If your Nvidia game play is being interrupted by a frozen screen, a black screen, or a blue screen of death with an Nvlddmkm.sys error message, try not to panic. This article will teach you how to fix this error message by creating a new file instance that can help your system get back on track.
Fix Nvidia Nvlddmkm.sys Error Message
Go to your NVIDIA folder (located in C:\NVIDIA), and look for the file named nvlddmkm.sy.
Next, copy the file at the root of C:. In most cases, this file name is C:\nvlddmkm.sy_.
Now, head to the system folder that houses your drivers (in many cases, this is C:\Windows\System32\drivers\).
Locate the nvlddmkm.sys file, and rename it as nvlddmkm.sys.old.
Now, open the command prompt by pressing the Windows key + R and typing cmd.
Type cd, followed by the Enter key. Then, type expand.exe nvlddmkm.sy_ nvlddmkm.sys, and press Enter again.
This command will allow you to unzip the nvlddmkm.sys file (which was previously saved at the root of C:) and create a new file instance.
Copy the new file to C:\WindowsSystem\32drivers, and then restart your PC to let the changes take effect.
