There are many posts about these error messages on the web, but no fixes other than switching to Linux, which worked for one gamer (I do not game on this laptop, but the problem would undoubtedly show up there as well). I downloaded a GPU stress/burn-in test program called FURMARK and it ran a complex moving video pattern flawlessly (99% load) It also stress tested the CPU with no problems. I added a TimeDelay qword line in the registry with a value of 8 per one website but it did not help. When the desktop returns, you get a message saying 'display driver has stopped responding and has successfully recovered.' You may also see occasionally 'Application has been blocked from accessing graphics hardware.' I have tried 5 Nvidia drivers including the latest one with no improvement. When playing any video, mp4 from a thumb drive, dvd movie, YouTube videos, etc., there are quickly problems like frame shaking, green checkerboard patterns, screen freezing (the soundtrack continues) and then you get a black screen for a few seconds. The video problem carried over into Win 10.
