4. Follow the on-screen instructions to remove your graphics driver.
5. Restart your computer.
6. Install the latest driver from the manufacturer’s website.

Finding the Right Driver

After uninstalling the old driver, you need to install a new one. You have two primary options:

Windows Update: Windows will often automatically install a basic, compatible driver. This is generally sufficient for basic display functionality, but may not provide the best performance for games or other demanding applications.
Manufacturer’s Website: Downloading the latest driver from NVIDIA, AMD, or Intel ensures you have the most up-to-date and optimized driver for your specific graphics card.
- NVIDIA: https://www.nvidia.com/Download/index.aspx
- AMD: https://www.amd.com/en/support
- Intel: https://www.intel.com/content/www/us/en/download-center/home.html

Common Mistakes

Downloading Drivers from Unofficial Sources: Only download drivers from the official websites of NVIDIA, AMD, or Intel. Unofficial sources may contain malware.
Installing the Wrong Driver: Make sure you download the correct driver for your graphics card model and operating system.
Not Uninstalling the Old Driver Properly: Leaving leftover files from the old driver can cause conflicts and performance issues.
Forgetting to Restart: Restarting your computer is crucial after installing or uninstalling graphics drivers.

Advanced Considerations

Clean Installation: When installing drivers from the manufacturer, choose the “Clean Installation” option (if available). This removes all previous driver settings and profiles.
Driver Rollback: If a new driver causes problems, you can roll back to a previous version in Device Manager.
Driver Sweepers: Besides DDU, other driver sweeper utilities exist, but DDU is generally the most reliable.

When Reloading Doesn’t Fix the Problem

Sometimes, reloading your graphics drivers won’t resolve the issue. In these cases, consider the following:

Hardware Issues: The problem might be with your graphics card itself. Test the card in another computer or try a different graphics card in your system.
Operating System Problems: A corrupt operating system can cause driver conflicts. Consider reinstalling Windows.
Power Supply Issues: An insufficient or failing power supply can cause instability, especially with high-end graphics cards.
Overheating: Overheating can cause graphics card malfunctions. Ensure your cooling system is adequate.
