Hey, I bought this PC around 2 weeks ago and I've ran a few times into this problem. The last time it happened was yesterday - I was playing WoW and was listening to some songs on youtube, I was constantly alt-tabbing and the last time I alt-tabbed into WoW I just saw the borders of WoW and knew it would crash like that. The computer doesn't go into a blue screen or something, the monitor just gets the color of the window I'm alt-tabbing into and doesn't load the picture. I can't alt+f4, or any similar commands, but I can still hear the audio from youtube. I wasn't low on battery, and this has happened with other games as well, however not with all games.
I ran a storage, memory and some other test using the built-in hardware diagnostic tool and they all passed.
