some mobos (like my moms compaq's mobo) will speed the cpu fan up when the cpu gets hotter, causng a sound kind of like buzzing. It does it while booting, and every now and then when you are running a lot of programs.
although, my chipset fan makes a buzzing noise from rubbing against something, or the bearing worn out, or somethiing, i dont know what, but it goes way after a litle while never to return until i leave the compy off for a while. its all right, though, i am getting a new mobo very soon :D
