Hi there I spilt some Juice on the port side of my macbook, I opened her up since I had extra parts but have come to a problem. From what I could tell it looked like it was just my Network card that had gotten fried. I swapped out the part and things have been running smooth until up to two weeks ago. It will continually disconnect from any wireless connection and cause whatever is running i.e. iTunes to lock up and glitch. This happens out of sync therefore I can't tell when it's going to happen next...
