The Sims 4 keeps crashing at loading screens

nini0045  The Sims 4 crashes in your dxdiag look like the typical crashes related to high-end Intel processors that the motherboard may overclock by default.  This is sometimes fixed with a BIOS update, but it looks like you already have the newest version installed.  So please boot into BIOS and disable CPU Turbo Boost, which will be somewhere under Advanced settings.

Separately, are you getting BlueScreens while playing?  I see several in your dxdiag, two different kinds, but not ones that make it obvious exactly where the problem is.  (One has to do with accessing paged memory incorrectly, but that doesn't specify what process did so.)  I can try to help with these too if you want.  In that case, please open C:\Windows\Minidump and upload the most recent three or four files.  You'll need to copy them where they are, paste them onto your desktop (or wherever you prefer), zip them together, upload the .zip to a third-party filesharing site, and link it here.
