What is this horrible clacking noise?
I have a two-year-old MacBook Core 2 Duo, which has begun occasionally making a loud noise over the last month: sometimes whirring, sometimes clacking, sometimes clicking.
The noise seems unrelated to which / how many programs are running--sometimes it begins when I open up my computer with no programs open and continues until I shut the lid, whereas other times it will start seemingly randomly as I'm working in Word or browsing online. I don't have anything in the CD drive.
I would say I hear some kind of unusual noise of varying loudness coming from my laptop about 25% of the time I'm using it, now. At its worst, it can be heard even when I'm playing music over my laptop speakers at full volume. It sounds like it's coming out of the back of the computer, and I'm pretty sure it's not the hard drive.
(I'm not sure whether or not it's relevant, but occasionally my laptop fails to pick up any wireless signal--even in my apartment, where I know there to be about 15 networks in range.)
So, here's my question: What could make this kind of noise? Why might it be so intermittent? Is there anything I can do to fix it?
