dxgkrnl.sys VIDEO_TDR_FAILURE: Simple Step-by-Step Fix

Your computer just froze. A blue screen appeared. And somewhere in that wall of error text, you saw “dxgkrnl.sys.” Now you’re wondering what broke and how to fix it.

This file is a critical part of Windows graphics management. When it fails, your system crashes. The good news? Most dxgkrnl.sys errors are fixable once you understand what’s causing them.

Let me walk you through everything you need to know.

What Is dxgkrnl.sys?

The dxgkrnl.sys file is the DirectX Graphics Kernel subsystem. It’s a system driver that manages communication between Windows and your graphics hardware.

Think of it as a translator. Your operating system speaks one language. Your GPU speaks another. This file bridges that gap.

Where you’ll find it: C:\Windows\System32\drivers\dxgkrnl.sys

What it does:

• Manages GPU memory allocation
• Handles display outputs
• Coordinates graphics rendering tasks
• Controls power management for graphics hardware
• Enables multiple monitor support

Every time you open a game, watch a video, or even move a window across your screen, dxgkrnl.sys is working in the background.

Why dxgkrnl.sys Causes Blue Screen Errors

When this file crashes, Windows can’t safely manage your graphics hardware. The system triggers a BSOD (Blue Screen of Death) to prevent data corruption or hardware damage.

Common error codes you might see:

Error Code	What It Means
VIDEO_TDR_FAILURE	The graphics driver stopped responding and recovered, but dxgkrnl.sys couldn’t handle the timeout
SYSTEM_SERVICE_EXCEPTION	The kernel encountered an illegal instruction or accessed invalid memory
PAGE_FAULT_IN_NONPAGED_AREA	The system tried to access memory that doesn’t exist
DRIVER_IRQL_NOT_LESS_OR_EQUAL	A driver accessed memory at the wrong priority level
ATTEMPTED_WRITE_TO_READONLY_MEMORY	A driver tried to modify protected system memory

These errors share common root causes. Let’s look at what actually triggers them.

Main Causes of dxgkrnl.sys Errors

Outdated or Corrupted Graphics Drivers

This is the number one culprit. Graphics drivers get updated frequently. Old drivers contain bugs that newer Windows updates don’t account for. Sometimes driver files become corrupted during installation or from disk errors.

Hardware Issues

Your GPU might be overheating, failing, or drawing unstable power. RAM problems can also trigger dxgkrnl.sys crashes since the file manages graphics memory.

Software Conflicts

Certain programs modify how graphics rendering works. Screen recorders, overlays, RGB control software, and even antivirus programs can interfere with normal GPU operations.

Windows Update Problems

Major Windows updates sometimes break compatibility with existing drivers. The anniversary updates, feature updates, and even monthly patches can introduce conflicts.

Overclocking Instability

If you’ve overclocked your GPU or CPU, unstable settings will cause random crashes. The graphics kernel is particularly sensitive to timing issues.

Malware or System File Corruption

Malicious software can modify system files. Even without malware, regular use can corrupt files through improper shutdowns or disk errors.

How to Fix dxgkrnl.sys Errors

Start with the simplest solutions first. These fixes work for most people.

Update Your Graphics Drivers

This solves the majority of cases.

For NVIDIA cards:

1. Open GeForce Experience or visit NVIDIA’s driver download page
2. Enter your GPU model
3. Download the latest Game Ready Driver
4. Run the installer and choose “Custom installation”
5. Check “Perform a clean installation”
6. Restart your computer after installation

For AMD cards:

1. Download AMD Software Adrenalin Edition
2. Run the installer
3. Choose “Factory Reset” if offered
4. Complete the installation
5. Restart your system

For Intel integrated graphics:

1. Visit Intel’s download center
2. Use the automatic detection tool
3. Install the recommended driver
4. Restart

If you’re still getting crashes after updating, the driver itself might be the problem. Try rolling back to an older, stable version.

Roll Back Your Graphics Driver

Sometimes the newest driver introduces bugs.

1. Press Windows key + X
2. Select Device Manager
3. Expand “Display adapters”
4. Right click your graphics card
5. Choose Properties
6. Click the Driver tab
7. Select “Roll Back Driver” if available
8. Choose a reason and confirm

If rollback isn’t available, manually install an older driver version from the manufacturer’s website.

Run Windows Memory Diagnostic

RAM problems often masquerade as driver issues.

1. Press Windows key + R
2. Type “mdsched.exe”
3. Press Enter
4. Choose “Restart now and check for problems”
5. Let the test complete (takes 10-20 minutes)
6. Check results after restart

If errors appear, you have faulty RAM. Test each stick individually to identify the bad module.

Check for Overheating

Thermal throttling and crashes go hand in hand.

Monitor your temperatures:

1. Download HWMonitor or MSI Afterburner
2. Run a graphics-intensive task
3. Watch your GPU temperature

Safe temperature ranges:

• Idle: 30-45°C
• Load: 65-85°C
• Danger zone: Above 90°C

If you’re hitting 90°C or higher:

• Clean dust from fans and heatsinks
• Improve case airflow
• Replace thermal paste on older GPUs
• Consider undervolting if the problem persists

Disable Hardware Acceleration in Applications

Some programs stress the graphics kernel unnecessarily.

In web browsers:

Chrome/Edge:

1. Settings > System
2. Turn off “Use hardware acceleration when available”
3. Restart browser

Firefox:

1. Settings > General > Performance
2. Uncheck “Use recommended performance settings”
3. Uncheck “Use hardware acceleration when available”

In Discord:

1. User Settings > Advanced
2. Disable “Hardware Acceleration”

Test if crashes stop. If they do, the problem is software conflict, not hardware failure.

Run System File Checker

Corrupted Windows files cause unpredictable crashes.

1. Open Command Prompt as administrator
2. Type: sfc /scannow
3. Press Enter
4. Wait for completion (20-60 minutes)
5. Review results

If SFC found and fixed issues, restart and test stability.

For deeper repairs:

DISM /Online /Cleanup-Image /RestoreHealth

Run this before SFC if the first scan fails to fix problems.

Remove Overclocking

Reset everything to default speeds.

For GPU overclocks:

• Open MSI Afterburner or similar tool
• Click the reset button
• Restart your computer

For CPU overclocks:

• Enter BIOS/UEFI (usually Delete or F2 during startup)
• Load default/optimized defaults
• Save and exit

Stability matters more than benchmark scores.

Update Windows Completely

Missing updates create compatibility gaps.

1. Settings > Windows Update
2. Click “Check for updates”
3. Install everything available
4. Include optional updates
5. Restart when prompted

Check multiple times. Windows often staggers updates.

Reinstall Graphics Drivers Completely

Sometimes you need a nuclear option.

Using DDU (Display Driver Uninstaller):

1. Download DDU from guru3d.com
2. Boot into Safe Mode
3. Run DDU
4. Select your GPU manufacturer
5. Choose “Clean and restart”
6. Install fresh drivers after reboot

This removes all traces of old drivers that might be causing conflicts.

Check Your Power Supply

Insufficient or unstable power causes crashes during GPU load.

Signs of PSU problems:

• Crashes only during gaming or rendering
• System restarts without blue screen
• Crashes more frequent over time
• Electrical smell from PSU

If your PSU is underpowered for your hardware, no software fix will help. Calculate your power needs using an online PSU calculator and upgrade if necessary.

Test Your Graphics Card in Another System

This isolates whether the GPU itself is failing.

Borrow a friend’s computer or use a spare system if available. If crashes follow the GPU, the hardware is faulty. If crashes don’t occur, the problem is elsewhere in your original system.

Scan for Malware

Rootkits and kernel-mode malware can modify system drivers.

1. Run Windows Defender full scan
2. Use Malwarebytes for second opinion
3. Consider offline scanning with Windows Defender Offline

Remove anything detected before trying other fixes.

Advanced Troubleshooting

If basic fixes didn’t work, these deeper solutions might help.

Modify TDR Settings in Registry

Windows has a timeout detection and recovery system. Adjusting it can prevent premature crashes.

Warning: Editing registry incorrectly can break Windows. Back up first.

1. Press Windows key + R
2. Type “regedit”
3. Navigate to: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\GraphicsDrivers
4. Right click in the right pane > New > DWORD (32-bit) Value
5. Name it “TdrDelay”
6. Set value to 8 (decimal)
7. Create another DWORD: “TdrDdiDelay”
8. Set value to 8 (decimal)
9. Restart computer

This gives your GPU more time to respond before Windows triggers a crash.

Disable Fast Startup

Fast Startup can cause driver initialization problems.

1. Control Panel > Power Options
2. Choose what the power buttons do
3. Change settings currently unavailable
4. Uncheck “Turn on fast startup”
5. Save changes
6. Restart normally

Check Event Viewer for Patterns

Windows logs detailed crash information.

1. Right click Start > Event Viewer
2. Windows Logs > System
3. Filter for “Error” level events
4. Look for events near crash times
5. Note any patterns or repeated errors

This reveals if specific applications or services trigger crashes.

Update BIOS/UEFI Firmware

Outdated motherboard firmware causes hardware communication problems.

1. Identify your motherboard model
2. Visit manufacturer’s website
3. Download latest BIOS/UEFI update
4. Follow manufacturer’s flashing instructions carefully
5. Never interrupt this process

Caution: BIOS updates carry risk. Only update if you have recurring unexplained crashes and other fixes failed.

Perform Clean Windows Installation

When all else fails, fresh Windows installation eliminates software corruption.

Before reinstalling:

• Back up important files
• Note your Windows product key
• Save driver installers offline
• List installed programs you’ll need

A clean install takes time but guarantees a stable software foundation.

Preventing Future dxgkrnl.sys Errors

Prevention beats troubleshooting.

Keep drivers updated Set a monthly reminder to check for graphics driver updates. Enable automatic Windows updates.

Monitor system temperatures Check temps monthly. Clean dust every 3-6 months depending on environment.

Use quality power supply Don’t cheap out on PSU. Get 80+ Bronze minimum, from reputable brands.

Avoid aggressive overclocking Mild overclocks are fine. Pushing limits causes instability over time.

Run occasional maintenance Monthly: SFC scan, disk cleanup, temp file removal Quarterly: Full malware scan, driver audit

Maintain good airflow Don’t block vents. Cable management matters. Consider case fans if needed.

When to Seek Professional Help

Some situations need expert intervention.

Get professional help if:

• Crashes persist after trying all fixes
• You smell burning or see visible GPU damage
• System won’t boot even in Safe Mode
• You’re uncomfortable opening your computer
• Hardware is still under warranty

Don’t throw money at random hardware replacements. Proper diagnosis saves money and time.

Frequently Asked Questions

Is dxgkrnl.sys a virus or malware?

No. The legitimate dxgkrnl.sys is a core Windows system file located in C:\Windows\System32\drivers. However, malware sometimes disguises itself with similar names in different folders. If your antivirus flags dxgkrnl.sys or you find it outside the System32\drivers folder, run a full system scan immediately with updated antivirus software.

Can I delete or disable dxgkrnl.sys to stop crashes?

Never delete or disable this file. It’s essential for Windows graphics functionality. Removing it will prevent Windows from displaying anything on your screen. If the file is corrupted, use System File Checker to repair it rather than deleting it. Windows will replace damaged system files automatically with correct versions.

Why do dxgkrnl.sys errors happen only when gaming?

Games stress your graphics hardware more than normal applications. They demand maximum GPU performance, higher temperatures, and more power draw. If your system has borderline stability issues like slight overheating, insufficient power supply, or marginal driver compatibility, these problems only surface under heavy load. This doesn’t mean gaming causes the error, it just reveals existing weaknesses in your setup.

Will upgrading to a new graphics card fix dxgkrnl.sys errors?

Not necessarily. While a failing GPU can cause these errors, most dxgkrnl.sys crashes result from software issues, not hardware failure. Upgrade your graphics card only if you’ve confirmed hardware failure through testing in another system or if other symptoms point to GPU death like artifacts, screen corruption, or complete display failure. Try software fixes and driver updates first.

How do I know if my dxgkrnl.sys error is from RAM or GPU?

Run Windows Memory Diagnostic to test RAM. If it passes, the problem likely isn’t RAM. Then test your GPU under load with monitoring software watching temperatures and for artifacts. RAM errors typically cause varied crash types across different applications. GPU-specific issues mainly crash during graphics-intensive tasks. If crashes happen randomly during light tasks like web browsing, suspect RAM. If crashes occur mainly during gaming or video editing, suspect GPU or drivers.
