# I had a previous driver or GPU installed. Will that cause issues?

Yes.

If you previously had a different graphics card or driver installed, we recommend removing the previous graphics drivers before installing the drivers for your new graphics card.

**Use Display Driver Uninstaller**

Download the latest version of Display Driver Uninstaller (DDU) from the developer's website:

[Download Display Driver Uninstaller](https://www.wagnardsoft.com/forums/viewtopic.php?t=5660&utm_source=chatgpt.com)

**Before running DDU**

Restart your computer in **Safe Mode**.

Once the computer starts in Safe Mode, open Display Driver Uninstaller.

Select **GPU** and then select the brand of the previous graphics card driver on the left side of the program.

Click **“Clean and Restart.”**

Display Driver Uninstaller will remove the previous graphics drivers and restart the computer when the process is complete.

After the computer restarts, install the latest driver for your current graphics card.

**Important**

Only remove the drivers for the previous graphics card. Make sure you select the correct GPU brand in Display Driver Uninstaller before choosing **“Clean and Restart.”**
