I have a Macbook that I bought in July 2010 from the online Apple store. Until now it has been relatively problem free. It now sounds like there is a chainsaw inside of it, the hard drive is making a strange metal noise and the plastic housing on the bottom has started to bubble and warp near the fan and hard drive area? I'm overseas and having trouble sending it in for repair but in the meantime does any one have an idea about whats going on?
