HP Pavilion dv6 Beeping noise

Hello I didn't know where to really put this so I just put it here due to fitting it the most here.
My problem is that My HP laptop starts beeping from time to time.

It's a short double beep, it's the most annoying beep I heard in my life...
Anyways, it sometimes happens when I play music, but it happens all times generally, basically just a double beep from time to time.When I re-start my laptop it's all OK.

I am using it for facebook and Counter Strike Source and thats really it.I cleaned it today, its perfectly clean 
Maybe its the RAM that maybe isn't in its place or something popped out a little bit ? 
Please help ...
