Odd.
I would suggest, if you have it, booting from an external and see what happens. The last time my computer did that, my HDD was destroyed (The S.M.A.R.T. crashed, meaning the drive was useless.) It happened to me in sorta the same way, I was using boot camp and windows crashed, then I force shutdown the same thing happened to me, except there was no apple logo for me.
The other option is sorta like my first idea, if you have the install disk for OS X, try booting from that using an Option Boot. That is how I figured out my S.M.A.R.T. was dead (I ran disk utility from the OS X install screen, and the only thing that came up and reported ”S.M.A.R.T. Error” In big red text, nothing else came up. So I had to swap the HDD myself.
I wish I could be of more help, but without being there it is hard for me to offer help (Mac errors are like that. The same thing can happen to 6 different people, but each one has a different problem and a different fix.)
