Sims 3 pets issues

No custom mods or content.

And now the game is doing it outside of using the Pets (which I've just learned now, since I'm not trying to get Pets for my Sims anymore), it does it when my Sim goes into town too and occasionally at home. When I ctrl+alt+delete out of the game, sometimes I can go back in and I hear that the game is running normally again, but the screen is totally black. Here's the DxDiag if that helps.
