How to Clean Install GPU Drivers with DDU (Step by Step)
Published
On this page
Normal driver updates install on top of the old ones, and the leftovers cause exactly the problems people blame on the new driver: random stutter, crashes, FPS regressions. A DDU clean install wipes the slate. It takes 15 minutes and fixes a remarkable share of “my game suddenly runs badly” cases.
Driver problems survive driver updates. They don’t survive DDU.
Before you start
- Download your new driver first — you’ll be offline during the process:
- NVIDIA: the Game Ready/Studio driver for your card from the official site.
- AMD: the Adrenalin package for your card.
- Download DDU from its official source (Wagnardsoft) and extract it.
- Disconnect from the internet (unplug ethernet / disable Wi-Fi) so Windows Update can’t sneak its own driver in mid-process.
Step 1: boot into Safe Mode
- Win+R →
msconfig→ Boot tab → tick Safe boot (Minimal) → restart. - (Remember to untick this after the process — step 4.)
Safe Mode ensures no driver files are in use while DDU works.
Step 2: run DDU
- Launch DDU. Select device type GPU and your vendor (NVIDIA/AMD/Intel).
- Click Clean and restart.
- DDU removes the driver stack and reboots. Your screen will look low-res — that’s normal.
Step 3: install the new driver
- Still offline, run the driver installer you downloaded.
- NVIDIA: choose Custom → Clean installation and untick components you don’t use. AMD: Full Install.
- Reboot when prompted, reconnect to the internet.
Step 4: restore your settings
A clean install resets everything, so redo your tuning:
- NVIDIA Control Panel settings or AMD Adrenalin settings
- G-Sync/FreeSync setup
- Any undervolt or overclock profile in Afterburner
- Untick Safe boot in

When DDU is the right call
| Symptom | DDU? |
|---|---|
| Stutter/crashes started near a driver update | Yes |
| FPS clearly lower than weeks ago, same settings | Yes |
| Swapped NVIDIA ↔ AMD | Always |
| After a major Windows feature update with GPU weirdness | Yes |
| Routine monthly driver update, no problems | No — normal install is fine |
If a clean install doesn’t fix the stutter, the cause is elsewhere — work through the shader cache clear and the lag spike guide next, and verify with a frame-time overlay.

Frequently asked questions
What does DDU actually do?
Display Driver Uninstaller removes every trace of GPU drivers — files, registry entries, leftover services — that the normal uninstaller misses, so the new driver installs onto a clean slate.
When should I use DDU instead of a normal driver update?
After stuttering, crashes or FPS regressions that appeared around a driver update, when switching GPU brands, and after major Windows feature updates. For routine updates a normal install is fine.
Is DDU safe to use?
Yes, it is a long-standing community-standard tool. Run it in Safe Mode with the internet disconnected, and the worst case is simply reinstalling the driver again.
Why is my screen low resolution after running DDU?
That is expected — Windows falls back to a basic display driver until you install the real one. Install your downloaded GPU driver and resolution returns to normal.
