Before solving a computer problem, I always recommend scanning and correcting the underlying problems that affect the health and performance of your PC:

  • Step 1 : Download the PC repair and optimization program (WinThruster for Win7, XP, Vista – Microsoft Gold Certified).
  • Step 2 : Click the Start scan button to detect problems in the Windows registry that may cause problems with the PC.
  • Step 3 : Click the Restore All button to solve all problems.

Setting up automatic weekly (or daily) scanners will help you avoid system problems and get your PC up and running quickly and smoothly.

Wally’s answer: Most cases of errors on the blue screen in Nvlddmkm.sys seem to be related to problems with the graphics driver. So that’s what we’re gonna focus on.


The blue Nvlddmkm.sys screen error appears when you try to close Windows.


The Nvlddmkm.sys bluescreen error is usually caused by damaged device drivers, especially the graphics driver.


Here are some ways to correct the blue screen error in Nvlddmkm.sys.

Scroll backwards for the latest driver updates

Have you recently updated the drivers of your device? If that’s the case, it’s probably the change that caused the problem. You can cancel a defective driver update via the Device Manager.

Press Windows + X and click on Device Manager.

Right-click on the device whose driver you have updated and select Properties or double-click on it.

Now click on the Driver tab and click on the Roll-Back Driver button.

Graphics driver update

Since the error on the blue screen Nvlddmkm.sys usually occurs due to an error in the video driver, updating the video driver to the latest version may solve the problem.

You can do this by visiting the website of the manufacturer of the graphics card. Find a driver by searching the website. Be sure to download the version created for the correct version of Windows. After downloading, install it and restart your computer for the changes to take effect.

If you do not want to do this, or if you are new to installing drivers, you can also use DriverDoc to update the drivers automatically.

Graphics driver downgrade

If the graphical driver update does not work, you will need to downgrade the driver to an earlier version that worked properly.

To do this, you need to go to the website of the manufacturer of your graphics card. Here you need to find the video card of your computer by searching for the model and downloading the driver.

There must be an option somewhere to load an older version of the driver. If you can’t find this option, please contact customer service or ask me on Facebook.

Increase the GPU processing time using the Windowsregistry

The Windows timeout detection and repair function detects when a graphics card (and other devices) takes too long to respond.

If the answer is too late (more than 2 seconds), it may cause an error on the blue screen Nvlddmkm.sys. By dedicating more time to this function, this problem can be avoided. To do so, follow the steps below:

Pay attention: The Windows registry is an integral part of the function, so edit it carefully and always save the registry before making any changes. To do this, click File > Export… and save the registry settings in a safe place.

  1. Open the Run window with the Windows key combination Key+R
  2. Type Regedit and press Enter
  3. Copy and paste the address of the next registration subkey into the address bar of Regedit:
  4. From the Edit New menu and then from the drop-down menu, select the registry value according to your version of Windows (32-bit or 64-bit):

Select QWORD (64-bit).

  1. Enter TdrDelay as name and press Enter.
  2. Double click on TdrDelay, add 8 as the value and click OK.
  3. Close the Registry Editor and restart the computer for the changes to take effect.

Is your PC in good health?

I always advise my readers to regularly use a reliable registry cleaner and optimizer such as WinThruster or CCleaner. Many of the problems that arise can be attributed to a corrupt and inflated register.
