The question mark means the computer can't find a operating system. First start up from your system installation disk by inserting the disk and restarting holding down the "C" key. Go to the second page pull down menu, Utilities -> Disk Utility and see if you can repair the drive. If no drive shows up then replace it.

That means that you computer can't find the startup disk, start up holding option to find a drive- if you can't find a drive then that means your HD is fried. In which case you'll need a new one, and if you don't have your data backed up, try using DataRescue.

If you already own DiskWarrior, give that a try, but based on these symptoms I'm not sure if DW to fix this. If the chance is worth 99 dollars to you (plus you'll have it for future use), then give it a try. But usually the flashing question mark means the drive is physically fried, not corrupted.
