GPU—how do I check if the graphics card driver is installed correctly?

By using the Windows operating system, you may right-click “This PC”, and click “Manage”, then enter “Device Manager”, and select “Display Adapters”. Then, you may find the GPUs of your device.

There will NOT be a yellow exclamation mark in the graphics card icon when the driver is installed correctly. The presence of a yellow exclamation mark means that the driver is not yet installed or signed (AMD graphics cards are required to run a signature program after the installation of the graphics card driver). You may need to reinstall the graphics card driver or run the signature program (for AMD Graphics cards).
