Game Crashes at Startup

RoseKitsude  Some of the errors in your dxdiag are serious crashes of the graphics driver, which would explain the game crashing at startup.  So please do a clean uninstall and reinstall of the driver:

Your dxdiag also lists a couple other serious errors, including some BSODs.  Are you seeing those when trying to play Sims 4, or in other contexts?  They're definitely happening, but sometimes the actual BlueScreen only appears for a very short amount of time, so it's easy to miss.  Let me know if your computer ever shuts down unexpectedly and in what context.
