After downloading windows 8 updates on Sept 4, I started experiencing problems with computer black screening then shutting down. Occasionally I would get kernel mode driver unresponsive recovery complete without shutdown. After considerable troubleshooting, I found this driver 355.82 to be defective. My machine is now running on a driver about a year old and doing fine. I went to Nvidia website, it appears I am not the only one having problems although the other people are mostly gamers which I am not. I sent a bug report to Nvidia. My graphics card is a gt610 nothing fancy.
