I read a couple places that if I reinstall Snow Leopard that everything else will stay there unless of course, I erase disk first. I just want to make 100% sure this is true before I do it, because I have a LOT of stuff on this disk that is NOT backed up. I have to backup manually and it just so happened that the system only logs up to the apple symbol and then restarts after like 5 minutes. I was just about to do a massive backup just before this happened. Murphy's Law, I guess.
