Well the first thing has been happening for a while now but whenever I move my macbook pro fast, like picking it up or something, it makes a clicking noise. Second, I turned my computer on this morning and while the screen was still black it made like a 2 second loud noise and then the screen went to the white screen with the gray apple logo like on a normal start-up but it had like a loading bar underneath the apple logo and then shut off and then turned back on. Has this happened to anyone before? Does anyone know what this is? Thanks
