Whole pc crashing since last update

meadowtrip​  I apologize for the late reply; I've had trouble keeping up with the forums lately.

At any rate, your dxdiag doesn't list any Windows errors at all, which is not normal.  Even a fresh install of Windows usually has one or two.  So the data is getting deleted, or the dxdiag program can't read it, or there's some other reason it's not being recorded.  If you're using an app that deletes temp files, it could be deleting this data too, so please disable it while troubleshooting since we need that data.

Aside from that, try again to play, and when the game crashes, 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.
