sims 4 crashes my pc, constantly crashing

craftysimss​  Did you ever do a clean reinstall of the graphics driver?  I ask because most of the Windows errors in your dxdiag are crashes of the driver, and one of those could certainly take Sims 4 down with it.  So that's the place to start.

Even if you did a clean reinstall of the driver, I'd suggest doing so again, and this time, going back to an older driver just in case the newest one doesn't get along with Sims 4.  I've seen some reports that the next-newest driver could be an issue, although nothing definitive.  But since you need to do a clean uninstall anyway, and it's easy to update an older driver to a new one, please try the driver from mid-March.  You can get it here:

Choose Game Ready Driver as the Download Type to be able to go back further.  Please use this technique to clean-uninstall your current driver:

If you get another crash, 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 an error that happened at exactly the time of your most recent Sims 4 crash.  If you find one, double-click it to see more details, then copy that info and paste it into a reply here.  If you don't see a new error, check back in an hour or so—the Reliability Monitor doesn't always update right away.
