Seems your graphic card is an entry level card and might not be powerful enough for the game.
Did you try lowering all graphics settings in game ?
Could you post your Computer's DxDiag?
To gather a DxDiag on your computer, please follow the steps here: http://answers.ea.com/t5/The-Sims-3/HOW-TO-DxDiag-for-Sims-3-PC-Only/td-p/1049584/
Is it only CAS that crashes and does it happen each time you play your game or only occasionally ?
