Standard driver uninstallers leave registry keys and DLL hooks behind. Using DDU in Windows Safe Mode completely purges all graphics driver remnants.
Why This Problem Happens
- Overwriting GPU drivers repeatedly corrupts the shader cache and driver store.
- Switching from NVIDIA to AMD GPU without purging old kernel hooks.
Step-by-Step Troubleshooting Procedure
Step 1: Download DDU and Latest Driver Installer
Objective: Prepare offline installer files.
- Download Display Driver Uninstaller (DDU) from Wagnardsoft.
- Download the latest certified driver installer from nvidia.com or amd.com, but do NOT run it yet.
Step 2: Disconnect from the Internet and Boot into Safe Mode
Objective: Prevent Windows from auto-installing generic drivers.
- Unplug Ethernet or disconnect Wi-Fi.
- Hold Shift while clicking Restart in Windows menu > Troubleshoot > Advanced Options > Startup Settings > Restart > Press 4 for Safe Mode.
Step 3: Run DDU and Select “Clean and Restart”
Objective: Execute deep system scrub.
- Launch DDU in Safe Mode, select device type “GPU” and your vendor (NVIDIA/AMD).
- Click “Clean and restart”. Windows will reboot into normal mode.
- Run your downloaded driver installer and check “Perform a clean installation”.
Verified Troubleshooting Tips
- Keeping internet disconnected until the fresh driver is installed prevents Windows Update from forcing a generic driver onto your GPU.
