Game lag or stop completely

shaquanta1996​  Please provide a dxdiag.  Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop.  From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.

Please also let me know whether the game lags in a new save with new sims in a default EA house.  This is just for comparison's sake; you don't need to abandon your current saves.
