Sims 3 not responding ?

Hey, so a few days ago I solved my crashing problem with help from the official tech team who instructed me to enable the 3gb extension. After reinstalling the game for unrelated reasons, I did as instructed and the game worked perfectly fine. No more crashing, it was even smoother and a lot faster than before.
A couple of days ago I downloaded a bunch of CC -a lot of it, actually. After that I launched the game. Only a black screen showed with the cursor loading, I waited for a while but nothing happened. Tried to click out of the window (my task bar was still showing) but everything was frozen although I could still move the cursor. I had to open the task manager to shut down the process since it wasn't responding.
I thought maybe some of the CC I downloaded was corrupted or maybe there was just too many files, so I moved the Mods folder out of the Sims 3 folder and re-tried to launch the game but it still wouldn't work. I retried many times, launching the game through TS3W.exe, TS3.exe, the launcher, I tried the Ultimate Fix crack and the Island Paradise (my last add-on) crack but it still wouldn't work. I don't think the problem is coming from my graphic card this time since the 3gb extension thingy solved the crashing. I am completely clueless as to what the problem could be and I have no idea what to do. Can anyone suggest something before I try to uninstall and reinstall everything ? (I have 7 add-ons so it's a bit of a pain lol) Thank you ;_;

Hello,

I did as instructed (I renamed the Sims 3 folder as "Sims 3 old" if that's what you meant) but the same thing happened. The game didn't respond.

Yes yes, that is the one I renamed !

Haha thank you I was trying to figure out how to change that without going in-game.
 I'll try it and see if it works !
EDIT : Nope, still nothing. As usual there's just a black screen and the cursor loading and I have to use the task manager to quit :/

Yesterday and earlier I waited for about half an hour but it was still the same thing :/
I also kept track of the process' memory usage before aborting it and it keeps going up to over 800 000 K then stopping at some point. I guess that means it's really not responding.

Hello,

I will try reinstalling everything now. It might take some time but I hope it solves the problem :/

Hello,

I uninstalled and reinstalled everything from A to Z, deleted the registry folders and all leftovers but it's still the same problem. I'm so fed up. What should I do?

All of them are cracked.
These are the expansions I have :

- The Sims 3 base game
- The Sims 3 Ambitions
- The Sims 3 Generations
- The Sims 3 Pets
- The Sims 3 Showtime
- The Sims 3 Seasons
- The Sims 3 University Life
- The Sims 3 Island Paradise

All of them are downloaded from Games4theworld except Generations and the base game. Of course, I'm using Games4theworld's Ultimate Fix.

Hello,

I got the base game from Razor1911 and Generations from Reloaded.

Hello,

Yes I did apply the patch, my game is updated to the newest version. Also I'm pretty sure I have the latest version of the ultimate fix.

I re-downloaded the fix and reapplied it but it still won't work :/

Yes, I'm sure I deleted everything before proceeding to reinstall.

Alright, I'll do that. When it's done can I try launching the game before reinstalling all of my EPs ? Just in case it's still not working, don't wanna have to uninstall 7 expansion packs again lol.
Do I have to download Generations from G4TW too?
