Today, out of no where, the right side of my laptop (if facing to type) started to make a funny noise. I turned it off and turned it back on. The noise went down a lil but it's still there. Sounds like the hard drive. It's spinning, but not like usual. This is a first gen intel 15inch macbook pro
It's not really loud but noticeable. It's also not the type of spin when it's under heavy duty pressure, it's more of an idle calm spin but with a slight glitch to it.
should i be worried?
edit: crap the noise got a lil louder, it's like a really fast tapping noise.
