My Macbook has decided to stop starting up correctly. Most of the time, I can't get past the gray startup screen, but if I'm able to type in a password, it just timeouts and eventually turns off. I thought about re-installing OSX, only to find that the Superdrive I never use has somehow sunk into the case. I try to put a CD in, but unless I angle it, it hits some sort of barrier. If I angle a CD into it, I can push firmly to get the CD in, but it sounds like it would do damage. Any ideas? I was able to use a Firewire cable to login for a moment and see my home folder, but now I can't get back in.
