Loud Noise from HP Pavillion dv9500

\015 Hi there, i have an HP pavalion dv9500 laptop and for about a month a loud whirring/buzz noise kicks in when I booted it up for about 20-30 seconds - it sounds like its coming from the top part of the key board along where the sound comes out. If I pressed the mute button it would go away temporarily,, but over the past weeks it has gradually gotten worse that I cannot have any sound on without the loud noise. I was thinking it could be a fan problem after reading through all your other similiar problems on this site that was noise related but I'm just not sure with it going away with the mute button. I'm not a fabulous person with computers but need some help incase its extremely serious.thanks.\015

Hi, the problem is that when the HP Pavillion is switched on thereis a very loud beeping sound. One long and two short beep together. It renders the unit useless because it does not switch on for sometimes many hours or not at all! It has been doing it for many months and it is just over 2 years old.
