update

I tried to apply a firmware update on a MacBook Pro 2.4ghz (2008), and after rebooting, the fans kicked up to maximum, the screen lit up, and then it immediately died. Now when I try to boot, it does the same thing: the fans crank to max, the screen lights up, and then it dies after about 2 seconds.

Resetting the power manager does nothing. It doesn't stay up long enough to choose another boot drive or boot from CD. I have no idea what else to try. Help?
