My Game Crashes Every Few Minutes

hollyw26  Thanks for the dxdiag, which lists one crash of the Nvidia graphics driver and two that may be related to your high-end processor and some default overclocking settings.  Let's start with the latter first.  This issue is often fixed with a BIOS update, so please update yours.  I believe this is your model:

You can double-check by clicking This Device and entering your service tag.  If it is the right model, please install BIOS version 2.14.0, which is newer than your currently-installed 2.12.  Then try again to play.

If this doesn't help, please do a clean uninstall and reinstall of the graphics driver, as described here:

If that doesn't help either, please look for new errors in the Reliability Monitor.  Hit Windows key-R and enter "perfmon /rel" without quotes, and you'll see a chart of errors and updates with a column for each day.  Today is on the right.

Look for errors that happened at exactly the time of any Sims 4 crash from after you updated the BIOS.  (I don't need to see the older ones.)  If you find one, double-click it to see more details, then copy that info and paste it into a reply here.  I'd like everything you find except for exact duplicates.  If you don't see a new error, check back in an hour or so—the Reliability Monitor doesn't always update right away.
