8 Easy Ways to Fix the nvlddmkm.sys Error in Windows 10

Of all the Blue Screen of Death (BSoD) issues that come up on your Windows computer, some of them are caused by the hardware components of your system. This further branches into many other types of BSoDs, one of which is caused by some mistakes related to your graphics card. This is the Nvidia nvlddmkm.sys Video TDR failure error and this is the article that will help you fix it on your PC.

What is nvlddmkm.sys?

The Nvidia Windows Longhorn Display Driver Model Kernel Mode (nvlddmkm.sys) driver is a Windows Display driver that is responsible for the communication between your Nvidia graphics card and the Windows Operating System (OS).

What does Video TDR failure mean?

TDR stands for Time Detection and Recovery and is a Windows feature that resets your computer’s functioning Nvidia graphics driver if it does not respond to the Operating System within a short deadline. The computer is set to a normal state if your Nvidia GeForce GPU card isn’t responsive for a long time, without restarting it.

If the Time Detection and Recovery tool does not troubleshoot your computer when it notices no responses from the GPU that is connected to the system, it means that you are facing the Video TDR failure. When your system is put in a very uncomfortable situation like this, it resorts to crashing and displaying a Blue Screen error.

This issue usually happens when the user is playing games, rendering 3D structures, watching or editing videos, or any other process that uses a large volume of the Graphics memory for a prolonged time period.

Factors that cause the nvlddmkm.sys Video TDR failure Blue Screen error (nvlddmkm.sys)

1. Incompatibility of the Graphics Card’s drivers

There could be an incompatible graphics driver software version present on your computer. You may be able to find a driver that works perfectly on your computer and supports the processes that need to use this hardware. 

2. Invalid voltages and/or memory timing

If the timing information or the core voltage of your graphics card is not accurate, you could see the Video TDR failure of your Nvidia graphics card.

3. Overheating issues

It is not safe for any hardware component to be very hot. Extensive heat can cause damage to this and reduce performance. Sufficient cooling or lowering the settings configuration can cool your PC down.

4. Memory issues

There can be some issues with your RAM, which can cause several problems including Video TDR failure.

5. Graphics Card restrictions

It is possible that some features are restricted to be used with the graphics card. Breaking this rule can cause many video outputs related problems. 

6. Too many running processes

If processes are running more than your CPU can handle, you will have a very slow computer. If you try launching programs that use the GPU, it could be very choppy.

Fix Nvlddmkm.sys System Error on Windows 10

Update your Graphics Card Drivers

You will not get the best performance out of your graphics cards if you have an outdated graphics card driver. This can also cause some problems for you. It is important for you to have the latest drivers on your computer.

There are applications like the Nvidia GeForce Experience and Radeon Adrenalin, which notify you when there are pending updates and allow users to automatically download updates with a press of a button. 

If you would like to update your drivers the classic, manual way, here is the procedure:

Before we get started, It is important that you know the Nvidia GPU model that you have on your PC. You can find your model in the video card interface or the display adapters section in the Device Manager. 

  1. Press Windows key + R key to bring up the Run tool. 
  2. Type in the run command “dxdiag” and hit enter on your keyboard. This is the command for opening the DirectX Diagnostic Tool window. 
  3. Open the Render tab. It will have details of your dedicated graphics card. Your integrated GPU information can be found in the Display tab.

  1. Make note of the model and close the window.
  2. Next, search for System Information in the taskbar search box and open the best match.
  3. In the System tab, Next to the System type heading, you should be able to see x64 or x86 based PC. If you see x64, it means that your OS is a 64-bit type. If it is x86, you have a 32 bit OS running on your system.
