and after I downloaded the latest driver. MY COMPUTER My computer is a brand new Hp pavilion a850e. Here are the specs.
