Hi i really need help... I have been hearing random noises and voices coming out from my Mac laptop. I brought it last year and it has Mac OS X 10.5.8... It sounded like it was from a video.. oh and a popping noises when someone gives you a message from facebook...... It even sounded like a loud purr at one stage. Anyway... when it happened i hid all my applications that was open and... nothing was there. The noises sometimes goes on for like a few seconds. I dont now what the problem is and i dont now where the source is coming from. I went over to the Mac shop and he said that he needs the source so they can eliminate it... He also said that i could be that voice over application... but it wasnt even close to that noise... >.<"
