After downloading Expansion P.- Error occurs "Sims3Launcher has stopped working

Hi again,
I have my original Sims 3. It was working well with Katy Perry and Seasons Expansion Packs. No errors or anything else. Then, because of the unbreakable "I want all the Ex. Packs feeling" in me I started to download the other Expansion Packs. I downloaded Master Suite and Diesel Stuff. After downloading these Ex. Packs my game became unable to start. It started to give me this "Sims3Launcher stopped working" error. I uninstalled all E.Packs and the base Sims3 to check where the problem is. I installed Sims 3 and checked if it is working fine. Yep It was working. Then I started to install the E. Packs. I got 'Sims3Launcher error'. I searched all the topics that look like same in this site, tried to do what u suggested but nothing changed. I downloaded game booster, write some codes to Command Prompt. My game was working perfectly with Katy Perry and Seasons but with the additional E.Packs it doesn't work. Maybe more than 2 Expansion Pack is too much for my laptop. Is there anything u can do to help me?
