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 serious BSOD (blue screen of death) error in Windows PC leaving the user frustrated.

The Ddkmd.sys 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.

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.

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

What causes Ddkmd.sys errors?

As, I, mentioned earlier, Ddkmd.sys error isConfirm your System Restore point usually caused by faulty hardware that you recently connected to your computer or a corrupt driver failure or software issue.

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.

What type of Ddkmd.sys errors are there?

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 message that you may see on Windows.


How can I fix Ddkmd.sys BSOD errors?

The Ddkmd.sys error can occur due to several reasons; as a result, I have listed more than one solution to this problem. Based on what all the solutions you have tried already, scroll through the solutions to find the one that you haven’t tried yet.

Solution 1: Uninstall Recently Installed Programs

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.

  1. Go to Control Panel > Programs > Programs and Features.programs and features speed up Windows 10 PC
  2. Click on the Installed-On tab to make sure the programs are listed in recently installed order.
  3. Start by uninstalling one program at a time. Remove multiple if all of them are added at the same time.
  4. You probably also need to restart the PC to check if uninstalling the program did the trick.

Bonus Tip: If you are unable to uninstall any driver or software from the control panel, use the trial version of Revo Uninstaller Pro and uninstall the driver or software.

Solution 2: 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 a faulty hardware.

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

Solution 3: Uninstall DuetDisplay / DisplayLink

DuetDisplay is a software application for macOS and Windows PC that allows the users to use their iPad as the secondary display. While the software has been developed to increase productivity, some users have reported it to be conflicting with the core functions resulting in Ddkmd.sys error.

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 > Programs > Programs and Features.

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.

Solution 4: 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; this security program is light on your PC and does not create problems  with system functions.

Solution 5: Update Drivers

Run a System Scan to discover potential errors

Run a PC Scan with Restoro Repair Tool to find errors causing security problems and slowdowns. After the scan is complete, the repair process will replace damaged files with fresh Windows files and components.

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

Even if you are running the latest version, simply uninstall it and install a fresh version from the official site or your computer manufacturer’s website.

Here is how to update/uninstall the driver. First, make sure you have the latest version of the device downloaded to your PC. You can know the version of the current driver installed by doing the following:

  1. Open Device Manager by typing Device Manager in the Cortana/Search bar. Alternatively, you can also open Device Manager from the Control Panel.
  2. From the Device Manager > right-click on the hardware you want to update and select Properties.
    Device Manager - Driver Properties
  3. Open the Driver tab and look under the Driver version to find the current driver version. You can know more about the driver such as driver name from the Details tab.

To Uninstall / Update the Device Driver, do the following:

  1. Open Device Manager.
  2. Click on View and select Show Hidden Devices.
  3. Scroll through the available device and expand the section by clicking on the > icon.
  4. Right-click on the device you want to update and click on Update driver. If the device already has the latest version installed, select Uninstall the device.
    Uninstall Device- Device Manager
  5. Now double-click on the downloaded driver and install it on your PC manually.

Restart your PC after the driver is successfully installed. If the issue persists, try to download an earlier version of the driver to see if the latest version of the driver is causing the problem.

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.

If you have a dedicated GPU, download the latest version of the driver from the official website. If not, download the Intel HD display driver depending on your processor.

Solution 6: Restore System to an Earlier Point

Windows PCs come with a System Restore feature by default. When enabled, it creates an automatic restore point before any major update or program installation.

Using the Restore Point, you can restore your PC to a point where it was working without any issues.

Here is how to perform a System Restore without deleting any files.

Note: While restoring your PC to an earlier point, the PC will uninstall all the software installed between that period.

  • In the Cortana/Search bar type Restore and select “Create a System Restore” option from the search result.
  • From the System Properties window, click on System Restore button. This will open a System Restore dialogue box.
    System Restore - System Properties
  • Click on Next button to proceed. Here you can see the most recently created Restore points with time and description.
    System Restore Point Select
  • Check “show more restore points” option to see all the system restore points available on your PC.
  • Select one of the restore points and click “Scan for affected programs”. Doing so will show you which all programs will be affected by this system restore.
  • Once decided, click on Next button.
    Confirm your System Restore point
  • Now you need to confirm your restore point. Click on Finish button when you are ready.

The restore process may take a few minutes to complete. Once done, the PC will restart automatically.

Solution 7: Run Windows System File Checker

Windows OS comes with a built-in command based system file check tool that can help you with repairing corrupted or missing system files using a cached copy located in the hard drive. Here is how to use the tool.

  1. In the Cortana/Search bar type cmd. Right-click on Command Prompt and select Run as Administrator. If prompted with a permission dialogue box, click Yes.
  2. In the Command Prompt window, type the following command and hit enter.
sfc /scannow

The System File Checker Tool will now look for any corrupted or missing files and fix them automatically.
