IMac G5 froze and now it wont boot? Help!

I have iMac G5, its 3 years old. I was playing a game and all of sudden it froze.
-First tried to resarted the computer, it wont boot up and there was no sound.
-Secondly, I manage to reboot, but it gave me the gray with Apple Logo and did not reach to the login screen.
-Thirdly, it booted up, though it was very sluggish and slow.
I manage to use Disk Utility, it seem to be fine. I shut down the computer it just froze.
I restarted the machine nothing, just a black screen. Only once I turn on with sound, still black screen and the FAN started to rev-up. I took out Ram from the machine and to see if I can restart it. I get power, No sound, and no gray screen. I have no clue what happen and how to fix it.
Any tips will be appreciated.

Thanks

Well, you could try booting from your install disc, and either running Apple Hardware Test, or using Disk Utility to try and repair the drive, but I still think it's the logic board:
1. Insert the Mac OS X Install disc that came with your computer, 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. (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. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.
Then if possible, reboot and run Permissions Repair from your hard drive.
Let me know if you manage to revive it.

Imac G4 wont boot past grey screen desperatly want to fix it!!!!

Hi there,
Please can someone help.....
I got a Imac G4 at the weekend for a bargin, but it wont boot up. When i turn it on it makes the noise and comes up with a grey screen with the apple logo and the loading circle. It doesnt go past this screen and after about 15 mins turns itself off.
Any ideas how i can get this running again (havent tried anything yet to be honest as im not sure what to do). I love these machines as i just think they are querky and would love to get it working again to use as my home pc (as even though its old it will still probably be quicker than my old microsoft laptop)
Thanks!

Did you try a PRAM reset?
http://support.apple.com/kb/ht1379
>I can't get the disk drive to open either
If the optical drive tray cannot be opened, what happens if you hold down the mouse button during startup?
As a brody indicated, a faulty hard drive cannot be ruled out. Instructions for removing this drive can be found in the ifixit.com guides as well.
If you can gain access to the optical drive, the best way forward would be to use an appropriate Mac OS X system CD in an attempt to start from that disc (holding down the C key).
If it is not possible to locate a correct system CD right now, another way could possibly be to try to boot from an Ubuntu CD for PowerPC instead (once again, holding down the C key) just to see whether the computer is capable of booting at all.

IMac G4 Wont Boot or Run Install DVD

As the title says really the iMac wont boot. You get the start up dong and the Apple logo appears but then it just sits there. It wont boot from the install DVD either. I have reset the NVRAM and PRAM and that doesnt help.
Any ideas?

Have you tried safe mode yet?

My 27inch imac (2010) wont boot ,

also if it does boot up as normal it might only go for a limited time and then freezes , i have done the hardware scan and it come up with no trouble found and also reset the pram about 100 times , tried to start in safe mode etc ..... done every combo of keys i can find referance to on the net and it still wont boot , exept randomly , also changed out the hard dive and the ram with known good units but nothing....... please if anone can help me before i go crazy that would be so cool.......... i also rang a local mac shop and the said that the logic board is stuffed and they will replace it for around $1000 ........ that is not an option.... and then the dude also said he will buy it from me for $300......... *** ...... maby he knows its an easy fix and is trying to screw me over....... anyone please help

You could have a failing hard drive. If you can, you need to backup all of your data.
Try and run Disc Utiity from your original discs or from your OS X 10.6 Snow Leopard install disc.
Try doing both permissions repair and hard drive repair.
If the drive reports any errors, then there is serious problem with the internal hard drive.
You could take a chance that it is not a logic board failing and purchase an external FireWire 800 hard drive and install a new version of OS X 10.6 Snow Leopard on the new drive, boot OS X from the new ext. drive and try to transfer/clone all of your data from your internal hard drive.
Find another Apple Store or another authorized Apple service center to bring your iMac.
When they do the diagnostics, If they find it's the Logic board, then you're out of luck!
You'll need to look for another computer.
If they find it's a failing internal hard drive, then you can have this drive replaced. The costs to replace the internal hard drive should not be too bad.

My macbook wont boot up :-( HELP!!!!

Hi
HELP!!! My macbook wont boot up.
I was deleting some files off my system last night, Id put them in the trash and deleted them (there was quite alot!!) and the screen gradually went black and told me i needed to restart my computer by holding down the power key.
I tried doingt this but it wouldn't restart.
I left it a while and tried powering up, it seems to turn over once but the chimes dont kick in and nothing happens, the little light (is it the sleep light?) does come on but nothing else.
I really really hope someone can help!

Since you are still using Panther, try booting from your System Install DVD. Try running the +repair disk+ & repair permission options.
See Article http://docs.info.apple.com/article.html?artnum=301287 My computer stops responding during startup
If you have AppleCare, suggest that you contact them.

Hi kinghamster678,
Can we get into the recovey mode ?Have you got a installation media or a recovery disk ?
Resettting the machine is the last option and we will lose all the data.We can try to boot from the installation media or a recovery disk.Then we can choose the recovery mode to have a repair.
"Startup Repair " ,"System Restore".

Now that i'm home I went to turn it on I get to the white screen with the Apple logo and then it goes to a darker greyer colour and I get this error

IMac G5 wont boot.

Hi guys, in my school there is a classroom with iMacs G5 and my job is to take care of it. So I decide to set firmware passwords on all iMacs. When I set firmware password on first iMac and I reboot it, that iMac cant boot to os x and single user even it cant boot mac os x installation disc. I reset pram and take off ram and nothing happens. What I can do? Version of os x is 10.4 Guys help me.

There are Support articles online at Apple's site which can help resolve the issue of a lost Firmware password; and how to set them correctly, depending on the hardware or machine series, or OS version.
Could be you did not do the process completely or in the correct manner of detail for it to work on that iMac G5. And depending on the OS X version, the means to do so can vary. An example of enacting Firmware protection is in the following page link:
•Setting up firmware password protection in the Mac OS X:
http://support.apple.com/kb/ht1352
•Enable password protection on your Mac:
http://www.macinstruct.com/node/507
http://www.thexlab.com/faqs/faqs.html
Since the powerPC G5 would be unable to run a system newer than Leopard 10.5(.8) the question of further upgrade is not entered into here; but for certain systems, oversight via Server software is almost always better when you have it. However old Tiger 10.4.x may be, that was a good system, and harder now to maintain since it is old, without updates, and relies on whatever third-party browsers, etc (tenfourfox) for any online access. The old server software would be hard to find, unless original DVDs were donated to the school.
There are other ways to secure computers, since anyone with physical access and time can remove an Admin password or an O.F. password. Articles for these older systems were on Apple Support site on how to secure Panther, Tiger, and Leopard, these were .pdf documents for download; maybe gone now.
I see how the need to protect the computers from such access before someone else, perhaps a student posing as a trusted administrator, for example. And I also see how anyone can ask questions and get answers to do this, before an authentic administrator could get around to doing so. That's why it is important to do the steps correctly; or avoid Open Firmware passwords if you can. Yet it is too easy with physical access to the computers, with a boot disc, etc to remove an Admin password. And a little harder for someone with a little skill, to remove the OF passwords set by an official who has authorization to control the Macs.
For greater protection, use physical controls in conjunction
with firmware password protection and encryption...
How to Password Protect Your Mac
How to Disable Automatic Login
How to Create User Accounts in Mac OS X
You may have to become an expert in troubleshooting hardware issues in those iMac G5s since that layer of difficulty is made worse by attempting the Open Firmware password in addition to having older machines, etc; and no server software to manage them in a group.
Hopefully you can work around issues as you find them...
Good luck & happy computing!

IMac G5 Wont Boot After Update

I just ran a software update and all I get now is a blinking folder/finder icon. I also have a disk in the drive that I cannot eject. I only have a bluetooth mouse and keyboard, so I have not been able to eject the disk in order to boot from the Mac OS DVD. Any help or guidance would be appreciated.

Welcome to Discussions - there is an extensive discussion, with fixes, for problems that occur after the updates HERE.
With respect to getting the disc out, try laying your iMac flat on it's face, on a soft towel, and pressing the eject button on the keyboard. Once you get the disk out, try and boot from your install disk.
Please let us know how you make out,
Miriam

I purchased a itouch 2g and i went to restore it and it wont boot plz help

i bought a itouch 2g model#A1288 and when i did a system restore on it because it had a bunch of junk on it it wont completely boot the apple logo turns to a skull and freezes please help i payed $200 for it off of some random guy so i cant get a refund

If you on OS X Mountain Lion, like if you purchased a recent Mac, you may need to head to Apple Menu > System Preferences > Security > General and set the downloads to "Anywhere". to install software from the web.
Also you need to check the compatabiity of the program your downloading with the operating system version your running. There seems to be a hardware requirement/license also.

Oh S_it, my intel iMac 2008 wont boot, flashing question mark is all I get.

Bought a friends' intel duo iMac 2008 which was working just find until a couple of day's ago and now when I try to boot it up all I get is a flashing question mark. I unplugged all components, including the electric cord and that worked the first time but now nothing. I don't have the startup or recovery disks. Must I have these...what's a girl to do? HELP!!!
Imac 2008 Mac OS X (10.5.4) previously owned, 2G

You don't need those discs, unless you need to test for Hardware, or reinstall the original operating system.
But you should get them anyway. Any software they installed on your machine, you should have the discs for as they are not their's to give away copies because of licensing restrictions.
The first step to try is zapping the PRAM:
http://docs.info.apple.com/article.html?artnum=2238
Then attempting a data recovery if there is no backup*:

If there is a backup, initially try to repair the directory*:
