Re: sims 4 keeps crashing in build mode

You do not have enough RAM. While you do have 4GB half of that is used by the builtin graphics so you end up with too little for the game. Try turning graphics down to low and see if that will let you play. Also even though laptops are not very upgradeable in most cases it is possible to add more RAM. I suggest you look into this. Also your CPU is well below minimum requirements. However if you upgrade with more RAM keep Graphics at low and do not try to create big dogs it might work OK. Do not plan on getting the latest expansions already cats & dogs are too taxing for this laptop.
