Fix: Nvlddmkm.sys Blue Screen BSOD Error in Windows 7/8/8.1

Filed in » Problems and SolutionsSubmitted by

Solution for nVidia display driver Nvlddmkm.sys issue
GPU: nVidia GeForce Graphic Cards
OS: Windows 8/7/8.1/Vista
Symptoms: Bluescreen or Stop Error 0x0000001E caused by nvlddmkm.sys, or often get a message: “display driver nvlddmkm.sys stopped responding and has successfully recovered“.
Solution: Replace the nvlddmkm.sys file with a newer version

This is a well-known fix for the issue. During the installation of most graphic drivers in Windows 8/7/8.1/Vista, an old version of nvlddmkm.sys is copied into C:\Windows\System32\Drivers and not the current one in the install. As a result the new drivers are attempting to access the file dated 2006 instead of 2010. We make no guarantee that this will work for you. But according to many users’ and our reports, this solution did fix it.

Nvlddmkm.sys Blue Screen BSOD Error in Windows 8/7/8.1

You will probably realize that any uninstallation and reinstallation of nvidia drivers will not remove the old nvlddmkm.sys file and will not overwrite it with the latest version. You will have to do it manually. Nobody knows why it wouldn’t get overwritten even with the run as administrator privileged.

BSOD Solution 2: Fix bad and corrupted registry

registry-easy-boxThe registry is the lifeblood of your system. It is a single place for keeping such information as what hardware is attached, what system options have been selected, how computer memory is set up, and what application programs are to be present when the operating system is started. Very Often when something goes wrong with the registry, it can cause major problems including the deadly BSOD problem. Unfortunately, Windows doesn’t have any built-in mechanism to fix corrupted registry errors. You’ll need to clean up your registry problems with a Registry Cleaner.

    This is all good. But I can’t delete the original file because I can’t run cmd as admin. Went on to google and done it all. If i can’t delete original file, the rest is not good.

  • Ediartofmagic

    I did as written but it didnt worked ! It did the 1st time but after a while a had again this error.I solved it again but after a couple of minutes it showed again blue screen. I solved it in safe mode and it worked only once but now it does the same thing.

    I’m using windows 7 x64 and Nvidia 8500 GT. When I start my PC the letters that show the system properties instead of being wiht have purple dots.

  • Holcickany91

    It worked for me and I use win7.
    Those who still got problem after the process, try to realize what cause the problem.
    After a week of bluescreen on win7 startup, I found out that if Populous (old strategy game) is installed, i get the bluescreen anyway. Too bad I had to delete it but at least my system is fixed.

  • Nanashi1337

    I think this guide might have solved my problem. If it did. I love you!

    I really hope it did, it’s been so frustrating, I haven’t been able to play any games at all because I keep getting BSOD.

  • Nanashi1337

    I posted an hour ago saying it might have helped me but, no, unfortunately it did not help me. The issue still persists.

  • Holcickany91

    Well, i still got BSOD but at least once in a month.
    Its strange, somehow it still finds its way to bug me.
    I tried to delete every f**kin piece of those games that caused the problem by accessing to the registry (regedit in run command) and using ctrl+f by for it.
    In my case I once installed Notrium and Populous 3 on win7 64 bit, and got BSOD with pointing on nvlddmkm.sys. Well I deleted all of the registry of them, and so far, no BSOD for me 2 weeks ago. I hope I solved my problem and gave you some helpful ideas for you problems.

  • Pumaheo

    Expand -r nvlddmkm.sy_ C: work for me in Win 7 64bit.

    I have this great problem with nvlddmkm.sys SDOD error

    I have acer z5770 and am trying to install windows 8

    Upon reaching installing devices portion. BSOD appears with the error.

    Question is how am I supposed to install windows 8 on this machine.

    By the way, it runs perfectly well with windows 7 x64 ultimate so I really don’t have
    the idea why it should not run windows 8.


  • pankaj

    I am getting “Nvidia drivers cannot install in safe mode”!

  • yoko

    Works for my GTS 250!
    Really appreciate this and you save my day.
    Thanks in advance my friend.

  • Orioli

    Enter ‘Control Panel’, find ‘Power Saving’ and select ‘High Performance’. This should disable window’s PCI power saving, preventing BSODs related to your NVIDIA card malfunctioning (due to not having enough power).
