PowerMac G5 & Display starts but after the grey Apple logo screen dies

When I turn on my PowerMac G5 it turns on OK along with the LCD display. But once the Apple logo and the spinning gear shows up (by the way the gear gets all pixelated and turns blue) the LCD display suddenly goes black as if it goes to sleep. The PowerMac is still running though but it's not responsive. I even tried opening the DVD drive with the keyboard and nothing happens. I took someone's advice of rebooting in Safe Mode and everything works OK for now. When I try rebooting in normal mode the problem persists.
What could be the problem? Is this a hardware issue? I even tried with another display and same thing happens.
Sad thing is my 3 yr. Apple Care expired a few months ago, never ever used it.

Second time I've heard of display problems and 10.5.5., but it might be coincidental. For the other poster starting up in safe mode also helped but didn't cure his problem. Maybe taking out and reinstalling the video card would bring your mac back to its senses again.

I was looking for some display preference to be trashed but there were so darn many of them I couldn't figure out what the right one might be. In case I missed it, have you tried resetting your PRAM?

Boot with the Snow Leopard install disc and reinstall the software.

Why is my G5 is stopping on the grey+apple logo screen when starting up?

My G5 is stopping on the grey+apple logo screen when starting up and fans run faster than usual after a couple minutes. I have read many of the posts related here, but it seems none are exactly what I am experiencing. Here is what I have done:
+Disconnected all peripheral devices (except for keyboard and mouse).
+Unplugged power cord and plugged back in.
+Unplugged ethernet cable.
+Removed added memory.
+Reset the SMU button on the logic board.
+Reset the PRAM by pressing Command-Option-P-R keys. It makes its second start up chime but I still get the grey screen.
+After opening the disc door with a paper clip, started up while pressing "C" with Hardware Test CD which found no problems.
+However, also started up with Systemworks disc and ran Disc Doctor, but I get an "unexpected problem, Error found: disk error" while "Checking Directories: Catalog Structure". When trying to run Speed Disc, my hard drive doesn't even show up in the window to select it. Nor does it show up in Disk Viewer.
I have not tried to start up from the original Mac Startup or installation disc that came with the computer. I am not at my G5 right now (having to use the internet at work). If I start up with that disc, will I loose any work (if I haven't already) that I haven't backed up?
Also, the G5 manual suggests replacing the lithium battery inside the tower if I am having problems starting up. I have not read to do this anywhere else except in the manual. It mentions having problems with the date and time which I haven't so I doubt it's the battery.
Any suggestions?
Thanks,
Tony
G5 Power Mac Mac OS X (10.0.x)

First and foremost you should never use Norton Utilities Disk Doctor or Speed Disk. They will corrupt your hard drive. NUM is not compatible with modern Macs and is no longer supported by Symantec. I highly recommend you uninstall it. You will find instructions here.
You should do the following:
Boot from your Tiger DVD. After the installer loads select your language and click on the Continue button, then select Disk Utility from the Utilities menu . After DU loads select your OS X volume from the list on the left, click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now shutdown the computer for a couple of minutes and then restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (3.0.3 for Tiger) and/or TechTool Pro (4.1.1 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
If this does not fix the problem, then it's possible your system files have been damaged in which case you may need to reinstall OS X. You can do this by an Archive and Install which does not require erasing the hard drive. However, the hard drive must be verified as OK per the preceeding intructions.

PBT wont start up passed the grey apple logo, I get a very weird

PBT 400mhz wont start up passed the grey apple logo, I get a very weird symbol after 5 minutes of the logo. I get the "NOT" symbol. A circle with the line through it, then it just locks up forever.
Booting from a Tiger DVD gets a boot but sees no Hard drive or rather it says "an install error occured". (i was hoping an Tiger upgrade would fix the problem..)
Brand new hard drive with 10.3.x was very recently installed w/no problems. Any ideas?

Oh I picked the ATARI 2800 format! Ooops!
Of course I picked the Mac OS Extended...
Well, you might be surprised to know how many people don't. One has to ask.
There was NO SMART status as I believ its not on 2.5" drives (?).
Not true. Some have SMART built in; others don't. Lately they all do. Jaguar may not support SMART (I don't recall), but Panther and Tiger do if your drive is equipped with it.
Installer disks are fine I use them to install on used macs to sell all the time...
...which, to all appearances, makes you a flagrant, repeat violator of Apple's licensing agreement and of the laws against software piracy. Probably not a good idea to advertise this here in Apple's house.
As for your LB error message in AHT, I'd hazard a guess (because your hard drive no longer appears) that it might have something to do with the ATA controller on the LB. Perhaps the controller was gagging intermittently for a while before its final complete collapse, which may now have occurred. Replacing the board is the remedy.

The Macbook Pro will not start past the grey Apple logo screen? Any help will be most welcome?

The Macbook Pro 13, late 2009 will not start past the grey Apple Logo screen? Any help will be most welcome? Thanks

Have you tried booting with the install disc that came with your computer?
Find it and then run Disk Utility to verify your hard drive. If errors are found, try to repair the disk.
It sounds as if the hard drive might be failing.

G5 dual 2.7GHz refuses to get past the grey apple logo screen no matter what I do!

Hoping that someone might be able to help, as I think I have tried pretty much everything and I’m running out of ideas now!
It’s a G5 dual 2.7GHz that refuses to get past the grey apple logo screen no matter what I do!
everything passes the extended apple hardware test (2.5)
3GB of RAM (2x1GB brand new from crucial)
won’t start from a original OS 10.58 disk
passes disk utility when connected to another mac via FW target mode
nothing other than keyboard/monitor attached
all of this done; http://support.apple.com/kb/TS2570
tried alternative HDD’s without any joy
won’t safe boot
stays at the grey apple logo screen and the fans then start revving up excessively
Any other suggestions or advice very gratefully received!

Seems strange that it's trying to invoke "AppleIntelCPUPowerManagement" on a G5, but maybe it's all inclusive???
Though it exists on my Universal 10.5.8 Install, it does NOT appear to be a loaded extension....
/System/Library/Extensions/AppleIntelCPUPowerManagement.kext
BD, is that showing up in your PM's extensions folder? I wouldn't expect to see it loaded in a PM, but I wonder why the installer loads it unless the 10.5 installer loads a system that could boot an Intel, too, when it installs on a PM. (I read somewhere this weekend that an Intel will actually boot from an APM formatted disc as well as a GUID formatted disc) Curious.
I recall seeing yesterday or Saturday on one of the discussion threads someone having that extension show up in a verbose boot on a PM that was having problems booting into Leo. I think I advised trashing the kernel caches and touching Extensions in that one, but it is puzzling that it shows up here as well.

My powerbook won't load past the grey apple logo screen

I had been away on business for a few weeks and yesterday I decided to run the latest updates for my powerbook. In the middle of it the computer froze for what I think is the first time since I bought it 2 years ago. I ended up having to shut the computer down with the power button. When I turned it on it wouldn't and still won't advance past the grey apple logo screen with the progress indicator. It just sits there for hours on end if I let it.
So far I've tried the following, all to no avail.
Booting in safe mode I get the same result.
Zapping the Ram
Resetting the PMU
Reinstalling OS X, during which the computer either randomly shuts down or goes to sleep and then shuts down and requires me to reset the PMU in order to start again.
Running the hardware diagnosis. I did this once and it froze during the logic board test, 1 minute 6 seconds in to it.
Anyone have any ideas that don't involve spending 900 dollars on a logic board? Thanks a lot for any help.

joeuu, thanks for the reply. i checked the airport and the ram and both seem to be seated properly.
i ran the quick hardware diagnosis and it came back showing everything was fine.
when i ran the extended one i got more progress than i did the first time. it got to the RAM diagnosis (about 6:45 seconds in) and then froze - i let it sit like this for an hour and a half to make sure it was actually frozen.
i also tried to run the disc utility from the installation disc and it just sits there with the progress wheel spinning, but nothing else is going on.

Trying to install the snow leopard update, but get a grey apple logo screen

I cleaned my imac out, and now want to install snow leopard (NOT LION), I already installed Leopard, and the machine works, but when I try to install snow leopard, it runs(installs) and after a while it gives a message that it will finish installation after restarting , but then it just gives a grey screen with a apple logo, and nothing happens, cant use the keyboard also, its been standing on this screen overnight(so Im not impatient ) I then switch it off at the power button and restart it keeping eject in, it ejects the disk and then starts with the normal leopard os, I can open/close/use programs/aperture/itunes etc. and the machine seems just fine, its just that it will not work(finish installation of) after I try to install snow leopard.
I have installed snow leopard on a few occasions before like this on this imac and my MBPro, and had never had this problem.
I have reinstalled leopard and tried reinstalling snow leopard a couple of times in the last day, and there seems to be no problem with the machine, aka it works fine, it will just not load SLeopard,
I dont have a time machine backup, as I dont use it, all my data are on a external disk, (which I did a few minutes before erasing my imac )
I have erased disks and reinstalled it, installed it over the existing leopard, used disk utility , verified disk, verified permissions , but no luck
please help !!
(it seems that my spell checker doesnt work in this box/forum )

Do tell us HOW it was fixed. It helps others.

Please help me!! My Power Mac G5 is stuck at the grey apple logo screen and nothing is working!

My computer froze a few weeks ago and I got a grey screen that told me I needed to restart the computer. When I restarted, the computer froze on the grey screen with the apple logo. No pin wheel. Nothing. Eventually the fan begins running at warp speed. I've scoured this discussion board for a solution and I've read every possible thing I can find on the Internet regarding this issue. Nothing is helping. I've tried reseating memory, resetting PRAM, I replaced the PRAM battery, all the standard stuff on the message boards. I can't run a disk, i cant boot from a disk holding down c, but I can hold down the option key to open the hardware test, I've done the extended and short test and passed both.
When I hold the shift+command+v it tells me-
com.apple.driver.appleintelcpupowermanagement isn't a valid Mach-o (magic is cefaedfe)
Error mapping module file com.apple.driver.appleintelcpupowermanagement
Can't map com.apple.driver.appleintelcpupowermanagement in preparation for loading
Can't determine dependencies " "
Can't alloc class " " blah blah blah
I'm pretty sure this is some sort of kernel panic. This computer has been pretty much trouble free in the 8 years I've owned it. I had recently upgraded iLife to iLife 07 before the trouble happened.
I've also been able to get it to boot once or twice since then. I get a message that says" the computer was shut down blah blah do you want to send a report to apple?" I'm able to do some basic stuff like back up some pictures onto my external hard drive and then it will freeze again and the fan will come on. While I had access to the desktop I checked the disk repair permissions and they were all messed up. I tried repairing permissions but I don't think it worked. Also the time and date was messed up which made me think it was a battery thing. Lately I haven't been able to boot at all past the apple screen. I don't have much money but I have to get this fixed!
Some specs--
Power mac g5
CPU @1702037.8 ghz
Boot rom version 5.2.4f1
Memory 8 gb, 400mhz
Pmu/fcu versions:127/6.0.1 f0
Running OSX 10.5.6
Just to be clear this is the power pc from around early 2005, not the intel based g5, not the water cooled one, and not a Mac Pro!
Please help me!!

HI, have you blown the dust out lately?
Does it boot better/further if allowed to cool?
If you're sure the RAM is good, try the Hair Dryer trick...

Major Problem! Booting gets stuck on the grey Apple Logo Screen

HI All,
My iMac wont startup. It gets to the screen with the apple logo on it with the small dial spinning and thats it .... I left it for a bout 10 - 15 mins and thats as far as its got!
I'm running 10.5 with the 300 GB HD partitioned into 2 one for Mac and the other running windows through boot camp. I booted from 10.5 disk... went to Disk utility and repair It only shows the the one disk 300GB usually it wold show 3 the 300GB and the 2 partitions as a sub of this.
Another thing I'v noticed is that looking in the start up disk nothing appears in there apart from the CD.
SIf I just wanded to reinstall the OS doesn't even look as if thats a possibility.
OK... So I tried the same thing but booting from and older operating system disk 10.4. I disk repair the 2 partitions are there so I run the disk repair while repaiing it come up with 'Incorrect number of threads recorded'... continues throught the other things like checking multi linked files etc. gets to the end then repeats the reparing volume. It automatically did the for 3 times now and its finally finished says
Error: The underlying task reported failure on exit
1 HFS Volume Checked
1 volume could not be repaired because of an error
Repair attempted on 1 Volume
1 volume could no be repaired
.. looks obvious to me that there is a problem with the HD that it cant seem to fix.
Does anybody have any ideas what I may be able to do to try and fix this problem or does it sound like the HD is dead?
Thnaks
Wayne

Ive just restarted held down option and managed to boot in windows so I know that this part of the disk partition is running good.
However I tried the Install & Archive option on the Mac partition from the 10.4 System CD and it will only get as far as Varifying destination disk the progress bar move only a couple of mm and thats it.

PowerPC Mac Mini gets stuck at grey apple logo screen, wont start

I have a bit of a problem and would appreciate some help, im not especially good at this stuff.
My Powerpc Mac Mini froze up recently, having left it on for a few days without shutting down/resetting. I impatiently turned it off with the power button at the back. When I turned it on again, it only got as far as the grey apple logo screen, it now refuses to go past this screen despite numerous power resets, and unplugging at the power.
I have reset the PMU and the PRAM as suggested by the troubleshooting, to no avail - the PRAM did work as it changed the resolution of the apple logo, but still got stuck at the grey startup screen. Its out of warranty so I have to pay for technical support. Can anyone help?
Message was edited by: misternuge

If you have the original install disk that came with your mini, the first thing to do is to insert that, and then boot the system holding the C key down. This should force it to boot from the install disk rather than the internal drive. The reason you want to do this is two-fold: firstly that if it boots OK that way, it shows the basic hardware is OK, and secondly, it's possible that the hard drive has developed errors (likely directory damage) and the tool to check for that and attempt to resolve it is on the install disk.
Once you've got the system booted to the install disk, exit the installer and run the Disk Utility application. That should display the internal drive (and the install disk) on the left. Select the internal drive and then click 'Repair Disk'. If no errors are found, the drive is fine and the problem lies elsewhere. If errors are reported and the disk is fixed, then you should be able to reboot normally afterwards. If errors are found and Disk Utility reports 'error on exit' not having fixed them, then run it again just to be sure, but otherwise it means the drive is damaged sufficiently that Disk Utility can't fix it. A third-party application such as Alsoft's DiskWarrior will then be needed if you want to try and fix the drive and recover data, or you can simply elect to do an erase and install, meaning the drive will be reformatted and a new copy of MacOS installed. Do not do this if you have data you need to get off the drive!!

IMac randomly frozen at grey Apple logo screen.

Hi Guys,
I need your help.
My iMac randomly freezes at startup, at the grey Apple logo screen... some vertical black bars appears, the image is unclear and doubled. The round icon showing that the system is loading freezes. Some times, a black screen appears asking for the computer to be restarted.
I need to power off the iMac for 7-8 times and then it comes to normal till the next boot.
One time, a month ago, the same happened when I was already in leopard, but since then nothing. Now, in the last week, it's happening in 80% of the startups.
Any idea?
Thanks !!!
Andrei

1. Have you installed any third party RAM? If so try removing the third party RAM and install the Apple original RAM for testing.
2. Disconnect all external devices during testing. This means hard drives, ipods, printers, scanners, and hubs.
3. Boot to your install disk. Insert the install disk and hold down the "c" key at startup. Once it boots up select your language but instead of going through the install process go to the Utilities menu at the top select Disk Utility. Select your hard drive/Mac volume on the left then under the First Aid tab click Repair Disk. If that passes/repairs successfully Repair the Disk Permissions. Once this is finished go back to the Utilities menu, select Startup disk, choose your Mac OS X volume and click restart.
4. If you are still having issues insert your original gray iMac install disk, restart and hold down the "d" key. This will boot you to the Apple Hardware Test. Run the Extended test.

My 2009 iMac gets stuck on the grey Apple logo when booting up. It boots correctly when in safe mode. I have tried erasing the HD and re-installing from a USB installer. It says the install is complete, but after restarting it gets stuck on the Apple log

My late 2009 27" iMac gets stuck on the grey Apple logo when booting up. It boots correctly when in safe mode. I have tried erasing the HD and re-installing from a USB installer. It says the install is complete, but after restarting it gets stuck on the Apple logo again. This could possibly be an HD failure, but then why does Safe Mode still work and the USB install not work? Any ideas?

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it.

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with "Model Identifier." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

HT201412 Iphone 4s is frozen on the black apple logo screen. have tried to hard power off but it will not turn on. Have connected to computer but device it is not recognizing the device so can't do an itunes update. any suggestions?

My phone is frozen and I can not get it to "Wake up"
Stuck on the black apple logo screen. And my computer and itunes are not responding when I plug it in.
Any ideas?

try doing a restart / reset first

if this doesn't work
You can try the step here in this link.
http://support.apple.com/kb/ht1808
when you're stuck on the apple logo, the operating iOS doesn't load so itunes could not detect the device

PowerMac G5 & Display starts but after the grey Apple logo screen dies
