NVIDIA nvlddmkm Error — GPU Driver Crash and Display Recovery

Fix NVIDIA nvlddmkm.sys GPU driver crash causing display freezes, black screens, and TDR (Timeout Detection and Recovery) events on Windows. This guide covers everything you need to know about this topic, including common causes, step-by-step solutions, and answers to frequently asked questions.

Here are the key things to understand: nvlddmkm.sys is the NVIDIA Windows kernel-mode driver — crashes in this driver cause display failures. TDR (Timeout Detection and Recovery) resets the GPU when the driver stops responding within 2 seconds. Symptoms include screen freezing, going black, then recovering with 'Display driver stopped responding and has recovered'. In severe cases, the system blue-screens with VIDEO_TDR_FAILURE (nvlddmkm.sys). Overheating, overclocking, power supply issues, and driver bugs are common causes. Understanding these fundamentals will help you diagnose and resolve this issue more effectively.

The most common reasons this occurs include: GPU overheating due to blocked fans, dried thermal paste, or poor case airflow. Unstable GPU overclock pushing core clock or memory beyond stable limits. Power supply not delivering enough wattage or stable power to the GPU. NVIDIA driver version with known bugs for your specific GPU model. Identifying the root cause is the first step toward finding the right solution.

To resolve this, follow these recommended steps: Use DDU (Display Driver Uninstaller) in Safe Mode to completely remove current NVIDIA drivers. Install a known-stable NVIDIA driver version — check forums for your GPU model's recommended version. Monitor GPU temperature with HWMonitor or GPU-Z: should stay below 85°C under load. Remove any GPU overclock using MSI Afterburner — reset to default clocks. Increase TDR timeout: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\TdrDelay (DWORD, set to 8). If these steps do not resolve the issue, consider consulting additional resources or a qualified professional.
