Sims 3 Crashes When Opening New World/Traveling [ Edited ]

[bridgct]

  So before yesterday, all I had was the base game. I installed Seasons and Showtime from Origin. I told my best friend about it and she asked if wanted the codes to all expansions and one stuff pack. The stuff pack she gave me is "70's, 80's & 90's Stuff Pack". I started playing immediately after everything finished downloading. Everything was working flawlessly...minus the lag. However, I fixed the lag and everything was fine.

  Today, I got back on, and it just crashed. I reopened it and it crashed again. I always play in windowed mode because when I'm in fullscreen, the lighting is dim and it just gets annoying. I ran the combatibility troubleshooter and tried every singe thing in it. Nothing worked.

  I have Windows 8.1, 64 bit system. Here's my DxDiag:

  And before anyone asks, I've removed all custom content and my mods folder. I also have no store content, just the expansions and the single stuff pack.

  All help would be very much appreciated!
