2] Update or Reinstall DirectX¶

Issues with dxgkrnl.sys might stem from corrupted or outdated DirectX components. While Windows Update typically handles DirectX updates, ensuring your system has the latest versions and that the existing files are intact can help. Manually “reinstalling” DirectX isn’t a straightforward process for modern Windows versions as it’s integrated into the system. However, you can ensure its integrity by running system file checks or allowing Windows Update to manage it.

The best approach is usually to ensure Windows is fully updated, as this includes updates to DirectX components. You can check for updates via Settings > Windows Update. If you suspect corruption, the system file checker and DISM commands mentioned below are effective tools for repairing DirectX files indirectly by verifying and restoring core Windows components. Ensuring your graphics drivers are current (as discussed in step 4) is also crucial, as drivers provide the interface between DirectX and your hardware.

3] Use DISM and SFC Commands¶

Corrupted system files are a common cause of various BSODs, including those related to dxgkrnl.sys. Windows includes powerful command-line tools, the System File Checker (SFC) and Deployment Image Servicing and Management (DISM), to verify and repair system file integrity. DISM is often used first to ensure the Windows image itself, which SFC relies upon, is healthy.

To use these tools, you need to open Command Prompt with administrator privileges. Press Windows Key + X and select Command Prompt (Admin) or Windows Terminal (Admin), then choose Command Prompt. Once the window opens, execute the following DISM commands sequentially. Each command performs a different check or repair operation on the Windows component store and system image.

First, check the health of the image:

Dism /Online /Cleanup-Image /CheckHealth

Then, scan the image for corruption:

Dism /Online /Cleanup-Image /ScanHealth

Finally, attempt to restore the image using files from Windows Update:

Dism /Online /Cleanup-Image /RestoreHealth

Allow each command to complete fully before running the next one. This process can take some time. After running DISM, it’s recommended to run the System File Checker command to repair any corrupted or missing system files that DISM might not have fixed directly:

sfc /scannow

The sfc /scannow command will scan all protected system files and replace corrupted ones with cached copies. This process also takes time and should be allowed to finish without interruption. After running both DISM and SFC, restart your computer and see if the dxgkrnl.sys error persists.

4] Update, Rollback, or Reinstall Drivers¶

Driver issues, particularly with the graphics driver, are a primary suspect when facing dxgkrnl.sys errors.
