Mac G4 Blue screen only after restart

After a 'security update' I restarted my Mac G4 computer. When it loads a gray screen with the apple icon appears followed by a blue screen. I do not know why it doesn't let me go any further. I have tried diagnostic repair in the installation disk but that didn' t solve the problem. If you can help me out it would be greatly appreciated. Thanks!

How do i shut mac off then put start up disk in ?


Simple. Load the Apple System start-up disc first while the computer is running. You should see its icon on on the screen. Then select restart from the Apple Menu on the top left of the screen. Hold down the C key as it reboots. You will now boot into the start-up disc. This method also applies to Disc Warrior and other tools. Alternately, with the computer already running, insert the Apple System start-up disc then go to System Preferences also under the Apple menu, Under the start-up disc icon, select your apple system icon and restart.
Third alternative. With the computer running insert Apple System start-up disc. Restart the computer. Before the chime, press and hold the option key, left-hand bottom side of the keyboard to the left of the Apple (Command) key. You will see your system HD icon and the screen as well as your Apple System disc. Click on the System Disc and that will boot the machine.

My powerbook g4 is not starting. it opens the gray screen and just says i need to restart the computer. i tried restarting it and removing the battery a bunch of time and nothing is happening. HELP!!!


I am going to have you take your Mac into Safe Mode to see if we can't remove a possible folder(s) that may be affecting your Mac's start up function.

Try these steps:


-SAFE BOOT MODE-
• Reboot your Mac
• Upon restarting your Mac, press the Shift key.
• Hold the Shift key until you see a White Screen with Gray Apple icon and eventually a spinning gear.
• When you see the Spinning gear, release the Shift key.
• Allow the Powerbook G4 to continue booting up. Also this may take a little while
(NOTE: this may take anywhere from 5 to 15 minutes to load to the Safe mode screen depending on the performance of your Mac, but if it exceeds this time, shutdown your Powerbook G4 and try just once more. It may have just frozen up the first time around for you.)

• You are going to enter the Safe Mode (which looks like your main desktop environment - the only difference is certain start up items are disabled.)

• Once within the Desktop in Safe Mode
• From the Finder Menu, click Go> Go to Folder
• Type in this line: /System/Library/StartupItems
• This path, is going to take you to the System Library folder which has all of your Mac OS X Startupitems.
• Remove all of those folders to the Trash.

*Reboot your Mac normally and see if you can access your normal User desktop environment.

At times this procedure does help for gray screen issues so give this a try and let me know if this helps.

Thanks!

HELP!!! I am trying to start my Powerbook G4 but as soon as it turns on I just get a grey screen that says that i need to restart my computer. i tried restarting it like 10 times. what else can i do?


Also, check your RAM bay port to see if one of the RAM boards came dislodged and is not inserted correctly. Could also be one of your RAM boards is not compatible or one of the RAM boards is defective.

Try resetting your pram:
  1. Shut down the computer.
  2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
  3. Turn on the computer.
  4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
  5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
  6. Release the keys.

Stuck on the restart your computer screen.


You may have installed something in the startup items folder that your mac isn't liking. 
When you turn the iBook on, press the shift key as soon as you hear the startup tone. hold it down until you see the gray apple screen. This will get you into safe mode, hopefully then you'll be able to fix whatever you did from there. If you are still at a loss, get in touch.
