Screen freeze and game shutdown
TanniB Adding more packs to an existing save shouldn't break it. However, Seasons is the second-most-demanding expansion, after Pets, and your computer's hardware is a bit below the specs needed to run Pets and Seasons together without issues. It's possible that the addition of weather has pushed things past the tipping point.

Set the minimum to 12288 and the max to 16384, and restart your computer.

If you're still getting lag, let me know. Your dxdiag lists three different kinds of Sims 3 errors, two of which are generic enough, at least in this context, to not be helpful. The other type is a crash of the Nvidia graphics driver, and while that's concerning, the fact that it doesn't happen all the time suggests the driver itself might be fine and it's more about the load on the GPU.
