Hmm, both of these things say that my hard drive is in good health

Thanks, that's a nifty program. It didn't seem to fix my Sims problems, but I'm definitely going to keep it for other stuff.

I patch from the launcher so I think everything is all patched up. And I'm posting here because the official Sims 3 forums kind of suck. I did have some mods and pirated stuff before, including awesomemod, but I deleted them when I reinstalled so I could see if I could run TS3 if it was completely vanilla. As for how long I've had this problem, it's been at least two years. One thing I probably should have mentioned; I CAN play my game if I leave it frozen like that for about 3 hours. Then it just pops back to normal and plays well, without freezing.
