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.

Below are some screenshots of what now happens to the monitor when it freezes. With this card (6200OC) I can't even get more than a few seconds before the driver crashes and the screen goes all scrambled.





This is from running FurMark or something similarly graphics intensive, here the computer completely freezes and has to be rebooted manually. If I even dare run a game it just crashes the driver and recovers with the game still running every 15 seconds. If I am using the windows performance diagnostic to rate the computer then it will show this kind of screen for a few seconds and then recover back to the desktop showing the error message "Display driver nvlddmkm stopped responding and has successfully recovered."

I have run some further diagnostic tests on my hardware and all still come up negative.

Update:

I decided to go ahead and try installing Windows XP on another HD to try and see if I would get any errors there. I installed XP and got all the Microsoft updates and latest drives and then ran FurMark. It ran without any problems at 640x480, 1680x1050, etc and even with 16x AA on. In my Vista installation the computer will freeze up after about 20 seconds at 640x480 without AA. I did notice one type of graphical problem in the Windows XP installation however, the images are attached below, these were simply screen shots taken from within Windows.

Does anyone have any further thoughts as to why I am having trouble in Windows Vista but not XP? I am pretty sure I have tried all the conventional fixes for the nvlddmkm.sys error. The motherboard is still under warranty and it has been suggested that this might be the root of the problem, but since I was not able to replicate the problem in XP, but getting artifacts or BSODs I am weary when it comes to RMA'ing the motherboard without any hard proof that it is the cause.

If your still getting this artifacts even after installing a fresh copy of OS (Vista and XP) and a spare video card. It looks that the problem could be with the video card slot of your motherboard.

So the problem has been fixed...for now. I decided to go ahead an see if the 6200OC could be faulty as well so I picked up an NVIDIA GeForce 210 512MB while I await my RMA replacement for the 8800GTS (a GT 250 512MB). Indeed my luck is just horrible, the 8800GTS died and then the 6200OC just happened to have been a bad card from the start, now all is well with the 210.
