I can play the game fine for about 30 minutes and then it freezes for a couple seconds and crashes. Lately it has been getting worse. I checked the DEP and it was fine. I do have some CC installed, I tried to delete some of the suspicious ones, but it didn't help any. Now when I try to uninstall some CC it pulls up the uninstalling screen and then THAT crashes. I have Generations and Pets installed as well. I also have a glitch where the Sims will randomly not be able to move anywhere. I have to go into buy mode and move them, it only happens with certain Sims and it happens pretty frequently.
I had this problem too, and I did the same as you (deleting the custom content, etc), and it still crashed.
So far, the only way I've been able to run Sims 3 without it crashing (on Windows 8, that is) is to run it in compatibility mode for Windows XP (I chose Windows XP instead of Windows 7 because 7 makes the graphics look poopy on my computer).
To run it in compatibility mode, just right-click on Sims 3, go to Properties, then go into the Compatibility tab and choose "Run this program in compatibility mode for... ".
As for the sims randomly freezing, I didn't have that problem so I can't help you on that one. Maybe running Sims 3 in compatibility mode will get rid of that?
Anyway, I hope I was able to help you out. :3
