This issue has a workaround that 'fixes' the problem for most users..

The issue is Micro$ofts default TDR setting. Basically (simplified) Microsoft has determined that a program which hasn't responded in a given time should be restarted.

TDR stands for Timeout Detection and Recovery. This is a feature of the Windows operating system which detects response problems from a graphics card, and recovers to a functional desktop by resetting the card. If the operating system does not receive a response from a graphics card within a certain amount of time (default is 2 seconds), the operating system resets the graphics card.

Increasing the default TDR setting to 8 seconds gives the graphics card longer to complete its task. How to do that:

Open registry > regedit >  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers. In the box to the right you may or may not see  TdrDelay with a data value of (2). If you see that, double click and change the value from (2) to (8). If you don't see TdrDelay...right click on a open space and create a new Dword  and name it TdrDelay . Double click that and set a value of 8.

Note: The computer must be rebooted after making this change.
