    So i was using my Compaq Evo N620c laptop( Windows XP) and i put it on stand by. When i came back, i started the laptop up and it started making a really loud high pitched noise almost like a whistle. I restarted the laptop and it started making the same noise. I went on safe mode and the noise stopped and everything louded perfectly. Than when i went back on my regular account and it started making the noise again. The noise only starts at the blue loading screen for XP. I had this laptop for 2 years and this is the first time this ever happened.

    Will the noise stop if I open up my laptop and use a duster ( high pressure air) and i take out all the dust out of my fan and hard drive?

    Thank You :)

    No way to tell for sure what the noise is coming from with the info provided. Could be a fan, could be a hard drive. I suggest you go ahead and try blowing the dust out with canned air through the cooling vents. Use short bursts instead of a continuous blast. First blow air into the exhaust port first, then into the intake port. Repeat until no more dust appears.

    Try one thing first... mute the sound. Audio hardware can do some strange stuff.
