Q: Power Mac G5 won't finish booting up

My G5 no longer fully boots up.

 

It gets as far as a gray screen with vertical stripes and greyed out text. Here's what I see.

 

Zapping the PRAM makes no difference.

 

Moving the keyboard and mouse from a USB hub (and unplugging that) makes no difference.

 

The eject button does not open the DVD drawer.

 

Resetting the monitor cable makes no difference.

 

Is this a motherboard issue or something else?

    Hardware issues are very tedious to troubleshoot -

     

    you have replaced the monitor cable (? or did you simply re-SEAT teh connections?).

     

    Next, I would try a different monitor (the goal at this point is to 'eliminate' the monitor as the cause).

     

    You have posted in the PowerBOOK forum, so please verify your Mac model - Power MAC is a desktop.

     

    If Power MAC, cracking open the case and jiggling the video connector cable (re-SEAT - unplug then replug) may help. You also may find it is a dirty bird on the inside of the case. Gentle vacuum + canned air.

     

    Other folks more experienced with the seeing the image (this IS a PHOTO, not a screenshot, right?) may have more to add.

    Does it do any better or even different holding Shift key at bootup?

    Here is a little more info on safe boot which bdaqua suggested.

     

    Try a safe boot.

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

         is being checked.
