EMac Power PC G4 won't start up

I just bought an iPod and tried to start it up with my eMac Power PC G4 running 10.3.9. It wouldn't work and soon after I encountered the following start-up probelm:
The computer comes and I get the gray screen with the Apple logo and the spinning wheel (NOT the colored spinning disc but the gray spinning wheel). Start-up does not progress past this point.
I tried to reinstall the earlier version that came with my computer but this also crashed. I've also tried Disk Utility and have got some error messages.
I have a lot of info I do not want to lose. What can I do?
Thank you very much in advance for your help.

Welcome To  Discussions steverooth!
"I have a lot of info I do not want to lose."
Do you have a backup?
"I tried to reinstall the earlier version that came with my computer but this also crashed."
Hopefully this has not further compromised your data.
Do you know what size the Hard Drive is, and how much space is available?
Disconnect all peripherals, except the keyboard & mouse,
Run Repair Disk, and report the results here.
THESE ARE THE STEPS FOR USING DISK UTILITY TO REPAIR YOUR HD
1.Insert the System Install disk, Mac OS X CD-ROM disk, or Restore DVD disk, then restart the computer while holding the C key. Use the System disk, of the OS, that is currently installed.
2.Once started up from CD or DVD, on the Menubar at the top of the screen, choose Disk Utility from the Installer contextual menu.
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from disc 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, if necessary.
6.Click Repair. If DU reports errors it has fixed, re-run Repair Disk until no errors are reported.
7.Repeat steps 5 & 6, but select the Hard Drive this time. It's usually the first listed with the manufacturer's model number. Make note of the S.M.A.R.T. status.
8.When finished, select Quit Disk Utility from the Installer menu.
9.Select Quit Installer from the Installer menu.
10.In the resulting pop-up window, choose restart.
11.After the computer has restarted, you can eject the CD.

Help!! My Power Mac G5 won't start up!!

I was working on my computer when all of a sudden everything froze. I tried all the key commands and no response. So, I held the start button until it shut down. Then when I tried to start it back up again after a few minutes, by pushing the start button, only the fan starts. No start up chime. Nothing on my screen. Then the fan starts getting louder and louder like it going to explode! I quickly held the start button again until it shut down. I read through the manual and tried everything it said and still the same thing. I read through alot of the questions and answers on this forum...found alot of similar questions, but no answers that I can use. I tried replacing the surge protector, but still nothing. My business & life is on this computer and stupid me, I didn't back up much! Help!!

"Disk Utility 10.5 Help
Testing and repairing your startup disk
If you have problems with your startup disk, you can use Disk Utility to test and repair it. To do so, you must start up from another disk, such as your Install Mac OS X disc.
Start up your computer using another disk.
To use the Install Mac OS X disc, insert the disc and restart your computer holding down the"C" Key OR (Option key and then select the Install Mac OS X disc and click the arrow).
Open Disk Utility.
In the Mac OS X Installer, choose Utilities > Open Disk Utility.
Select the startup disk you want to repair in the list of disks and volumes, then click First Aid.
Click the button to verify or repair the disk or disk permissions.
Check the S.M.A.R.T. status of your hard disk at the bottom of the window. If it shows "Verified," the disk has nothing wrong at this time. If you see "About to Fail" in red letters, back up your files on the disk as soon as possible and replace the disk."

"Troubleshooting: My computer displays no video
If your computer won't display video, here's how to troubleshoot it. Please keep in mind that although your computer may display similar symptoms that prevent it from turning on, this article discusses what to do if the computer won't display video, meaning that when you press the power button:
You may hear a startup chime
You may hear fan or drive noise
You may see the power light on the computer light up
If your computer does not turn on, when you press the power button:
You won't hear a startup chime
You won't hear any fan or drive noise
The power indicator on the computer won't light up at all
If your computer is not responding at all, see the Troubleshooting: My computer won't turn on article instead.
If your computer won't display video but you can hear a startup chime, fans, drive noise, or you see the power light turn on, the first question is whether you have an external display attached (such as a Power Mac G4, Power Mac G5, Mac Pro or Mac mini) or if the display is built-in (such as an iMac, eMac, MacBook, MacBook Pro, iBook or PowerBook).
For external displays
Try these steps to resolve the issue:
Make sure that the monitor is turned on and has power. Make sure that the display's power cord is plugged into a working wall outlet, and that it's properly connected to the power adapter. (To check if the wall socket is working, plug in a lamp or other electrical device.)
Check that all video cable connections to the computer video port and to the monitor are properly connected.
Examine the pins on the video cable connector to make sure they are not bent or damaged in any way.
Connect a known working display (if you have an extra one available). If you see video after doing so, replace your old display.
Reset the computer's parameter RAM. (Click the link for instructions.)
On a Mac mini, reset the computer's PMU. (Click the link for instructions.) For Power Macintosh G3, Power Mac G4, or Power Mac G5 computers, check your user guide for the location of the PMU reset button on the logic board.
Next we're going to check to see if the computer has video when started up from a disc:
Find the Install or Restore disc that came with the computer. Insert the Software Install and Restore disc into your CD/DVD drive. The disc may look something like the picture below.
Shut down your computer.
Once it's off, hold down the C key on the keyboard and start up your computer. This will start up the computer from the Software Install and Restore disc instead of your hard drive.
If you see video when started up from disc, you may have corrupted software. You can use the Archive and Install feature of the Mac OS X installer to reinstall. This kind of installation gives you a fresh version of Mac OS X, but you don't lose any data from the computer as your old information is all archived.
If you tried all of the steps above and the computer still won't display video, contact Apple technical support (1-800-APL-CARE in the U.S.) or take your computer to your local Apple Store or Apple Authorized Service Provider (AASP) for diagnosis.
For built-in displays
Try these steps to resolve the issue:
Make sure that the power cord is plugged into a working wall outlet, and that it's properly connected to the power adapter. (To check if the wall socket is working, plug in a lamp or other electrical device.)
Make sure that the power adapter is properly connected to the power port on the back of the computer.
Reset the computer's parameter RAM. (Click the link for instructions.)
On an iBook or PowerBook, reset the computer's PMU. (Click the link for instructions.)
Next we're going to check to see if the computer has video when started up from a disc:
Find the Install or Restore disc that came with the computer. Insert the Software Install and Restore disc into your CD/DVD drive. The disc may look something like the picture below.

Power Mac G5 won't start up and is beeping

Dear friends,
This morning, my Power Mac G5 started to beep. When I try to restart it, it beeps some more and also makes a clicking sound like a metronome.
The computer won't start up anymore. At startup, it displays a grey screen with a little folder in the center that flashes a question mark and a finder icon.
What is wrong with my excellent computer, and how do I fix it?
Marnie

Marnie Glickman-
Could be a variety of things, but most likely your hard drive is not happy. The flashing question mark means that the system is trying to find a working disk with a valid system on it. Should be the hard drive. Isn't.
Launch from the install DVD of the latest OSX system you have. Under the Apple Menu should be the Disk Utility. Launch it and try repairing your hard drive and see if that does the trick.
If not we dig deeper into this excellent problem.
Luck-

Power Mac G5 won't start up after a security update, please help!!!

Hi all,
My Power Mac G5 version 10.4.11 keeps showing a black video, no beep, no start up chim, this occured after updating a security patch 2008-7 from Apple website, asked to reboot then I encountered this mess.
The powerlight is turn on with solid white color. My display also has its powerlight turn on with solid white. But not nothing happens, except the fan noise becomes gradually louder and louder. I wait for hours ... but ...
My system just won't start up. Although I tried to reset the SMU, reseated RAM...
I tried also to re-install the OS by CD but it's impossible to insert it to the DVD tray.
Any help is greatly appreciated, thank you for your time.
Sgmed.

Hi BDAqua,
After weeks of strugle I can use my MAC as normal, but everytime I shut it down, she cannot wake-up, I had to refer to your hints in order to start it up again. So right now I can use my MAC every day with "SLEEP" mode.
She just cannot RE-START or wake up after a SHUTDOWN.
Any suggestion is greatly appreciated, here under I pasted the log file retrieved from Disk Utilities.
(I tried also to reset PMU, SMU and PRAM but nothing helped. Perhaps she is in need of a brand new PRAM battery???

HELP! Battery drained and now, even with a power plug, computer won't start

My battery drained completely...and I went to charge it. When I plug the power cord in, it shows "green" not "red." When I remove the battery and just plug in the power cord, the computer won't start either.
Anyone encounter this before after a full battery drain? It's very odd.

I had the same green light non-charging problem. Turns out, I had to replace my wall adaptor. A dealer will have a good power supply you can try.

Dual 1.8Gb power mac G5 won't start up. No chime or video.

I have a dual 1.8Gb power mac G5 that won't start up after the weekend. The computer was being run as a server using OSX 10.3. When my employee came in on Monday she said the fan was running full blast, but there was no video and the computer was totally unresponsive. The computer has been restarted with and without periferials plugged in, reset the PRAM and SMU/PMU/Cuda switch. Tried different monitor. I've put the hard drive in another G5 and it worked fine. I've also noticed that this computer does not click (sounds like a relay) when plugging/unplugging the power cord. I've always noticed my other G5 does this. Any ideas? I'd like to try and fix it myself and save the "Apple Authorized Service Provider" costs. Thanks!
Eric

It doesn't seem to matter if anything is hooked up or not ... mine nor his. I've tried three different power cords in two different locations. I wouldn't know what to "tighten" inside.
Most recently at home I've tried using just the mac keyboard an mouse connected to there own USB ports off the back of the CPU and then the Apple 17" studio display from the ADC output. Still nothing. I then tried the same setup, but with a 17" CRT monitor using the DVI output and the adaptor (finally found the adaptor). It booted up fully once, but then died (I wasn't there when it happened, but when I came back no video, fans on full, and unresponsive). I hadn't had any more success until this morning when I tried to fire it up again, and it came on, but with distorted video (the one that says you need to restart your computer). I'm beginning to think this is a bad power supply problem due to the specific component failure (same bad capacitors as the iMacs), but mine doesn't quite fall within the serial number range (just before).
Thanks for the help!

Power Mac G5 won't start even after Repairing Disk and Permissions

I Repaired the Disk first by booting from the install disk and it did repair 1 item and then tried to reboot into safe mode to repair permissions and it didn't boot. I restarted by booting from the install disk again and repaired permissions and it seemed to repair alot of stuff. But it still won't start up.
I get stuck at the blue screen with the apple logo above a status bar that never moves.

Hi Larry,
Appears to be time for An Archive & Install, which gives you a new OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space...

Power Mac G5 - Won't start up with the beep noise.

Hi all,
I am wondering if someone can help me with my problem. I've just gone to turn on my G5 after dusting out the inside (i unplugged the power supply and then lightly dusted the inside) and now it won't turn on.
The power light comes on, but there is no beep, and the fans start, but they gradually get louder. The white power light then flashes once in a while
Can anyone offer any help please?
thanks
Mark

Well - as long as you have pressed the button firmly once, that should be it.
I did wonder if you had disturbed the RAM while you were rummaging inside - is there a pattern to the flashes of the white power light, as described at the bottom of the page here
http://docs.info.apple.com/article.html?artnum=302527
If not, as the mains power has been disconnected, it's just possible that the internal back-up battery may need replacing

I have a Power Mac G4 (dual 1 GHz with 2 GB of RAM) running OS X 10.4.11. It has the mirror drive doors and was once referred to as the “wind tunnel”.
The problem is that it will not start up after it has been shut down unless I first push the reset button. I have tried replacing the battery and resetting the p-ram. When I try to start it without first pushing the reset button nothing happens. The light for the start button doesn’t even come on. But if I disconnect the power, open it up and push the reset button it will start up and run perfectly.
Thank you for any suggestions that you might have.

Thanks BDAqua, it does sound like a bad capacitor. The PSU is one that I put in a few years back when Apple was giving them out so as to reduce the fan noise. I kept the old one until last week when I sent it off to be recycled. I suppose it would be a tough job to find the bad capacitor and I doubt that I would have the skill to replace it even if I could find it. It's not like I really need this power mac since I have a Mac Pro 1,1 but I do occasionally want to run something in OS 9 and I do love this machine for what ever reason. There was remarkably little dust inside but I went over it with a can of dust remover.

Power Mac G4 won't start - no activity except light.

I have a Power Mac G4 (1.25ghz, 2.25gb RAM, 80gb HDD) that is having somewhat of a strange problem. Basically it's not powering on at all, the light powers on when you push it but once released it goes out. No sound, no fans, no other activity. However if you hold the button in the light will stay on. It's almost identical to the problem this gentleman had:

No I have already tried reseating all the connections on the board (power, RAM, GPU, etc.), tried booting it with only the original 256mb DDR stick of RAM, booting with known working RAM, and resetting the PMU.
I am thinking at this point it may have to do with the PSU, but I thought I would post here to see if anyone had any other ideas. Apparently I am not the first person to have this issue and was wondering if anyone here had something similar, and how you resolved it. Thanks!

It can be due to the button itself. See this:
http://support.apple.com/kb/TA27071
The power button lives on a separate component called the "front panel board." or "FPB" hereafter. They can fail, and are a much cheaper fix than a new PSU of logic board.
An Apple tech at a nearby college told me a way to test for a bad FPB. It requires that you find one of the original Apple USB keyboards that came with the first iMacs. It's model M2452 and, unlike newer keyboards, has a power button much like teh older Apple ADB boards.
The tech said that, when using the old iMac board, the power button overrides the buton on teh FPB and should start the computer if only the FPB board is bad. If the keyboard switch does not work, then there is something more expensive at fault.

Will Power Up! Won't Start Up! HELP!!!

Weirdest thing I've seen(well almost) in all the years I've owned macs.
I have a 15" pre-2008 MacBook Pro. It has 10.6x installed. After shutting down the other day I wiped down the laptop(just a dry clean cloth), including the keyboard. Went to bed. Next morning the computer powers up and no start up. The sleep light is on. I have tried on suggestions from apple help. I cannot access anything because there is no software running. I also put my original 10.6 disc in to no avail. Makes no sense to me. Did it just die on me or are there other evil spirits at work. Please join me. Thanks. R.T.

Hi r,
Need some clarification. After inserting the install disc, did you hold down the power button for 5-10 seconds to shut down the MBP? Did you then hold down the c key and push the power button, still holding down the c key, and wait several minutes to see if it would boot? Have you tried a boot into Safe Mode? What else have you tried?

After power surge g5 won't start.

We had a power surge the other night. Now when I try to start my computer I get a message that says to hold down the power button to restart the computer and the fans start to run loudly. I tried starting in safe mode but that simply keeps the message from popping up. Ideas? Please help!!

It shouldn't affect that, but may not help is all.
Do you have the Install Disc for this Mac & OS?
"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."

Power Mac G5 won't start, no video Cinema HD 23"

Hi everyone!
One day my PM G5 decided not to boot.
I tried every keyboard shortcut, I changed the video card - I have the original and another one - and the PRAM battery but no change.
The first time I started after I changed the PRAM battaery it eventualy turned on and I saw the gray screen with the Apple logo and the spinning weel but after 5 minutes I turned it off because it did not finished the booting.
After that nothing. I tried to changed and swap the 8gb memory around and the 2 video card also but it didn't even get to the chime sound.
Than I started without any video card and it sounded the mac was booting and I heard the HDD loading all the fans were OK and so on. I can confirm it without the display.
If I put any of the video card in and restart I don't even geting the booting sound. After 2 minutes the fans are spinning faster and faster.
Is it the logic board or something else? Any idea?
Thanks for your help!

Hello,
Have you blown the dust out of it lately, especially the Video card CPUs, & Power Supply?
Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...
See which one your G5 has...

No power light at all...

It can show on any G5, and even many other computers & electronic devices of the period.

Power Mac G5 won't start up (glitching screen)

For the entire day my Powermac G5 (late2005) model has been performing poorly until eventually the screen freezes and a dialog box pops up that says I must hold down the power button and restart my computer. I think this has been happening since I installed the new security update. Now when I start it up it makes the start up noise. begins to load, then the screen becomes glitchy and it freezes up.
Please help me I have a lot of projects I am currently trying to work on and this came totally out of the blue. Is this something I am going to have to ship my computer in to fix? if so how long will it take?
thank you,
Austen

Hello! Personally, I'm not big on updates unless it's to fix a major problem I have but anyway I would boot from the install disc and run the repair disk function. If you get it running the first thing to do is get your data off in case it's not backed up (which I'm sure it is?). You might also try a safe boot by holding down the shift key at startup. Once you have your data off of it I'd probably download the combo updater so you can run the stand alone updater as opposed to running the software update control panel. Also be sure to repair permissions before and after any future updates. Post back and let us know how you are proceeding. Tom

Power Mac G5 won´t start

Hi,
when I went to bed last night I put the computer on sleep. This morning when I tried to make it start by moving the mouse and pressing the keys on the keyboard nothing happened. The led is on, but is on steady, it doesn´t slowly blink as usual.
I tried to turn it off, but the light doesn´t go off. I can´t hear the fans and the cd tray does not open. I unplugged it and then, the led did go off but when I plug it back in, the led comes right back on without any other sign that the CPU is working.
I tried to plug it into another mouth and it does exactly the same thing.
Any ideas?
Thanks for the help.

Is it the original battery?
I would check it first. When mine went, I had no response from my Mac at all; just a light on my power button; absolutely no boot at all.
Check out things in Texas Mac Man's Battery, PRAM, PMU tutorial on the subject. His tutorial is a little dated (don't believe it even mentions G5's) but the info in it, except SMU not being included, still applies. DALE
