Please help - Crashing issues

Hey, i really need help with the sims 3. I have installed all of the
expansions and followed many guides diligently but am still having major
issues. I can run the game, it lets me create sims and choose a
household, but it freezes almost instantly when i go into buy mode, now
when i go to the house screen it can freeze even before i get to the buy
mode screen. This is my story of what iv done already to fix this.

-
Followed instructions carefully on the ultimate fix and installation
guide. Installed all games in correct order (mounted with no problems
also) and applied cracks and fix.
- Next day started to play, everything going fine until i get into house then major crashes.
-
Followed all steps on the crash and freeze guide. Couldnt get anything
to work so decided to reinstall everything, from the zip stage at the
very start. While i was installing i read quite a few forums to see if i
could pick anything up.
- Realised i didnt check my version so downloaded manual patch and replaced the patch with stage 13 of ultimate fix guide.
- Got error disc is not a valid copy, insert master suite disc.
-
Applied last crack of ultimate fix guide to see if that would sort that
problem, and it did, i could get into sims and create and choose a
household
- Everything running fine for few minutes, tried buy mode
and it crashed again. Now it freezes before i even go into buy mode
(again)
- Tried moving "the Sims 3" folder from documents onto desktop (another tip in forums) but same thing happens.

I
guess my next stage would be to try and uninstall pets to see if it
would work without it, but thats one of the expansions i am most looking
forward to playing! Please, please any advice is very welcome, i have
been going round in circles for 3 days now! Im not sure if im making any
nooby mistakes but as far as im aware iv followed all guides very
carefully. This info may help -
