sony vaio running windows 7 beeps twice

now i read other threads but no help, i posted earlier today on another thread and how convenient i have another problem, i have a sony vaio L series touch screen that all of a sudden beeps twice on different occasions, when i have my projector to it (projector is not on all the time) i may be watching netflix online and then beep beep everything minimizes. doesnt happen all the time when it beeps but its just annoying. any suggestions?

Is it new ? Do you have a warranty ?

Yes it's new but from out of town.

If no one here can help, I`d call Sony support.

if the beep is coming from inside of your computer and no from the speakers thats mean: hardware not fuction correct or hardware not fuction at all !!

It's coming from the speakers.

Sony support been threw 5 people, and act lazy like they don't wanna help

if is new you have to go and take new!!!! even if is software problem if you touch it you loosing the warranty!!
