When:
This occurs when playing any GPU intensive game like Dying Light, Shadow Tactics Battle of the Shogun in Linux Mint 18.1 Cinnamon. It also occurs in Windows 7 SP1 while playing beam.ng drive.
It will occur within a few minutes of playing.

What happens:
The game will be playing fine. Suddenly, the screen will go blank, the monitor will display “No Connection” and turn off.
Logging into the computer by ssh shows Xorg running at 100%.

In Windows 7 SP1, it will report “The GPU has stopped responding and [Game] has reported a fatal flaw”, however the screen will recover.

My worry is, is my graphics card failing? It is less then 6 months old.

might be one or more of: power supply, mainboard, dirty/failing pcie slot, graphics card.
Good luck finding the cause.
