Encountering the “video_tdr_failure nvlddmkm sys” error on Windows 11 can be frustrating, especially as it causes your system to crash or display a blue screen. This error is typically linked to graphics card driver issues, hardware problems, or system conflicts. Fixing it restores system stability, prevents unexpected crashes, and ensures your graphics card functions smoothly. Before starting, ensure you back up important data and have administrator access to your Windows 11 device, as some steps require system-level changes.
What You’ll Need
- Administrator access to your Windows 11 PC
- Internet connection for driver updates
- Optional: A backup of your system or important files
Step-by-Step
- Identify the Cause: Determine if the error appears during gaming, video editing, or general use. This can help narrow down whether the issue is driver-related, hardware, or software conflicts.
- Boot into Safe Mode: Restart your PC and enter Safe Mode to prevent third-party software from interfering.
- Press Windows key + R, type “msconfig,” and hit Enter.
- Navigate to the “Boot” tab, check “Safe Boot,” and select “Minimal.”
- Click OK and restart your PC. It will boot into Safe Mode.
- Update or Reinstall Graphics Drivers: Outdated or corrupt drivers are common causes.
- Open Device Manager (press Windows key + X and select Device Manager).
- Expand “Display adapters.”
- Right-click your NVIDIA graphics card and select “Update driver.”
- Choose “Search automatically for updated driver software.” If Windows finds an update, install it.
- If no updates are found or the error persists, visit NVIDIA’s official website to download the latest driver for your GPU model.
- Run the installer, choosing a clean installation if available, to overwrite existing drivers.
- Adjust TDR Settings via Registry Editor: Increasing the TDR timeout can prevent the driver from resetting too quickly.
- Press Windows key + R, type “regedit,” and press Enter.
- Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers
- Right-click in the right pane, select New > DWORD (32-bit) Value, and name it “TdrDelay.”
- Double-click “TdrDelay” and set its value to 10 (decimal). This extends the timeout to 10 seconds.
- Close Registry Editor and restart your PC.
- Check Hardware and Temperatures: Overheating or failing hardware can trigger this error.
- Ensure your PC is well-ventilated.
- Use tools like HWMonitor or MSI Afterburner to check GPU temperatures. Ideally, keep GPU temps below 85°C.
- Inspect physical components for dust buildup or loose connections.
- If hardware issues are suspected, consider testing with another GPU or consulting a professional technician.
- Perform Windows Updates: Ensuring your system is up-to-date can fix compatibility issues.
- Go to Settings > Windows Update.
- Click “Check for updates” and install any available updates.
- Restart your PC after updates are installed.
- Run System File Checker and DISM: Repair corrupted system files.
- Open Command Prompt as administrator (search for “cmd,” right-click, select “Run as administrator”).
- Type sfc /scannow and press Enter. Wait for the process to complete.
- Next, run: DISM /Online /Cleanup-Image /RestoreHealth
- Restart your PC once the process completes.
- Disable Hardware Acceleration: Sometimes, hardware acceleration causes conflicts.
- Open the application where the error occurs (like Chrome or other software).
- Navigate to Settings > Advanced > System.
- Disable “Use hardware acceleration when available.”
- Restart the app and check if the error persists.
- Revert Overclocking Settings: If your GPU or system is overclocked, revert to default settings.
- Open your GPU overclocking utility (like MSI Afterburner).
- Restore default clock speeds and voltages.
- Apply changes and restart your PC.
- Reset Windows if Necessary: If none of the above work, consider resetting Windows as a last resort.
- Go to Settings > System > Recovery.
- Under “Reset this PC,” click “Get started” and choose to keep or remove your files.
- Follow prompts to complete the reset.
Common Mistakes
- Skipping safe mode — makes troubleshooting driver issues harder.
- Updating drivers from unofficial sources — can introduce malware or incompatible versions.
- Overlooking hardware issues like overheating or loose connections.
- Changing registry settings incorrectly — always back up before editing.
- Ignoring Windows updates — they often contain critical fixes.
Tips
- Always create a system restore point before making major changes.
- Use the latest NVIDIA drivers compatible with Windows 11 for optimal stability.
- Regularly clean your PC’s internals to prevent overheating.
- Monitor GPU temperatures during intensive tasks to catch overheating early.
- Consider using driver update tools like Display Driver Uninstaller (DDU) for clean removals.
- Keep your Windows OS up-to-date to ensure compatibility with hardware drivers.
Troubleshooting
If the error persists after following the above steps, consider the following:
- Perform a clean installation of your graphics driver: Use Display Driver Uninstaller (DDU) in Safe Mode to completely remove existing drivers, then install the latest official NVIDIA driver.
- Test with a different GPU: If possible, swap your graphics card to see if the issue is hardware-related.
- Check for system overheating: Ensure cooling fans are working correctly and thermal paste is applied properly.
- Run hardware diagnostics: Use built-in tools or third-party utilities to test RAM, GPU, and storage devices.
- Consult a professional: If hardware problems are suspected, seek expert help.
