My Game Keeps Freezing and Failing to Respond

@zummbutter  Do you get an error message, and if so, what does it say?  A screenshot would be helpful, especially if there's an error code included.

Please try playing in a clean user folder.  Move your entire Sims 4 folder out of Documents\Electronic Arts and onto your desktop, and when you launch the game, a clean folder will spawn with no content.  Don't add anything to it yet; just see whether the game still crashes when you're playing a new save.  Let me know either way.

If you do get another crash, please run a dxdiag and attach it to a post.

@Keilene  Most of the above applies to you as well, although I'd like to hear whether the game lags in a new save in a clean folder.  If so, I'd like to see a dxdiag.
