Sims 2 takes forever to load and then crashes?

I have sims 2 installed with mansion and garden stuff, nightlife, and glamour stuff.. I had to uninstall allllll of my sims games toda because it wouldn't load so I did that. Now I have just these installed (I have every sims2 game.. just not installd on my computer) so it takes a while to load and then when it does I click a neihborhood, that loads, then it goes black for a little bit and crashes. I tried killing processes in task manager. Nothings working!! Helpme please! I'm running windows 7 and I don't have too many things installed on my laptop I've never had this problem before help!!!
