This problem started for me a few days ago out of the blue. I hadn't recently installed any new programs or drivers. It began with just the screen freezing for a second and then returning to normal with the error message "Display driver nvlddmkm stopped responding and has successfully recovered." I was running an EVGA NVIDIA 8800GTS 640MB card at the time. Nothing on the computer is overclocked nor has it been. Then the next day the error started to happen more frequently so I upgraded the drivers to the most recent release 191.07 WHQL. After this I started to see a lot of screen artifacts and began to run some diagnostic tools like FurMark, each time I tried to run this it would eventually freeze up the OS, resulting in either a BSOD with nvlddmkm.sys (0x00000116) to blame or just freeze up the screen and never come back until a system reboot. All of the temperatures were always within operating ranges. I tried cleaning out the drivers and installing various releases, as well as pretty much every posted solution I could find, but nothing helped. Attached are some of the pictures of the artifacts I was seeing. I decided to contact EVGA who told me to RMA the card as it was under warranty. Since there were graphic problems in the BIOS they thought it had to be the card malfunctioning and not the drivers, etc.
I thought all would be well and good from here, So i popped in the only spare graphics card I have which is a BFG NVIDIA 6200OC PCI. Unfortunately the problem continued to some degree. I no longer have the graphic artifacts, but I am still getting the "Display driver nvlddmkm stopped responding and has successfully recovered." error whenever I try to do anything even minimally graphics intensive, for example looking though the pictures I posted at a fast pace, or even run the Windows Vista performance rating diagnostic. I decided to go ahead and do a fresh install of Vista, and even with that I am still getting the error message. Note that the OS was current with all updates in both cases.
I was hoping it was simply a defective graphics card, but even with a new card and a clean install of the OS, I am still getting the error message. All of the images are from when the 8800GTS was installed. I have done all the basic stuff like checking the HDD, RAM, virus scan, etc. Does anyone have any thoughts as to what could be causing this problem? Please let me know if any other information might be helpful.
