Hey all... my laptop started making a funny 'crackling' noise a few months ago. At the time I discovered ants in it. After a few weeks the noise stopped. Today it started again, and a bit louder. It sounds like a clatter or clack, and comes from the left side of the computer. I was able to feel it where the palm of my hand rests when typing as well. I'm making emergency CDs of some stuff, but has anybody got any ideas on what might be wrong?
