This means that your internal hard drive is not currently bootable. That can happen for a variety of reasons, which are:

  1. The disk has crashed and is no longer usable.
  2. The Mac OS X System Folder has become damaged due to permission problems, a botched software upgrade, or some other software-caused problem.
  3. The hard drive controller on your Mac's logicboard has failed.
Without knowing the model of your Mac, I can only guess what is going on here. To know for sure, you need to locate your original Apple software restore CD/DVD -or- a retail Mac OS X install DVD.
Do the following:
  1. Power on the Mac, insert the bootable CD/DVD.
  2. Hold down the power button until the mac turns off.
  3. Hold down the "C" key on the keyboard and press the power button to turn the unit on.
  4. It will take a while, but your Mac should start booting a copy of Mac OS X off of the CD/DVD.
  5. Once booted into the Installer, locate the menubar at the top of the screen. Click on the "Apple" icon (top left of screen) and click "About this Mac". Click the "More Info..." button.
  6. You should now see the Apple System Profiler.
  7. On the left panel, locate "ATA" or "Serial-ATA". You should have one of them contained within your Mac. When you click on the correct one, you should see the list of hard drive controllers (two), one with your CD/DVD rom listed, and the other with your hard drive listed underneath. If you don't see two controllers, one or both of your hard drive controllers have failed and you need to send the Mac to Apple for hardware repair.
  8. If you DO see your hard drive listed, then you hardware is at least working. That rules out a failed hard drive controller and mostly likely your hard drive is physically intact. The software on it might still be wrecked, but the hardware appears to work.
  9. Close "System Profiler" and get back to the MacOS X Installer. Click on the "Tools" or "Utilities" on the top of the menu bar. Locate "Disk Utility" and launch it.
  10. Within Disk Utility, locate your hard drive on the left side of the screen, click on it once to highlight it and then click the button "Verify Disk". This will do an exhaustive search against your drive to see if there are any problems with the Mac OS X installation. If there is still a copy of Mac OS X left to salvage, this will tell what the problem is.
  11. If "Verify Disk" finds an instance of Mac OS X with problems, you can try running "Repair Disk" and then "Repair Disk Permissions" to clean up any problems with the copy of Mac OS X. Keep in mind, when you have filesystem problems, sometimes fixing the problems can make permanent changes to your filesystem that have unintended consequences.
At this point, if your hardware is intact and you have a filesystem problem, the safest thing to do is to go find a firewire drive big enough to install a copy of Mac OS X on it (anything larger than 10GB should be fine), install Mac OS X to the firewire drive and then try to mount your internal hard drive while running from Mac OS X on the firewire drive. This assumes that you have files on the internal drive that you don't want to lose. If this is not the case, you can safely reinstall Mac OS X on your internal drive and start over again.

MacBook Air ? mark flashing

Short answer -> If the flashing icon is a question mark on a folder, it means that your MacBook cannot find a bootable drive.

Longer answer-> If you have an Apple store near you, they can diagnose it more thoroughly. If you have been doing periodic backups to a Time Capsule or other device, take that with you.

G5 problemSomething downloaded and took up all the memory now all I get is a gray screen and flashing ? with finder folder

The flashing ? means that the computer is unable to find an OS.
This is caused by either the start-up folder being damaged, or, that the hard drive has failed. From what you say, the hard drive will need to be replaced.

Flashing question mark

Sounds like your computer needs to be looked at by a tech. Usually the flashing question mark means it doesn't recognize the hard drive or is unable to locate an operating system.

Hi Joe. It means that the start-up drive has some corruption of some sort. I've posted previously what to do in such situations so just search for flashing question mark and there's a walkthrough of possible fixes.

My Mac Book will only go as far as a blue screen with a folder flashing a question mark. What does this mean?(also there's a ticking sound near the DVD drive when i first start up)

The DVD ticking sound is normal and happens every time you power on. The blue screen of death is not normal. The flashing question mark means corrupt start up file. Re-install the operating system or insert disc 1 of your gray install disc and go into disk utilities and select repair permissions. Then select repair hard drive.

My Powerbook G4 turns on light, fan, chime but no video.

Your hard drive has lost a file needed to start up the machine. The folder with the question mark means it cannot find a useable Operating system. I hope you backed up your files you needed becuase the only real way to recover the machine is to reinstall the OS from the install disk. You must format the Hard Drive from the format option on the install disk and reinstall the OS.

When I start my macbook a blue screen appears with a folder with a ? mark in it flashing

That message means that it can't find the start up folder and or your hard drive has crashed.

If you insert your OS disk or a copy of Disk Warrior you can boot to the cd / dvd by holding down the "C" key and then powering up the Macbook.

Let me know if you have that OS cd and then we'll go from there.

Screen goes white, flashing a folder with a question mark

The flashing folder means that the computer can't find the boot system on the hard drive. If your girlfriend's step-dad has removed some parts of the OS, then the system will not start giving the 'flashing folder' result. You will need to re-install the OS from the system disk.
Insert the disk into the computer and it will boot from that and take you through the install procedure.
