1.Insert the Mac OS X Install CD or DVD.
2.Restart Mac, immediately after the bong, hold down the C key until the Apple logo appears.
3.When the Installer reaches the INTRODUCTION phase, click on Utilities at the top of the screen, and drop down to Disk Utility.
4.Click the First Aid tab.
5.Highlight the boot hard drive volume or partition.
6.Click Repair Disk.
7.Repeat steps 5 and 6 until the scan comes up all clean and good (and run it one more time).
8.Quit Disk Utility and the OS Installer and reboot.
9.Firewire Target Disk Mode is another option we should know about.
Cheers.

Yes, that is very weird.
First thing I would try is tossing the preferences. Find the file "com.apple.DiskUtility.plist" in your home directory "Library/Preferences" folder.
If that does not work: Do you have more than one volume on your computer? Does this happen with every volume?
You could also try to boot from the OS CD (or the restore CD that came with your computer). Disk Utility is available under the "installer" menu. Don't run the installer, just look for the "disk utility". If that also does not work, then there may be something wrong with logic board.

Use Tech Tool or Disk Warrior to try and repair the file, failing that use Install disk (OS x) and go to install, select options, select install and archive and that will give you a new system without losing any data or apps. You may have to re-install some 3rd party apps/ passwords, but all in all an easier fix than erase and install. It may be worthwhile if you do get it up and running to back up all your data, as the HD may be on it's way out.
Testimonial: "Thanks for the help! It is greatly appreciated! Will do as you suggested! Thanks again!"

If you see a flashing question mark when you start your Mac, it's probably because it can't find the system software it needs to start up. Usually, all you have to do to get your Mac back up and running is remind it where its software is.
If your computer starts up normally after a brief delay, you probably just need to reselect the startup disk in Startup Disk preferences. It's normal to see the flashing question mark when a startup disk has not been selected. In most cases, reselecting the startup disk is all that is required to resolve the issue.
Sometimes, your computer may not start beyond the flashing question mark.
Tip: If your computer has a gray screen (with no flashing question mark) startup issue, see Mac OS X: Gray screen appears during startup.
Check the mouse and keyboard
This issue might occur if a mouse or trackpad button is pressed during startup. Make sure the button isn't pressed.
If the issue persists, shut down your Mac with its power button, disconnect any external mouse and keyboard, then turn on your Mac with its power button. If the flashing question mark issue persists, reconnect the keyboard and mouse.
Additional steps
If your Mac still starts to a flashing question mark, follow the steps below. If any step resolves the issue, you don't need to continue to the next one.
MacBook Air note: On a MacBook Air, there are two options for starting up from Mac OS X media: Either connect a MacBook Air SuperDrive to the MacBook Air via the USB port and restart the computer, holding down the C key during startup, or use Remote Install Mac OS X to startup from a system software DVD that's located on a partner computer. Once started up from Mac OS X media, skip to step 3.

Important: If Disk Utility finds issues it cannot repair, you may need to back up as much of your data as possible (or use Time Machine to back up to a different disk), then erase the disk and reinstall Mac OS X. You should back up important files and data before erasing a drive. Erasing deletes everything on the hard disk (including things on your desktop). Also, you can install Mac OS X onto an external disk, start from the external disk, and use Migration Assistant to transfer items from your usual internal Mac OS X startup disk to the external disk, then erase the internal disk and reinstall Mac OS X.
