Did this just start happening recently?
Try a clean re-install of the nvidia graphics drivers. See
here or
here, for example.
If that doesn't help, you can use a program called
TDR Manipulator to change a Windows setting which controls if and how Windows restarts the video drivers. Telling Windows to stop the resets may eliminate the crashes with the game, though if there is an actual problem causing the resets it will not be fixed, and could potentially lead the computer freezing.
If you upgraded to Windows 10, you could try reverting back to Win 7/8, possibly installed to a different drive/partition. That helped one person with this error:
DXGI ERROR Crash - turned WIN 10 conflict.
