screen goes dark gray and a restart or shutdown message appears on my screen and computer freezes. what is causing this and is it repeariable?
I'm using a 2007 or 2008 vintage iMac G5.
Generally it will shut down if too hot.
What exactly was the message?
this message appears in a dark gray dropdown window "restart or shutdown use restart button or hold power button for 5 seconds."
It would appears that this message is repeated in several other languages besides english.
computer is frozen and non-responsive to mouse or keyboard input.
If you are correct about the purchase date then it is not a G5 iMac. The iMac sold in 2007 and 2008 were Intel iMacs.

Try repairing the hard drive:
You cannot do this from the same start-up disk. Reboot from your install disk (holding down the C key). Once it opens, select your language, and then go to Disk Utility from the Utilities menu. Select your hard disk as before and click Repair:

Once that is complete reboot again from your usual start-up disk.

Apple's advice on general maintenance:
Alan,
you are correct. I found that it is an earlier than 2007 iMac g5.
Klaus,
not a harddrive issue.
Does that mean you are wrong about the purchased date then?
