In the past two days, due to some reasons, I uninstalled the original independent graphics driver of the previous laptop, the computer Dell The specific manifestation is that when you install the driver, it keeps prompting "Graphics driver installation failed." Later I read a blog that solved this problem. If you want to uninstall the original driver and reinstall it, you can try this ():

1. Uninstall the original driver in Control Panel->Programs and Features.Uninstall the PhysX system software and graphics driver

2. Use Computer Manager (or other cleaning software) to scan and clean garbage

The first two steps are to completely clear the previous version of the driver. Next, start installing the new driver:

3. Go to the official website to download the driver. This driver must correspond to the driver of the graphics card installed on your computer. For example, for the independent graphics card driver of my computer, I need the driver of gtx 960M.

4. Run the downloaded driver exe file. Do not do anything after checking the system compatibility. Right-click "This PC" and select "Manage". Open "Services" under "Services and Applications" and click Setup. , right-click on these three services one by one, start them, go back to the driver installation program just now, go to the next step, and select "Custom Installation". You don't need to use the things installed above. Just use the default ones. There is a "Clean Installation" option below. box, you need to check this, and then take the next step to install it successfully.
