What exactly did you do with virtual memory? Your dxdiag shows plenty of storage set aside for the page file, in truth a lot more than your computer could probably ever use, but if you merely increased this size, that wouldn't affect how Sims 3 runs. The game doesn't respond well to having its data paged, and that wouldn't do anything to overcome the 32-bit limit anyway.
Are you running an existing save or a new one, and did you ever play it with more than the base game active? Since you mentioned not using any expansions, I want to make sure that that's not the issue: removing an expansion from a save that's already been exposed to it can cause anything from terrible performance to an error when trying to load the save in the first place.
Also just to add: I have spent hours trying a million different ways of launching the game. The problem still persists with any variation of expansions activated and with graphics on lowest settings and crap screen resolution. Every other game of mine still working perfectly -- I have no idea what to try next I feel like I've tried everything. I just don't understand how the game has been working perfectly and then suddenly stopped ☹️
