Ultimate GPU Driver Cleanup Guide (DDU + Fresh Install) | For New GPU Upgrades

If you're upgrading your graphics card or dealing with weird performance drops, crashes, stutters, or driver issues, doing a proper clean GPU driver reinstall can save you a ton of headaches. I just upgraded from a 4070 Super to a 5070 Ti and walked my brother-in-law through the exact process I’ve done for years: using DDU (Display Driver Uninstaller) to completely remove old drivers, reboot clean, and install the latest NVIDIA drivers from scratch.

I also cover another step I always do that most people skip: using CRU (Custom Resolution Utility) to delete the 4096×2160 resolution. That mode doesn’t play nicely with certain games, DLSS, or FSR, and removing it helps prevent scaling issues, incorrect fullscreen behavior, and random visual glitches.

Whether you're installing a new GPU during Black Friday/Cyber Monday or troubleshooting your current setup, this full “super-duper GPU cleanup” routine will help you start fresh and avoid common driver conflicts.

What this video covers:
• Downloading and installing DDU and CRU
• Booting into Safe Mode using DDU
• Completely removing old GPU drivers
• Installing NVIDIA drivers the right way
• Using CRU to remove the problematic 4096×2160 resolution
• Fixing driver corruption, scaling issues, and weird game behavior
• Tips for smoother upgrades and better stability
