The thing is slow and needs some cleansing, help me remember what I should do for a checklist to make sure I don't fuck anything up:

List:

-Windows XP cd with serial #
-Backup documents, music, movies
-No need to backup games, don't even play them anymore
-Going to buy HEM so no need for PT and PAHUD backup
-Updated drivers on external HD for easy updates

Anything else I'm missing?
