1st issue: The bottom plastic mat that is screwed on for protection is now warped and it has came off my Macbook. Has this happened to anyone else... What can I do to stop this? I would assume its from over heating?? 2nd issue: I recently decided to restore my macbook to factory settings. I take my install disk and it informed me it needs to restart and it will instruct me from there. I restart my computer and I can hear the drive running, but it will not produce anything but a gray screen. Any ideas why, I was thinking that my drive has an issue with it? IF anyone could advise me what I can do to resolve this I would appreciate it.
