This is a well-known fix for this issue. During the installation of most graphic drivers in Windows 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 Stopped Responding Solution 1

Step 1: Download and install the latest graphic driver.

Step 2: Then go to C:\Windows\System32\Drivers and rename nvlddmkm.sys to nvlddmkm.sys.old.

Step 3: Go to nvidia directory (usually in C:\Nvidia or C:\drvvganVidia) and find the file nvlddmkm.sy_.

Step 4: Copy the file to your Desktop directory.

Step 5: Open cmd.exe by going to Start -> type cmd in the search box and hit enter.

Step 6: Change the directory to Desktop by typing chdir Desktop.

Step 7: Then, type EXPAND.EXE nvlddmkm.sy_ nvlddmkm.sys. Or,
expand -r nvlddmkm.sy_ nvlddmkm.sys

Step 8: When the expansion is complete, copy the new nvlddmkm.sys from your Desktop to C:\Windows\System32\Drivers

nvlddmkm Stopped Responding – Step 9: Restart your computer and the problem should be resolved.

nvlddmkm-sys-blue-screenYou will probably realise 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 have to do it manually. Nobody knows why but who cares as long it’s fixed.

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.

    it worked for me, i use win7
    those who still got problem after the process, try to realise 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’ve 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 cuz I keep getting BSOD -.-

  • Nanashi1337

    I posted 1h ago saying it might’ve 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 XD
    its stange, 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
