NIGHT-XZ0 Did you use Display Driver Uninstaller to remove the driver? If not, please do so now. Other methods are mostly but not completely reliable. If that still doesn't help, please post a new dxdiag.
Please also 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.
I'd ideally like two or three of these, or a note that the same error happened two or three times, all after you've clean-uninstalled and reinstalled the graphics driver.
