(help) World Adventures Loading screen crashes

Good Day to all!

I am having problems with my sims 3 when my sims will travel to Shang simla, champ les sims, and Al Simhara. The loading screen of World Adventures will load for a bit and then the music will stop while loading and then it will crash. I have tried reinstalling everything, disabled programs running on the background, reinstalled my Operating system, Tried the sims 3 ultimate fix, DEP solution, updating my drivers, tried base game and WA only installed, and my game is always updated to the latest game update. Creating a new game will help and will work without any problems for just a while but when my sims started travelling to the places of WA after multiple times, the loading screen of WA will crash. I have created a new game a lot of times already. I don't know what to do next. As what I know, my laptop specs passed the minimum requirements for the sims 3. I have core i3 2.27ghz, 500gb hdd, 2gb ram, and ati mobility radeon hd 5470. The only game that I have is the sims 3 with all expansions and stuff pack but no CC and mods.

//EDIT

In addition to that, when installing sims and all its expansions and
stuff packs, I am following how to install the sims 3 thread. Thanks in
advance for any help!

Good day to you too,

Just to be sure, please run this test to see whether your PC can run the game: http://www.systemrequirementslab.com/cyri/

Thanks! I checked the link that you gave and it's saying that my computer's specs passed the requirement for the game.

Hello,

Can you tell me which expansions you have installed at the moment?
