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?

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!!

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!

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.
This is the other discussion: https://discussions.apple.com/message/15161427#15161427

My New iPod gets stuck on the Apple logo screen.

I got a new ipod but there is one problem with it. For hours at a time it gets stuck on the apple logo screen. In this state it does not connect to my computer. I cannot get it to play music because everytime I manage to get it started up the apple logo screen pops up and shuts it down again.
Also, on the occasions where my computer DOES recognize my iPod, my iPod says it has about 1 GB of "other files" and about 1 gb of "audio files". I understand the audio but I don't remember putting anything onto my iPod that wasn't audio. What are the "other files" and how do I remove them?

Other can be Album Artwork, Notes, Contacts, Firmware etc. or files that are on there if you are using the iPod as a removable storage device. If you feel that Other is being incorrectly reported then try restoring your iPod. Restoring will erase the iPod's hard drive, reload the software and put it back to default settings. Once the restore is complete follow the on screen instructions and it should connect to iTunes and give you a prompt to automatically update your library onto the fresh installation. If you want to update manually or using selected playlists choose no and it will default to manual mode and you can choose whatever setting you like: Restoring iPod to factory settings with iTunes 7

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.

Macbook pro stuck on grey apple logo screen - HELP! I've tried everything

I've looked through the forum for help and I think I've tried everything short of erasing and reinstalling mac os x -
- I've done an fsck (got "invalid volume count", "invalid node structure", "volume check failed" errors)
- booted from install disk and tried to verify disk (same errors as above)
- tried to "archive and install" mac os but got error saying "the destination disk must be erased for installation"
I tried T-starting my laptop connected to another mac (a powerbook g4) to try to backup my files before erasing and reinstalling mac os - but the mbp hard drive won't mount on the powerbook.
My latest idea is to try installing mac os x onto an external drive - and then booting my macbook pro from the external drive... and see if I get anywhere. my only concern is, I have to make SURE the option saying "Install Mac OS X - Installs Mac OS X for the first time" does NOT delete the contents of the external drive (it is a client's and cannot be erased!). I know there is also the option that says "Erase and Install" -- but I just want to make sure the first option will NOT delete the contents of an external drive.
Anyone know for sure? Or have any other suggestions? I have some work on my macbook pro that I cannot lose. Unfortunately I have not been backing things up... big mistake that I will not repeat.
Thanks in advance.

DiskWarrior is the answer, as sig has suggested. It can sort out directory damage that is well beyond Disk Utility's repair capabilities. If you already had a bootable external hard drive of your own, I'd urge you to buy and download DiskWarrior and install it on the bootable external drive, then run it from there to rebuild the directory on your internal drive. I have to say that using a client's hard drive to solve your own problem would be appalling and unconscionable, and I hope you'll forget that idea.
If you can't see your way to buying an external hard drive along with DiskWarrior, you'll have to buy DW on a bootable disc, or order one online and wait for it to arrive.
If you can buy an external hard drive of your own in addition to DiskWarrior — and I can't think of any better use for a credit card, if cash is short — then you'll be able to boot your MBP to a Leopard installer disc, install Leopard on the new external drive, and then buy DiskWarrior as a download (rather than on a disc) and use it as I described above. After sorting out the internal drive with DW, clone the internal to the external drive with SuperDuper or Carbon Copy Cloner, and there's your backup from now on.
I should add that although Western Digital external hard drives seem to be available cheaply everywhere, I strongly recommend against buying one. Seagate drives are also widely available, and would be a better choice.

My ipod touch regularly gets stuck on the apple logo screen and stays there until it runs out of battery, and even during charging. what can i do?

If the Home button is broken, best thing to do is take it in for repair, or get an estimate. Make a Genius appointment.

My iPod Touch 3rd Gen is stuck on the Apple Logo screen when starting up.

I've spent hours on this and it's driving me crazy. I've repeatedly tried going into recovery mode, DFU mode, and restoring (even using custom firmware) but it just won't work. Is there anything at all I can do to fix this?

Try:
- iOS: Not responding or does not turn on
- If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

My 4th gen Ipod nano keeps getting stuck on the apple logo.

My 4th gen Ipod Nano keeps getting stuck on the Apple logo screen, this happens everytime I plug it in to charge. I plug it in, an apple logo comes up, and it stays like that the entire time its plugged in. To get it to unfreeze, i have to press random buttons and unplug and re plug in earbuds. After 20-25min of doing this it unfreezes and I come to find it has gotten little to no charge after being plugged in for hours at a time. Any one else have this problem, and if so what do you do?

This can be a corrupted software/firmware on your iPod touch. If the recovery mode you did was not forced, then try to force it into recovery mode. This is how:
1. Force it to shut down (note: this sort of shut down should not be preformed unless you are in a situation like this because it is a hardware shutdown and will not attempt to unload software, save unsaved files, safely stop system processes, etc.) to do this, hold down the power/sleep button and home button for about 7 or 10 secs. Also I might be incorrect but I heard that you can just hold down the sleep and home button until the screen goes blank and then immediately let go.
2. Have iTunes running. Hold down the home button and plug the USB cable that came with your iPod into it. Keep on holding on the home button until a picture of a USB cable going into the iTunes logo appears. You are now in a forced recovery mode. (In case your not so tech-savvy forced recovery is the same as a normal recovery mode that an iPod might do if it knows an update or restore failed.)
3. iTunes should have shown a pop-up message about it found a iPod in recovery mode. Click OK, click your iPod from the sidebar and click restore. The iPod will show the apple logo for a while and iTunes will say "preparing iPod for restore" and then "waiting for iPod" this was the longest part of updates for me.
4. iPod will reboot when restore is completed. When I update my iPod it one time showed the apple logo for one whole sync until it showed the slide to unlock screen, so do not worry. P.S if that does not work do a DFU mode restore ( I've been told DFU mode stands for device firmware update mode) I'm running out of room, so google it. Hope this helped ;)

Stuck on the apple logo screen.

No one seems to have the problems I'm having with my ipod. I have the 16GB silver 4G nano, and it was working fine one day while I was at work, then it slipped out of my boss's hand and fell less than a foot, but it worked fine when i checked it. But a few hours later that night, I tried to plug it into my docker and it reset itself, getting stuck on the Apple Logo screen. I tried the 5 r's a billion times, and each time it resets it gets stuck again. I've let it die, and tried to replug it in. It'll show the 'connect to power' screen, but when i plug it in it just gets stuck again. My itunes doesn't even recognize the software, even though I always download the newest versions on itunes.
Is there something I can do? I really don't want to send it in to Apple because A. I don't know how much it costs to do that, and B. It takes forever and a day for them to return it to me.
I've had my ipod since November '08 to May '09 and this has never happened before. Should I replace it, or am I doomed to send it in to Apple?

Try force your iPad into Recovery Mode
1. Disconnect the USB cable from the device, but leave the other end of the cable connected to your computer's USB port.
2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the device to turn off.
3.While pressing and holding the Home button, reconnect the USB cable to the device. The device should turn on.
4. Continue holding the Home button until you see the "Connect to iTunes" screen. When this screen appears, release the Home button. iTunes should alert you that it has detected a device in recovery mode. Click OK, and then click Restore to restore the device.
Note: Data will be lost. You may have to repeat the above many times.

Sometimes iMac "stuck" at Grey Apple Logo during starting up...

Hello all.
I have this very intermittent problem with my iMac, it happens like here and there so I "don't really consider it now as a serious problem"...
My iMac has a FW800 external hard drive connected as a Time Machine drive, and two 7-port USB hubs connected (but not all ports are used up - namely iPhone, 3 iPods, printer, wacom tablet etc)
I have to stress I have not have any problem with this connection in my previous iMac model (all plastic white) and when I first got this iMac, until most recently.
*When I start up the iMac as usual, it will "get stuck" at the Grey Apple Logo screen*, I know that the mac has somehow "freeze" is because the animated scroll-wheel below the logo is not there (normally it will be there, "circulating")
The only option I have is to press the back Power button, *shut down the iMac and start up again, normally the 2nd start up will be fine.*
Anyone if you have any ideas or know what's going on, please let me know
Thanks and cheers

Sounds like some maintenance might be necessary (if it's not hardware related). Check out the xlab recommendations: http://www.thexlab.com/faqs/kernelpanics.html
My G5 iMac occasionally freaks out like that too, but I've done a complete erase and reinstall of the OS, so I think it's a hardware issue...possibly some weird RAM. You might do a test removing each stick and testing.

My ipod nano 4th generation will not turn on when i rstart it it gets stuck on the apple icon screen what do i do

Hello crimsonflare,
Try this first:

If that does not work, use this:

and try to restore you ipod.
Hope this helps.
