PC= personal computer. So I’m assuming you need the graphics card in your desktop and not the laptop.
but you got it :). you have to take off the central processing unit’s shell and you will see ports. the graphics (video/audio) cards can be placed in any of the ports depending on your model.Â
[You may or may not need tiny screws to secure the card within the port. Screws aren’t entirely necessary but mine happen to come with them. Ports are snug, so the card will be secure on it’s own].
Once the CPU shell is back on, make sure you plug the monitor into the video port in the back of the CPU.
Hope that helps smt smt
