What must you do to ensure the operating system recognizes a third-party graphics card?

To ensure that the operating system recognizes a third-party graphics card, it is essential to install the appropriate drivers for that graphics card. Drivers serve as a communication bridge between the operating system and hardware components, in this case, the graphics card. When a new graphics card is installed, the existing operating system may not have the necessary drivers to recognize and utilize the card's full capabilities. By installing the correct drivers provided by the graphics card manufacturer, you enable the operating system to identify the hardware and leverage its features effectively, such as enhanced graphical performance or advanced display options.

Removing all other hardware is unnecessary and impractical, as modern operating systems are designed to manage multiple components simultaneously without conflict. Reinstalling the operating system would be a drastic measure that is not typically required just to get a new graphics card working. Disabling all system utilities does not contribute to recognizing hardware and could create additional issues by turning off essential monitoring and management tools. Thus, the installation of the correct drivers is the vital step in ensuring recognition of the graphics card by the operating system.
