The steps to reinstall the graphics card driver include: 1. Confirm the graphics card model and driver status, enter dxdiag through Win R to view the device information and test the graphics function; 2. Use the device manager to uninstall the driver, check the delete driver software and restart the system to automatically install the basic driver; 3. Go to the manufacturer's official website (NVIDIA/AMD/Intel) to download the latest dedicated driver or use DDU to deeply uninstall it before installing it; 4. Check whether the graphics card settings in the BIOS are normal and make sure that the integrated graphics card is not disabled. Follow the above process to complete the complete reinstallation of the graphics card driver.

Reinstalling the graphics card driver is the first step to solve many graphic display problems, such as black screen, frizzy screen, game crashes or performance degradation. It is actually not difficult to directly enter the system. The key is to confirm the hardware model and installation method.

Confirm the graphics card model and current driver status

Before starting, first know which graphics card you are using (NVIDIA, AMD, Intel integrated graphics card, etc.) and the current driver version number.
You can check this way:

• Press Win R , enter dxdiag , and enter
• Look at the "Device" section in the "Display" tab, which contains the graphics card name and driver version

If you are not sure if it is a driver problem, you can also click "Test DirectDraw/Direct3D" here to see if there are any obvious exceptions.

Uninstall and reinstall the driver through Device Manager

This is the most basic method, suitable for most cases:

1. Right-click on the Start menu and select "Device Manager"
2. Expand Display Adapter
3. Right-click your graphics card device → “Uninstall device”
4. Check "Delete driver software for this device" (if this option is available) → OK
5. After the uninstallation is completed, restart the computer and the system will try to automatically install the basic driver.

Note: If you just want to update rather than completely reinstall, you can click "Scan to detect hardware changes", but it is recommended to thoroughly clean up old drivers with third-party tools.

Use the manufacturer's official website or driver management tool to install the latest version

The automatic installation of the base driver may not be up-to-date and may also be limited in functionality. Recommended to download dedicated drivers on the official website:

• NVIDIA: GeForce Experience
• AMD: Radeon Software
• Intel: Intel Driver & Support Assistant

Or use driver management software to process it in one click, such as DDU (Display Driver Uninstaller) for deep uninstallation, and then reinstall the official driver.

Special reminder: Problems with integrated graphics card settings in BIOS/UEFI

Some laptops have problems switching dual graphics cards, or the graphics card device is suddenly not found, which may be because the BIOS settings are wrong.
The method to enter the BIOS is usually to press the F2/F10/Delete key when powered on, and find options like "Primary Display" or "iGPU Mode" to ensure that it is not disabled.

In addition, some branded phones (such as Lenovo and Dell) come with driver recovery tools, which can be found in the control panel or pre-installed software, and can also quickly restore the graphics card driver.

Basically these steps. Although it seems a bit too much, you will know the process by following it once. The key is to uninstall it and then install the new driver.
