No, because the binaural beats are optional, and you already have experience with altered states. But if you want to have the fun of the binaurals, you'll have to either see about getting the pc fixed.



-----------------The long version of this answer is that binaural beats get your brainwave synchronized to altered state (pre-trance and trance states) so that you learn how they feel, and they help you achieve the state with less 'disbelief'. But since you already are a medium you are already trained in this, so you don't really need them.
