The Sims 3 Complete Collection Crashes

Hello ... 
I'm having problem in The Sims 3 Complete Collection.
I have:
Windows 8.1 Pro
RAM: 8.00 GB (7.88 GB usable)
64-bit Operating System, x64-based processor
Processor: Intel(R) Core(TM) i7-3537U CPU @ 2.00GHz   2.50 GHz

After the torrent completed, I installed the base game first, then updated it, cracked it, installed all expansion and stuff packs in order. The game worked fine for like 30 minutes and then it froze and crashed. I started again, it crashed again after like 30 minutes. So I checked for online solution, it said I should try to run it in Windows 7 compatible mode and as an administrator. So I changed the mode of all the expansion packs and base game to Windows 7. And I ran the launcher as an administrator. It worked a little longer, but crashed again. The same thing happened for three times. And the weird part is, when I started it after it's fourth crash, it wouldn't even get past the second loading screen (after selecting my saved game). The loading went halfway through, it would freeze and crash. Then I came to your forums and did the 4GB patch. Deleted the files, as told, in My Documents. I started the game again, it worked for even longer, but crashed again.
Now what the heck should I do?

I have Radeon, AMD and yeah, they are up to date. So ... any other solutions?
