Fix Video TDR Failure in Windows 10

Video TDR Failure in Windows 10 usually means the graphics driver or GPU stopped responding and Windows could not recover it in time. Start by restarting the PC and updating or rolling back the graphics driver; if the error returns, check Windows updates, overheating, and hardware before trying more disruptive repairs.

What the Video TDR Failure Means

TDR stands for Timeout Detection and Recovery, a Windows graphics feature. Windows monitors the graphics processing unit (GPU); if it stops responding for too long, Windows attempts to reset the graphics driver rather than leaving the computer frozen. When recovery fails, Windows may display a blue screen with the stop code VIDEO_TDR_FAILURE. The crash screen may also name a file such as nvlddmkm.sys, atikmpag.sys, or igdkmd64.sys, which can point to the graphics-driver family involved. A filename is a clue, not proof that the driver file itself is defective.

Common triggers include a damaged or incompatible driver, a recent driver update, excessive GPU temperature, unstable overclocking, and, less often, a failing graphics card, power supply, or other hardware. A single crash does not establish which cause applies, so work through reversible checks before replacing parts or changing system settings.

Try These Fixes in Order

Restart and note the pattern. If Windows starts normally, save your work and record what you were doing when the crash happened. A failure only during a particular game or graphics-heavy task suggests a load-related issue; crashes at idle or during startup may point elsewhere.
Install Windows updates. Open Settings > Update & Security > Windows Update and select Check for updates. Install available updates and restart. Windows Update can supply compatibility and system fixes, though it may not offer the newest graphics driver.
Update the graphics driver. Right-click Start, choose Device Manager, expand Display adapters, right-click the graphics device, and choose Update driver > Search automatically for drivers. If this finds nothing, check the support site for the computer maker or graphics-device maker and select a driver compatible with your exact Windows 10 version and hardware. On laptops with switchable graphics, prefer the laptop maker’s guidance when available.
Roll back a recent driver change. If the problem began immediately after a driver update, open the device’s Properties in Device Manager, select the Driver tab, and choose Roll Back Driver if the button is available. Restart and see whether the crashes stop. The option may be unavailable if Windows has no earlier driver stored.
Remove overclocking and check temperature. Return any GPU, CPU, or memory overclock to its normal settings, including changes made through tuning software. Make sure vents are not blocked and fans can turn. If crashes happen after sustained gaming or rendering, heat is worth investigating; do not open a power supply or work inside a computer while it is connected to power.

Reinstall the Driver If Updating Does Not Help

A corrupted installation can persist after an ordinary update. In Device Manager, right-click the display adapter and select Uninstall device, then restart Windows. Windows may install a basic or previously available driver automatically. If it does not, use the computer or graphics-device maker’s support instructions to install a compatible driver.

Use caution with any option to delete driver software: removing the package can leave Windows with limited display support until a suitable driver is installed. Before uninstalling, download the correct replacement driver and save it locally, particularly if the affected PC depends on that graphics adapter for its display. Avoid third-party driver-updater utilities; they can install mismatched software and make diagnosis harder.

Check System Files and Hardware

If driver changes do not resolve repeated crashes, check Windows system files. Open Command Prompt as an administrator, run DISM.exe /Online /Cleanup-image /Restorehealth, wait for it to finish, then run sfc /scannow. Restart when the checks complete. These tools repair certain Windows component or system-file problems; they do not repair a defective GPU.

Also consider whether the issue followed a hardware change, a fall, heavy dust buildup, or a period of overheating. A desktop graphics card may need to be checked for secure seating or power connections, but only attempt internal work if you know how to shut down and unplug the computer safely. For a laptop or unfamiliar system, use a qualified repair service rather than disassembling it. If the PC crashes across multiple applications, shows visual artifacts, or continues failing with a known-compatible driver, hardware testing may be needed.

When Windows Will Not Start

If the blue screen prevents normal sign-in, enter Windows Recovery Environment. Windows may open it after repeated interrupted startup attempts; you can also use Windows installation media and choose the repair option. From recovery, try Troubleshoot > Advanced options > Startup Settings > Restart, then select Safe Mode. Menu wording can vary slightly.

In Safe Mode, Windows loads a limited set of drivers, which can help you remove or roll back a recent graphics driver. If the PC began failing after a recent Windows change, System Restore may be available under Troubleshoot > Advanced options. It restores system files and settings to a restore point; it is not a substitute for backing up personal files. Do not choose reset or reinstall options until you have considered how to preserve important data.

Common Misconceptions and What to Avoid

Changing the TDR timeout in the Windows registry is often suggested online. Increasing the timeout can hide a symptom or delay a crash, but it does not fix a driver or hardware problem and may complicate troubleshooting. Avoid registry edits unless you have a specific, well-supported reason and understand how to restore the original setting. Likewise, repeatedly reinstalling Windows is not a sensible first response to a graphics error.

The named driver file does not automatically identify a faulty component, and a blue screen does not always mean the GPU must be replaced. Use the timing of the crashes, recent changes, temperature behavior, and results from driver rollback or reinstallation to narrow the cause. If there are repeated crashes or signs of physical damage, back up important files and seek hardware diagnosis.

Frequently Asked Questions

Can a graphics driver cause Video TDR Failure?
Yes. An incompatible, damaged, or recently updated graphics driver is a common cause. Updating or rolling back the driver is a useful early test, but overheating or hardware faults can produce the same stop code.

What does nvlddmkm.sys mean?
It is a file associated with a graphics-driver stack. Its appearance can help identify where Windows detected the failure, but it does not by itself prove that the driver file—or the graphics card—is the root cause.

Will reinstalling Windows fix Video TDR Failure?
It might help if Windows itself is damaged, but it is a major step and will not fix a failing GPU or overheating. Try driver, update, and system-file checks first, and back up important files before any reset or reinstall.

Should I increase the TDR delay in the registry?
Usually not as an initial fix. A longer delay can mask a timeout without addressing its cause. Prefer supported driver and hardware checks, and avoid registry changes unless directed by reliable, situation-specific guidance.

Does this stop code mean my graphics card is dead?
No. Driver issues and heat can also trigger it. Persistent crashes with a compatible driver, especially alongside artifacts or failures under load, make hardware diagnosis more important but are not conclusive on their own.
