The computer turns ON but does not boot  a system , all i have the GREY screen   with NO  apple logo  and NO  turning weel .after about 40 sec the blinking interogation come up.

i reset the pram by switching  off the power ,and turnit it on againg ->hold command/option/p/r  until shimed twice  ->restet -nvram ->set-defaults ->reset-all  NO LUCK

i tried to connect it to the another mac (imac g5 17 ) via firewire by holding t key of the sick imac but the  hard drive icon  does not show up in the other working imac.i do not have the original retail dvd (black one) to try installing or even repairing the disk via disk utility ,i ve tried grey  disk 10.4.6 which i had

    If the seller proclaimed that he/she was selling a working computer, strongly suggest that you get your money back.  You don't know what could be wrong nor the real condition of the computer.


    Macs are not suppose to be sold w/o the system DVDs that originally came w/the computer. You will need to obtain them from the seller.  System DVDs are machine specific and cannot be used from one computer to another.  You also need them for troubleshooting as one of them comes w/the Hardware Test.


    You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.


    If you're not in the US, you may need to go through the regional Apple Store that serves your location to find the contact number. Here's a list of links to all of those - http://store.apple.com/Catalog/US/Images/intlstoreroutingpage.html  Another resource:  International Support Phone #s.

    1) Try a safe boot.

        Shutdown your machine.  Hold down the shift key.  Poweron.  Wait awhile Wait awhile while you harddrive

          is being checked.



    2) You need to get into single use mode for steps one and two that are listed below.

        This page will tell you how to get into single user mode.



       Basically, you hold down the command + s key then  powering on your machine. The command key

       has a little apple symbol on the lower left. It is between the alt/option key and the space bar.

       On a PC keyboard, it will be the windows key, I think.
