What is DDU and why use it?

Display Driver Uninstaller completely removes all NVIDIA driver files and registry entries. Regular uninstall leaves remnants that can cause conflicts.

Can this mean my GPU is dying?

Possibly, especially with artifacts or crashes across multiple driver versions. But try driver solutions first — most cases are driver bugs, not hardware failure.

Windows nvlddmkm.sys BSOD — NVIDIA Display Driver Crash

Criticaldriver

Overview

The nvlddmkm.sys BSOD is caused by NVIDIA's display kernel mode driver crashing, triggering VIDEO_TDR_FAILURE or other stop codes during graphics operations.

Key Details

nvlddmkm.sys is NVIDIA's Windows kernel mode display driver
Most common stop code: VIDEO_TDR_FAILURE (0x00000116) naming nvlddmkm.sys
TDR (Timeout Detection and Recovery) triggers when GPU does not respond within 2 seconds
Can cause black screen, display freezing, or full BSOD
Extremely common across all NVIDIA GPU generations

Common Causes

NVIDIA driver bug in the current version
GPU overheating causing the driver to hang
Unstable GPU overclock or memory overclock
Power supply not providing enough power to the GPU under load
Driver conflict with Windows Fast Startup or hybrid sleep

Steps

1Download Display Driver Uninstaller (DDU) and run it in Safe Mode to completely remove NVIDIA drivers
2Install the latest NVIDIA Game Ready or Studio driver from nvidia.com
3If latest driver crashes, try an older stable version from the NVIDIA driver archive
4Monitor GPU temperature with GPU-Z — should stay under 85°C under load
5Disable Windows Fast Startup: Control Panel > Power Options > Choose what the power buttons do > uncheck 'Turn on fast startup'
