|"accessories and utilities is unchecked from windows components"|
You need a Windows XP CD to restore any of the Windows accessories and utilities items. If you don't have one, try and borrow one from a friend, but it must be for the same XP version as yours.
However, I don't see what that has to do with your speakers not working. To fix that, you may need to re-install the sound driver from your PC maker's website.
