Ive got a Vaio PCV-2228 and it has worked like a dream for over 3 years. Its only recently that the tower starts to beep. First it was every now and then and now it just constantly emits this high pitch whenever the computer is on! The logo on the front of the tower (under the CD drives) also flashes at the same time! Ive looked everywhere for an answer to get rid of the noise but with no such luck! Any help would be much appretiated!! Chris!
