So I am pretty sure that my laptop has something wrong with it... When it gets turned on, it makes this humming sound like, similar to it reading a CD, even when there's no CD in there, and the noise is coming from the opposite side. It just started this yesterday I believe, and sounded kind of like a car switching gears, it would hum and get higher pitched, then stop and hum and start to get higher pitched again...

I'd appreciate any help if anyone knows about computers
