deshun24 As a test, please try playing in a clean user folder. Move the entire Sims 4 folder out of Documents > Electronic Arts and onto your desktop. When you launch the game, a clean folder will spawn with no content. (Your saves and other content will be intact in the folder you've moved but temporarily unread by the game.) Don't add anything to the new folder yet; just start a new save and see how it runs.
If you get another crash, please provide a dxdiag. Hit 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 camera (Insert Media) icon included with the other formatting buttons.
Separately, when you try to send your sim to college, are you splitting the household? That's a known issue, and if it's your issue too, please use the master bug thread:

EA is looking for saves, as noted in the accepted solution, so please provide yours if you're willing.
