@limitedvaeh Your dxdiag lists a number of crashes of the Nvidia graphics driver, so please do a clean uninstall and reinstall of the driver, as described here:

You can get a fresh copy of the newest Nvidia driver here:

If you get another shutdown, 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 crash, specifically after reinstalling the driver. 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.
If you still don't see an error, please download hwinfo (it's free) and open it before launching Sims 4, then check your CPU and GPU temperatures periodically. Let me know the maximum you see before your computer crashes. I'm interested in the highest CPU core temp and the GPU core temp.
