I have been using windows 7 64 bit for about 3 weeks now and have been having trouble with my Nvidia Geforce 9800 GTX+. Every so often when I'm using a more heavily graphic process the screen with go black for a second then reappear with a message about the NVIDIA DRIVER KERNEL HAS STOPPED WORKING AND HAS SUCCESSFULLY RECOVERED. I've been looking around and have been told to try a different driver. Tried with no avail. Used the 185.81, 186.08, the 186.18 and the 181.22 drivers with no change. Also, sometimes the card will not recover and blue screen. Any help?
