    try reinstalling os x. if that doesn't work then my next guess would be hard drive failure. the same thing happened to a roommate of mine where his laptop froze and would not boot into windows. instead of the usual windows splash screen he would get an error message saying something like no os found. turns out it was a dead hard drive.

    I have a colleague with an iMac (1 1/2 yr old) that is doing the same thing. Also, it won't boot from a System DVD, or other CD/DVD. I can get into single user mode but fsck gives 'Invalid node structure' and 'Volume check failed' errors.
