Sauron

ok i'm confused about sauron. Even though he put most of his power into the one ring he did not put all of it. SO why did it kill him? He and his army still seemed pretty powerful while the ring was in the hands of his enemies. And nothing says that they went into his fortress and killed him <img src=http://www.ezboard.com/intl/aenglish/images/emoticons/ohwell.gif ALT=":\"> hmmm... also what happened to his spirit??? ne ideas?
