System Restore for you http://www.vistax64.com/tutorials/76256-system-restore-undo.html
also could be any solution for you.If you system very often crash and sometimes it require fresh install it would suggest you have any hardware trouble or you have viruses in your backup data and constantly enter them again to fresh installed system.
