Nvidia Drivers and Windows Vista

As of late, a seacrh on the web for the BSOD caused by the nvlddmkm.sys driver will yield many different “fixes” users have done to solve their problem. However, they did nothing for me. I have found another way that has not been mentioned. The video adapter I currently have is in the HP Slimline S3220N integrated nVidia GeForce 6150SE. Many sites I visited had suggested to navigate to the C:\Windows\Systen32|Drivers folder and remane the nvlddmkm.sys file to nvlddmkm.sys.old and the go to the nvidia driver folder and expand the nvlddmkm.sy_ in the the C:\Windows\Systen32|Drivers folder. Some claimed success but many still have had the same problem. Since I could not boot up under normal mode, I had to boot up in Safe Mode. I used Safe Mode with networking so I can access the internet. What I did was to visit the HP (or whatever your computer manufacture} website and downloaded the oldest display driver. The I went to the nVidia website and downloaded the newest driver. I then navigated to the device manager and uninstalled the video adapter. I installed the old video driver and restarted. I was able to boot into normal mode but once windows had finished installing the driver and restarted, the BSOD reappeared. I then rebooted into Safe Mode. This time, I navigated to the Device Manager and checked the drier version and also navigated to the C:\Windows\System32\Drivers folder to see if the nvlddmkm.sys were the same file number. Then I went to the nVidia downloaded file and started the update. Once the update was finished, I tried to start into normal mode. I still got the BSOD so I has to reboot into Safe Mode. I then went to the device manager and looked up the dipslay driver and then updated the driver with same driver. You should be able to reboot into normal mode. This had worked for me. Now if by chance it does not, then reboot into safe mode and navigate to the C:\Windows\System32\Drivers folder and rename the nvlddmkm.sys file to nvlddmkm.sys.old and reboot. This will only make the display a standard vga but it will work until nVidia is able to fix the problem.
