Problems with loading sunset valley

@MandyLovesPink35  I understand you don't want to play without mods.  However, I really need you to test without them before you do anything else.  Otherwise, I won't know what suggestions to make, and I could end up wasting both of our time chasing down something that isn't a real problem.

Please creaate another new Sims 3 folder, add absolutely nothing to it, and let me know whether you can load a new save in Sunset Valley.  If it doesn't load, please run a dxdiag and attach it to a post, as explained in the article on dxdiags that I linked earlier in this thread.

If you won't do these two steps, then I won't be able to help you.
