Power Mac G5 stuck on light blue screen at startup.

My mac starts normally *until after the Apple/loading screen. After that it stays on a light blue screen.

I have tried a new video card, different RAM. What is the problem? 😢

PowerBook, Other OS

Hello,


Could be many things, we should start with this...


"Try Disk Utility


1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.

2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)

*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*

3. Click the First Aid tab.

4. Select your Mac OS X volume.

5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."

Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.


(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive & clear caches.)


If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.

It booted in Single User Mode. I tried /sbin/fsck -fy , how many times should I have to do it? I did it 15 times, and it always had the same result, "the drive macintosh HD appears to be OK" (or something very close to that...)


After that I did reboot. still doing the same thing.


I have noticed after 5-10 minutes all the fans in the computer go full blast...

If you don't know the model, find the Serial# & use it on one of these sites, but don't post the Serial# here...


Using this serial number locator is way better than Chipmunk, and more secure:

Sorry if you thought I left you hanging on here... I took a break off working on the computer. I got the G5 to boot from a 10.5 leopard disk. I've done everything I can with the disk Utility. Everytime I boot with the disk it says unable to install osx on this system, or something very simular to that. I've come to the conclusion that my hard drive is busted.... Does that sound right?
