Nvidia driver issue with vista I think

A couple days ago my driver started to fail but then recovered each time.  My screen would go black and then go back to normal in a few seconds.  Last night after my computer went to sleep mode this morning I can't even get into window without hooking up an external monitor and even then only to Safe mode.  The blue screen of death tells me nvlddmkm.sys Address 8B880E060 base at 8B808000. Datestamp 47317db2
I think it's a driver issue but I've tried updating it in safe mode and no luck so I tried rolling it back no luck.  Please help if you can, I need the computer for my wedding coming up next week, it's got all the music on it!  I managed to back up all my data files last night (had a bad feeling) but I'm not sure how to restore the comp (or if that would work) without losing all my programs.

    Where do I find the nvidia directory?  But your solution seems to be on track another guys suggested I try deleting that file and I did and it got me into windows but with really messed up graphics and no way to change resolution.  I've readded the file to the system32 directory but can't find the nvidia directory

  • AKleiman Oct 30, 2008

    I've found like 8 files all called nvlddmkm.sy_ and chose the most recent one that says vista32 in the folder column and tried the DOS expand.exe thing by typing:

    EXPAND.EXE nvldmkm.sy_nvlddmkm.sys
    but then it says:
    No destination specified for : nvlddmkm.sy_nvlddmkm.sys
    I'm not to sure where to go from here.  Please advise.  Thanks again.

  • AKleiman Oct 30, 2008

    Ok I managaed to expand the file but same result.  Do I delete any of the old files in system 32 that have the same name?  Also which of the nvlddmkm.sy_ files should I be uncompressing.  There are 8 of them in different folders:
    WinVista 32 (C:\SwSetup\SP34602)
    WinVista 64 (C:\SwSetup\SP34682)WinVista 32 (C:\SwSetup\SP35880)WinVista 64 (C:\SwSetup\SP35880)WinVista 32 (C:\SwSetup\SP38280)WinVista 64 (C:\SwSetup\SP38280)WinVista 32 (C:\SwSetup\Video)WinVista 64 (C:\SwSetup\Video)

    I deleted the nvividia and all nvlddmkm.sys files from windows\system32 and windows\system32\drivers.  Restarted, got into windows with messed up graphics, it automatically re-installed the driver, I restarted, got blue screen of death.  Now can only get to windows safe mode and the nvlddmkm.sys file is in windows\system32\drivers but is file version created 11/7/2007.  This is different from 2/2007 ver  Ideas?

I don't know much about computers and have been struggling for weeks to try and fix this issue on my Dell XPS 1330 (I uninstalled the NVIDIA drivers and allowed them to automatically re-install several times, which worked in the short term but the issue of frozen screen kept coming back). It seems that the solution several people have suggested is to update your c:Windows\System32\Drivers\nvlddmkm.sys file (I found a very old one there), but I couldn't actually find the NVIDIA directory on my computer (oops). Instead, I went to my Dell Support Center, clicked on "Drivers and Downloads" and found a "recommended" download (nVidia driver, under "video", near the bottom). This seems to have updated my driver software and has put a newer version of the nvlddmkm.sys file in c:Windows\System32\Drivers for me. I've only just done this so not sure if it has completely fixed my problem, but it was very easy for a non-computer person, so I thought I'd share it...
Thanks, Catherine

You are right insaying that is video porblem. here is the fix.

This is what appears to happen.during the installation of the most current drivers 100.65 Vista, an OLD file nvlddmkm.sys is copied into windows/system32/drivers and not the current one
in the install. As a result the new drivers are attempting to access a file
dated 11/2006 instead of 2/2007 ver which is in the newest WHQL
driver ver 100.65 vista 32.

Fix: Go to windows/system32/drivers and rename nvlddmkm.sys to
nvlddmkm.sys.old. Go to the nvidia directory and find the file nvlddmkm.sy_
and copy it to windows/system32. Using the cmd window (DOS box) type
EXPAND.EXE nvlddmkm.sy_ nvlddmkm.sys. When the expansion is complete, copy
the new nvlddmkm.sys to windows/system32/drivers and restart the computer.

Your computer should now work properly.

You will notice that any uninstall and reinstall of nvidia drivers will not
remove the old nvlddmkm.sys file and will not overwrite it with the newer
version. You have to do it manually. I do not know why this happens but who
cares as long it is fixed.

Good luck...

    you have to specify the full path and the file name. no wild card.

    Windows XP and Vista is not a full version of DOS.

    expand.exe nvldmkm.sy_ c:\windows\system32\nvlddmkm.sys

    you did it the wrong way. you need to keep the Nvidia driver. and the nvlddmkm.sys, not the one from Windows.

    I hope yu still have the deleted file int he recycle bin. if not, then you have to get a working machine and download the files for the video. uncompress it and put the file back where it should be.

    like I say before the file is i Nvidia folder not the windows folder.

NVIDIA HPF1905 error message when i start windows

I think that your video card drivers need to update.If you have an internet connection go the site of your Laptop manufacture. Once there enter the model number of the laptop then request driver (usually found in the web site's "Support Section"). There you should be able to find all the drivers for your model laptop. so update them . hopefully no error message will appear.

It certainly does sound like a driver. I would just go on a driver update quest myself. Head over to nvidia and get the lastest Unified platform (nforce) driver at if you are using a nvidia sound card.

Try restarting the computer on safe mode with networking ( You can goto safe mode with networking by - restart your computer and start pressing the F8 button repeatedly till you get the new boot options menu) and then restore the computer to an earlier date to which the computer was working fine.

I have had the similar kind of issue and was not aware what to do. While searching the web, I got the info about TheBestPcDoctor and I contacted their support. My issue is fixed and the computer is running fine now. If you need you may also contact them @ or via 877-407-9229

Most probably the drivers downloaded from Nvidia is not the correct version or an older version for your video card. That is probably windows revert the best options drivers for your video card. You can check the version or the date windows automatically installed from the device manager. You also can also use "Microsoft Updates" to update your drivers.

To remove the video drivers, go to "safemode" and from the "device manager" uninstalled the video drivers.Be sure to download the correct version for you video card and run the installer from Nvidia.

Do update your DirectX too.

Hope it helps.
