unrecognized graphics card

Recently, I finished building my new pc I went ahead and downloaded Sims 4, and the first thing to show up was that the game did not recognize my graphics card. I've reviewed a few of the discussions on here as well as searched online and on social media, and one of the discussions suggested checking the system file checker to see if there's anything that needs to be repaired or is missing. However, I didn't find anything wrong. However, the problem persists with the game not recognizing my graphics card, and it's also causing my game to freeze intermittently, as well as load more slowly. Please guide me on how to fix this issue.
