Ddkmd.sys is a system file used by the Windows OS to communicate the information between hardware and software to carry out any specified function.

However, at times the ddkmd.sys can cause BSOD (blue screen of death) error. The error can occur due to several reasons and one of the common reasons being driver corruption and hardware incompatibility.

The problem usually occurs when you connect a new hardware component to your PC like a graphics card, a USB device or a second monitor, etc.

Unlike other system files where in case of a driver or hardware failure the hardware stops working or responding, the ddkmd.sys error usually leads to a system crash.

BSOD errors are nothing new to the Windows OS. However, being able to resolve the error at the earliest is important because the problem keeps crashing the PC every few hours.

Ddkmd.sys error displays different error messages which can be used to determine the cause of the BSOD. Here are the most common ddkmd.sys error messages that you may see on Windows.


In this article, we take a look at the best solutions to fix the ddkmd.sys error to help you resolve the blue screen of death problem on Windows computer.

2. Uninstall recently installed programs

  1. Go to the Windows search bar and type Control Panel..
  2. Select Programs and Features.
  3. Click on the Installed-On tab to make sure the programs are listed in the recently installed order.
  4. Start by uninstalling one program at a time. Remove multiple if all of them are added at the same time.
  5. You probably also need to restart the PC to check if uninstalling the program did the trick.

Note: It is very rare that ddkmd.sys error may occur out of the blue because an old driver got corrupted. Most of the time, the newly installed programs are the culprit.

So, if you have installed any new application or software in the past few days or hours and experiencing BSOD after that, it is a good idea to uninstall the software.

3. Disconnect the recently installed hardware

If you have installed a new USB hardware, graphics processor or even a second monitor to your PC, try to disconnect the hardware temporarily to see if the error is caused by faulty hardware.

The computer can malfunction if the hardware itself is faulty or the driver is corrupt.

If the ddkmd.sys error is resolved after disconnecting the hardware; you can diagnose the issue by updating the driver with the latest version or a previous version.

4. Update drivers

If you know what part of the hardware is causing the problem, you can try to update the driver to the latest available version.

If the ddkmd.sys error shows up while using a web browser like Chrome or Edge or while watching videos from YouTube or MediaPlayer; the faulty driver most probably is your display or video card driver.

The best solution to have all your drivers up to date automatically is to use a dedicated tool. 

Expert Tip: Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken. We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.

DuetDisplay is a software application for macOS and Windows PC that allows the users to use their iPad as the secondary display.

If you are using a secondary monitor with your computer, uninstalling any monitor software like the DuetDisplay and DisplayLink can fix the issue. You can uninstall the software from Control Panel.

Make sure you also delete any remaining drivers from the Temporary folder, Program Files, and Windows registry. Follow this article on how to clear leftover files after uninstalling software on Windows 10.

6. Disable / Uninstall antivirus

If you have an antivirus program installed on your PC, it may be a good idea to disable it temporarily and check if that has any effect on the ddkmd.sys error.

Antivirus software is known to create conflicts with system files and blocking legitimate connections due to security reasons.

However, if the security programs prevent a genuine program from functioning correctly, it can result in system errors. If you have recently installed an Antivirus program, disable it temporarily.

If the issue gets resolved, you may need to uninstall the antivirus and look for another program.  Preferably Malwarebytes is light on your PC and does not create problems with system functions.
