Ok I have the dreaded black screen when I turn on my iMac but unlike most of the posts regarding this topic the HD doesn't seem to spin up. All I can hear is the fan, and no other activity.
It started with my screen freezing and the only thing I could do was to turn off the computer. This has happened a few times in the past and turning off and on always seemed to resolve it. But this time when I turned it on all I got was the fan noise. No chimes, nothing. I've tried resetting the PMU and removing the extra ram but know luck.
Most people seem to think this is a logic board fault, but then they seem to have an active computer just with no display. Any ideas greatly appreciated ?
Many Thanks

Sounds like you've done your reading!
Given that your hard drive doesn't spin up I would be very suspicious. Could you confirm that your iMac shows any signs of life?
Does the caps lock light work?
Do you get the start-up chime (or beeps)?
Do you have the display adaptor to see connect your iMac to a TV and test it?
When you said 'started with the screen freezing' do you mean Kernel Panic, blank screen or the SBBOD?
I regret When I had similar symptoms a new logic board was required (at £325 plus fitting).
To answer your question on Part No.s:
Unfortunately doumentation on the iMac G4 20" is sadly lacking as they only existed for a few months (Nov 03 - Jul 04). The 20" was just a heavy version (heavy so it doesn't topple over) of the 17". I guess the larger display may require a larger PSU though.
Just done a search on AMP.co.uk and it came out with this part number: (661-3104)which is different to the 17"/15" PSU part number.

Please Help: Won't Start, Just Spins
I am writing about my other laptop, a 15 inch MacBookPro 2.16 Intel Core Duo running Mac OS X 10.4.10.
I just downloaded the latest software update form Apple: iTunes Update and Quicktime Update (? I'm sure about the iTunes. Second could have been Quicktime or Java update? But it was done through the Software Update)
I updated as instructed, then the computer was rebooted. But since then, it will only spin. The Apple logo comes on with the grey background and the spinning wheel.
I've let it go for over an hour.
I've tried to restart several times.
I've removed the battery and power and tried to restart again.
I've tried "minimal boot" by pressing down the spacebar while restarting.
Nothing seems to work. It just does the same thing again. Goes to the Apple logo against the grey background with the spinning wheel.
I'd appreciate any help! Thank you.Based on your description, it appears that your system directory may be corrupted. Perhaps try rebooting from your backup system disc that came with your Mac, and run the Disk Utility, “Repair Permissions”. (see User's Guide)
There are other possible solutions although they will require more evasive steps and/or resources you don’t likely have on hand. Some of us use Disk Warrior specifically for this kind of issue. Also, if you're near an AppleStore, then perhaps they can help. Worst case would be to reformat/reinstall the OS or similar.

My Imac won't start, just get the chime and white screen.
I tried holding command R but nothing happens, just a white screen! What can I try next?
I don' t know what model or OS I have...should dig out my paperwork...Thanks SO MUCH! I am having nightmares about all that could be lost. If the fan can be fixed, then I can cope with the backing up and maybe relieve the hard drive so it gets faster. As Murphy's law would have it, I just bought an external drive but haven't had a chance to set it up to automatically back up. Your reply makes me feel much better... There is hope that I can lip along with this old iMac until I can afford a new one.

My iMac won't start...just beeps. What do I do now?
My iMac won't start up anymore. When I hold down the power button for 3 seconds and then let go al it does is beeps 3 times and then pauses for about 4-5 sec. , the 3 beeps and pause, and so on. Everything was working fine. I shut down the computer and now can't geitback on. Is it ruined?
Three beeps at startup indicates bad or loose RAM.
You can look up videos on how to replace RAM on your model Mac, at YouTube, or Other World Computing. -
IMac won't start up passed the grey screen
Last friday my iMac (late 2006, 24", 2.33 duo core Intel, OS 10.6.8) gave me the spinning beach ball.
Restarting resulted in: first the apple screen with the progress indicator, followed by grey screen..
That was it. It hangs at the grey screen.
I've been busy this weekend testing all kinds of ideas to get my imac to fully start up again.
I checked the RAM, it's fine.
I flushed NVRAM, wild guess, but nothing changed.
Starting up in safe mode doesn't work.
Starting up in recovery mode doesn't work.
On the upside, I was able to start my imac up in Target mode. Using the host computer and Disk Utlity I can see there's nothing wrong with the HD. All the data is still there!, so later today I'll make a copy of the complete HD, hoping/thinking that I won't copy whatever is wrong.
I had Disk Utility repair all the permissions.
I've used the host computer to reinstall the OS on my imac.
But on start up my beloved iMac still won't get passed the grey screen.
I'm thinking something goes wrong before my Mac even gets to the HD. Maybe it's the firmware, but I'm not really sure that firmware matters in this case. And I wouldn't know how to reinstall the latest version of firmware because my imac won't start up from it's disk drive
I'm thinking maybe something could be wrong with the graphic card's RAM, though on start up I can see the apple logo just fine.
I'm not able to start up from CD, I've tried that because I wanted to reinstall my OS (before I figured out how to do that in Target Mode) by putting the OS disk in my imac's own disk drive. Staring up with the C key still gets me the grey screen. Staring up with Option key shows no other option but the HD.
So is there anybody out there who has an idea that could help me further along?
Any help is greatly appreciated!
FrankHi Jan,
If you have another firewire Mac you can check if the HD of your Mac is OK by connecting them with a firewire cable and use target-mode. That way I found out my HD was just fine.
It also offers you the chance to run a diagnostic program to check if anything else is fine. I used TechTool to do that. But everything checked out fine.
In the end I decided the problem is probably hardware. Some electronic part that broke. Very frustrating that some small transistor or so is keeping me from using my otherwise fine iMac.
I contacted a repairshop that also works for the local Mac retailer. They told me my iMac was concidered 'classic' and therefor it wasn't economically not worth the trouble trying to repair it.
I gave up, took two weeks to mourn the loss of my beloved iMac, and bought a Mac mini.

24" iMac won't start when iPod is connected
My 24" iMac won't start up/restart if my iPod is already connected to it. If I restart with the iPod connected, I just get a gray screen (with no apple logo) forever. Has anyone else experienced this problem? If so, any solution? I have Windows installed with boot camp, don't know if that's the problem, but I tried reseting the p-ram, but to no avail...
Intel iMac 24", 7600 GT, 500GB, 2GB. Titanium Powerbook 667 MHz G4, loaded. Mac OS X (10.4.7) 30 GB iPod VideoMy suggestion would be disconnect the iPod. That's just me though.
http://docs.info.apple.com/article.html?artnum=93953
I'm guessing Boot Camp is the culprit. Whatever emulated BIOS it's using doesn't like the iPod as a startup disk. -

Hope this helps . -
IMac won't start - should I reinstall OS?
Recently my iMac won't start up - it goes to screen with folder + question mark. I've run Disk Utility, repaired hard drive, but there were no reported repairs to make.
Occassionally it will start up, and everything seems normal until suddenly the beach ball appears and everything freezes. 99% of tries it won't start up (i get the ? folder). Is it worth erasing the disk and reinstalling everything to see if a fresh start will help, or is it likely that the hardware is damaged?
Don't want to bother erasing it if there's no point... any advice greatly appreciated.
Also - anyone who's had their iMac repaired - what are the costs like?I've just suddenly had the same problem - for no apparent reason as far as I can tell. The night before last I switched off my iMac as normal, and yesterday morning switched it back on. At first it would start, but crashed as soon as I tried to start any applications. Then it wouldn't start at all, and just got as far as the gray screen with the apple on it. After trying resetting the PRAM, switching on and holding the on button for 10 seconds, it was no different...
So, I tried doing a archive-reinstall from the original leopard DVD I bought from apple. This did a successful disk verification, but then said it couldn't install mac os due to a problem with the basesystem package. After that it wouldn't let me try another archive-install and only gave the options to install as new, or erase and install. The latter I don't want to do, and the former just gives the same basesystem error... All I get now is a flashing folder with a question mark and not even the gray screen...
I have tried using the diskutility to verify/ repair the hard drive and it says all is well...
I have heard this may all be due to dodgy RAM chips, but I have never messed with them or altered them. It just seems odd they should suddenly fail when they were working fine before.....
Any ideas would be much appreciated. A lot of data at risk

Imac won't start up n issues in single user mode
Imac won't start up after long time 'frazing' of Firefox. Manual start up ended up in the grey screen forever'processing' icon.
Had a look at other solutions, unable to enter safe mode. Someone mentioned to try single user mode and it went through half way with error messages on the screen which has no command line available for me to key in any letter.
My Imac has been out of warranty coverage for a while, how do I know if it's hard ware problems before paying for service?
Any help would be appreciated!
AliceYes, I have backed up and deleted old files using target disk mode with an old macbook. It's just the larger files I didn't have enough space and disks for. I really appreciate your help on this as I've never had any mac issues before this so am not really sure what to look for.

G5 iMac won't start! Help needed.
Got a new intel iMac. Gave my husband my old G5 iMac (not intel). It was working perfectly. For some reason unknown to me, he decided he was going to reinstall everything from scratch so he grabbed the first disk he saw and put it in the computer. It was the startup disk for an intel computer & NOT for the iMac G5.
Did he fry the computer? It won't start up. Keypad & mouse won't respond.
The screen can't find the driver (no surprise) and says "panic: we are hanging here...." I can't get the disk out of the drive. Service contract is up. Is there a way I can connect my laptop to it and get it to respond & spit out that intel disk? Perhaps if I open the cover up, I can into the CD drive and get the disk out. All ideas appreciated.Quote

Hi Mel Kev
Have you tried holding down the left mouse button when you turn the computer on. Holding down the left mouse button should force eject the disk.
Hope this helps

And it WORKED! (I really wasn't in the mood to do surgery on the computer this evening). Thanks all!!! You are awesome!
Now, if I can just find the original installation disks.... They are in this drawer somewhere.... -
Intel iMac won't start - HELP!
My iMac won't start this morning. I get the white screen with the grey apple,
and the swirling progress thing, then after a few seconds I can hear
the sound you hear when the system shuts down. like a soft switch
going off, then it just continues swirling, still with the white
screen and grey apple, then it restarts by itself. Then we go through
the same routine. Tried booting up by holding C with the Leopard disc inside but nothing happens.I have just reinstalled Leopard as Snow Leopard left too many printers and programs lifeless, so I did an erase and install a few days ago. Since then I have used the Mac fine, switched down normally last night, but this morning it doesn't want to play.
Any thoughts?
Thanks in anticipation
Chris

Do this first

and then do this, if the PRAM does not help
http://support.apple.com/kb/HT1543
The second one is basically disconnecting your iMac from power (and all cables), then reconnecting following a precise procedure.
If that does not help, I would restart with the Snow Leopard installation disc (insert disc and start up with the C key held down). You probably did an installation of Snow Leopard over your existing Leopard system the first time. This time, erase it completely first, then install Snow Leopard. I assume you backed up your data already.
When you get to the Installer screen (after selecting language), go up to the menu bar. Under Utilities, select to run Disk Utility. In the sidebar, select the internal DRIVE, not the volume indented under the drive. Go to the Erase tab. Name the volume +Macintosh HD+ and set the format to +Mac OS Extended (Journaled)+. Erase the drive. Since you have the drive selected in the sidebar (not the volume), it will also re-partition the drive.
It should take less than on minute to complete the process. Quit Disk Utility to go back to Installer. Run the standard installation onto the blank internal drive. Hopefully, a fresh Snow Leopard install on a reformatted/re-partitioned drive will work better for you. -
