Re: unsupported video card
@Magicalsimmer07 Somehow your graphics driver was uninstalled, and your computer is now using the Microsoft Basic Display Adapter, which Sims 4 doesn't support. So the simple fix would be to reinstall the Nvidia driver. I can't tell what GPU you have from your dxdiag—it's not showing up at all—but if it's 900-series or newer (so anything released in the last seven or eight years), the newest driver should work:

However, before running the driver, please see whether your GPU is showing up at all. Hit Windows key-X, select the Device Manager, expand the Display adapters section, and look for your Nvidia card. If it's not there, please let me know.
