A fresh install is definitely the way to go to keep issues and bugs at bay but not recommended if you're looking to keep your data. If you're feeling brave enough to do a fresh install just make sure you back up your data first and perhaps make a list of programs you'd like to reinstall. /u/Autumnal 's advice is sharp though, installing a fresh copy can avoid issues down the line.
