I was typing an email when all of the sudden I get a beach ball that won't go away and I can feel my hard drive trying to do something, just working and working over and over. So I do a hard reboot and up on the screen comes a folder icon with a picture of the finder icon inside of it flashing and then a quesion mark flashing, then back to the finder icon, ect. I do another hard reboot and now the gray screen with the apple logo pops up, but that won't go away. After multiple reboots all I get is that Apple screen. Does anyone know what happened or how I can fix this? Did my hard drive just die or is it caught in some sort of strange state that I can get out of?
