How To Fix Video_Dxgkrnl_Fatal_Error In Windows 10

The VIDEO_DXGKRNL_FATAL_ERROR is a blue screen stop code that points to problems with the DirectX graphics kernel subsystem on Windows 10. This usually means an issue with your graphics drivers or related hardware, and it can make your PC unstable or unusable. Tackling this error requires a methodical approach, focusing on both software and hardware that manage your computer’s display and graphics processing.

Understanding the VIDEO_DXGKRNL_FATAL_ERROR

This error is triggered when Windows detects a critical problem in the DirectX Graphics Kernel subsystem. Often, it’s due to incompatible, outdated, or corrupt graphics drivers, but it can also stem from hardware faults or software conflicts. The BSOD typically shows the stop code VIDEO_DXGKRNL_FATAL_ERROR and forces your PC to restart, sometimes on every boot.

DirectX is a suite of APIs used for handling tasks related to multimedia, especially game programming and video. The dxgkrnl.sys file is crucial for graphics operations. If it malfunctions, you’ll see this stop code. Understanding the underlying cause is key to finding the right fix.

Update or Reinstall Your Graphics Drivers

Faulty graphics drivers are the most common culprit behind this error. To update your drivers, press Win + X and choose Device Manager. Expand Display adapters, right-click your GPU, and select Update driver. Choose Search automatically to let Windows find the latest version. If the automatic update does not help, visit your GPU manufacturer’s website (NVIDIA, AMD, or Intel) to download and install the newest driver manually.

If updating doesn’t work, try a clean reinstall. In Device Manager, right-click your GPU and choose Uninstall device. Check Delete the driver software for this device if the option appears. Reboot your computer. Windows will attempt to reinstall a basic driver. Then, use the official driver package from the manufacturer to reinstall the latest version.

Run Windows Update and Check for Optional Updates

Microsoft often releases patches and driver updates via Windows Update. Go to Settings > Update & Security > Windows Update and click Check for updates. Install all available updates, including optional ones that may include graphics or chipset drivers.

For some GPUs, updated drivers are provided as optional or recommended updates. Click View optional updates under the Windows Update page to check. Install any graphics or hardware-related updates. Restart your computer after the updates complete to see if the error persists.

Check for Overheating and Hardware Issues

VIDEO_DXGKRNL_FATAL_ERROR can result from physical problems with your GPU, RAM, or motherboard, especially overheating or failing hardware. If your PC is dusty or poorly ventilated, overheating may be causing the system to crash under load. Power down, open the case, and carefully clean dust from fans and heatsinks using compressed air. Ensure all cables and cards are firmly seated.

If you have a dedicated GPU, reseat it by removing and reinserting it into the PCIe slot. Look for visible signs of damage or burnt components. If possible, test your graphics card in another machine, or swap in a working card to see if the issue persists. Running a memory diagnostic can also help rule out bad RAM: open the Start menu, type Windows Memory Diagnostic, and follow the prompts.

Run System File Checker and DISM Commands

Corrupted system files could be interfering with graphics components. Open Command Prompt as an administrator and run the following commands in order:

• sfc /scannow - Scans and repairs corrupted system files.
• DISM /Online /Cleanup-Image /RestoreHealth - Repairs Windows system image and component store.

Let each command finish before running the next. If any errors are found and repaired, restart your computer and check if the blue screen still appears.

Rollback Recent Windows or Driver Updates

Sometimes, a new Windows update or driver version introduces compatibility issues that trigger the VIDEO_DXGKRNL_FATAL_ERROR. If the error started after a recent update, try rolling back to a previous version. In Device Manager, right-click your graphics adapter, choose Properties, go to the Driver tab, and click Roll Back Driver if the option is available.

To uninstall recent Windows updates, go to Settings > Update & Security > Windows Update > View update history > Uninstall updates. Remove any updates installed around the time the error began. Reboot and test for stability.

Disable Fast Startup and Hardware Acceleration

Fast Startup can cause driver initialization problems on some systems. To disable it, open Control Panel > Power Options > Choose what the power buttons do. Click Change settings that are currently unavailable, then uncheck Turn on fast startup. Save changes and reboot.

Some users also find disabling hardware acceleration in browsers or other apps helps. In Chrome, for example, go to Settings > System and disable Use hardware acceleration when available. In other programs, look for similar graphics settings. This reduces GPU load and can stabilize the system if the error is related to certain workloads.

Perform a System Restore or Reset

If none of the above steps resolve the error, use System Restore to revert your PC to an earlier state when it was working fine. Search for System Restore in the Start menu, follow the prompts, and select a restore point from before the issue appeared.

If System Restore is unavailable or doesn’t fix the problem, as a last resort, perform a reset or reinstall of Windows. Go to Settings > Update & Security > Recovery, then choose Reset this PC. You can keep your files or remove everything depending on your preference. This will reinstall Windows and often fixes persistent BSODs caused by severe software corruption.
