Display Driver Uninstaller (DDU) removes every trace of your GPU driver from Windows — registry entries, leftover files, and services that Windows’ built-in uninstaller misses. It’s the right starting point when troubleshooting GPU crashes, black screens, artifacting, or when switching between GPU brands.

When to Use DDU

Switching from NVIDIA to AMD (or vice versa)
Updating to a new major GPU driver version
Troubleshooting: crashes, TDR errors, black screens, artifacting
After a Windows reinstall that retained old drivers
Installing a new GPU

Download DDU

Get it from guru3d.com/files/display-driver-uninstaller-download — never download from third-party sites. DDU is updated frequently; always use the latest version.

Preparation

Before running DDU:

Download the new GPU driver from nvidia.com or amd.com — have it ready but don’t install yet
Know your current GPU model (check Device Manager or GPU-Z)
Save any work — DDU will restart your PC

Step 1: Boot into Safe Mode

Running DDU in Safe Mode prevents Windows from reinstalling the driver during the process.

Method 1: Settings (easiest)

Settings → System → Recovery → Advanced startup → Restart now
Troubleshoot → Advanced options → Startup Settings → Restart
Press 4 for Safe Mode

Method 2: msconfig

Win + R → msconfig → Boot tab
Check Safe boot → Minimal
Apply and restart
(Remember to uncheck this after DDU is done)

Method 3: Hold Shift while clicking Restart

Step 2: Run DDU in Safe Mode

Extract Display Driver Uninstaller.exe from the downloaded zip
Run it as Administrator
In DDU’s interface:
- Select device type: GPU
- Select device: choose NVIDIA, AMD, or Intel from the dropdown
Click Clean and restart

DDU removes:

Driver files from System32\DriverStore
All registry keys for the GPU driver
Leftovers from previous driver versions
Audio component drivers (NVIDIA HDMI audio, AMD HDMI audio)
PhysX, GeForce Experience, Radeon Software components

The system restarts, and Windows boots with the basic Microsoft display driver (800×600 or basic resolution).

Step 3: Install Fresh Driver

After reboot (normal mode):

NVIDIA

Run the downloaded installer
Choose Custom (Advanced) installation
Check Perform a clean installation — removes GeForce Experience leftovers
Deselect components you don’t need: GeForce Experience, NVIDIA Audio, PhysX (if you don’t use it)

AMD

Run the AMD Software: Adrenalin installer
Choose Install or Factory Reset option
The installer handles a clean installation automatically

DDU Settings to Know

In the DDU settings panel (gear icon):

Remove C:\AMD or C:\NVIDIA folders: yes, clears driver extraction folders
Remove GeForce Experience: yes if you don’t use it
Remove Radeon Software: yes for full AMD cleanup
Create a restore point: enabled by default, good safety net

After Installation: Verify

Check Device Manager → Display Adapters — should show your GPU with the correct driver version
Open GPU-Z or NVIDIA Control Panel / AMD Software to confirm driver version
Run a quick benchmark (3DMark, Unigine Superposition) to confirm stability
Check HWiNFO64 temperatures are normal

Switching GPU Brands

When going from NVIDIA to AMD or AMD to NVIDIA:

Physically remove the old GPU
Boot without a dedicated GPU (use integrated graphics if available)
Run DDU to remove the old brand’s driver completely
Shut down, install new GPU
Boot and install new driver

This prevents driver conflicts that cause BSODs or boot loops.

Common Driver Issues DDU Fixes

Symptom	Likely Cause
Black screen after driver update	Corrupted driver state
TDR errors (display driver stopped)	Old driver fragments
Artifacts / screen flickering	Mixed driver version files
Game crashes after GPU swap	Wrong brand’s driver still present
BSOD on boot with new GPU	Previous driver conflicting

DDU takes 5 minutes but saves hours of troubleshooting. Make it standard procedure any time you’re dealing with GPU driver problems or upgrading hardware.
