Re: Re: Sims 3 crashing before opening at all

@shannara76  Thanks for the dxdiag, which shows that you don't have an Alder Lake processor or another model that's similarly affected.  I've therefore split your post into its own thread since the root cause here is different even if the effect is the same.

To start, please move the entire Sims 3 user folder out of Documents > Electronic Arts and onto your desktop.  If the folder copies instead of moving, or you get an error when trying to move it, stop here and let me know.

Otherwise, when open the launcher, a clean folder will spawn with no content.  (Your saves and other content will be intact in the folder you moved but temporarily not read by the game.)  Don't add anything to the new folder yet; just let me know whether you can get far enough to start a new save and play in live mode for a bit.

If you still can't play, 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 attempt to launch Sims 3, specifically after you've moved the user folder.  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.
