URGENT: iMac will not boot, next Mac shop 800km
State now:
I press the Power On, the tone (Dooooiiiiinnnnnggggg) plays,
the power light is on but slowly fades to dim
I hear the SmartDrive start up (there is a CD in it)
The screen stays dark,
there is no boot
After about 2 minutes the fan goes into hyperdrive
No system start
Last use:
I woke it from sleep,
Closed Safari
Closed Mail
Running was HP book composition/iPhoto/Skype (HP on top)
The cursor froze in place
I used the Power Off button
At restert I had as stated above.
No new programs installed in the last week.
Tried:
Holding the Apple key at startup > no change
Holding the Apple/Ctrl/R/P (as suggested in the quick guide)
Left it unplugged overnight
Still no change.
I really have a problem as I am in South Morocco and the next Apple shop is in Cassablance, 800 Km away. Fly to the Middle East tomorror for a week. Need to get data to take with me. Luckily updated all 10 days ago :-)

tried Apple/alt/p/r same as before. No boot, just the 'Boing' and a super-hyper fan after 2 minutes
When ever I have had freeze ups and used the power button to shut it down it takes ages to start up again. I also get the loud fan noise for about 5 - 10 mins. I think becuase you didnt shut down properly it needs to completely check the hard disk, this takes a while a requires a lot of cooling, hence the loudness.
Try starting it up and leaving it for a while, should be no more then 10 - 15 mins. Mine is usually about 5 - 10 mins
Everything should be OK, when you evenutally get in to a quick repair on permissions to be on the safe side
Let me know how you get on

I'll give it a go and get back to you in 20 minutes. This has never happened before though as this is my first freeze since I bought the mac (Oct 2005), and the fan I've never noticed before as it has been very silent running.
The CD should pop out and it should boot normally.
C
first things first, DONT PANIC...
Turn on your maching and hold down the left mouse button until the disk pops out.
If your computer doesn't boot up turn it off, insert disk 1 that came with your computer, turn on your computer and hold down the "c" key on your keyboard. You may very well have no problem booting into the disk. Next click "install", then when you see a menu bar appear (probably soon after). Click "Utilities" (in the menubar)>>then "Disk Utility". Right, now, when in Disk Utility select Macintosh HD in the 'left' source panel, and click "Verify Disk Permissions" down near the bottom. After that finishes, click "Repair disk Permissions". When that's done, from the menubar quit Disk Utility, and quit installer. Restart your machine, and again hold down the left mouse button until the disk pops out. At this stage your mahine should boot up just fine, if it doesn't, start to cry
If your machine boots up fine, run your software updater and install what they throw at you, and also download Onyx, it will make verifing and reparing disk permissions much easier in the future.
I'm so confident this will work for you, you're welcome!
don't have a left mouse button, just the Mighty Mouse.
I noticed that there was no power to the mouse (I had it connected through the keyboard). I've changed it to another USB port and it is now powered.
The disk I have in is Disk 1. Holding down the 'c' does not change the problem.
(how do I know if I have power to the keyboard?)
Pull the plug.
Leave for ten seconds.
Plug in.
Press power while holding down EJECT key on keyboard. Keep holding it down.
What happens?
C.
2) Holding down thw Eject key. Nothing new happens. There is the 'Dooiiiinnngggg', I hear the CD-drive working, the after about 2 minutes I have the hyperfan...
If I connect it to the Mac there is no power to the USB ports of the keyboard (tested with 2 USB devices)
If I connect it to the PC the keyboard works.
How does the Mac 'load' devices - i.e. Windows has drivers.
Could the problem be the Mac 'looking' for the keyboard? I'm really ignorant as to how the Mac works because it did just that - worked :-) not like Windows where you have to learn the operating procedures.
I am guessing that it is trying to boot from the CD.
Holding down the eject key - or the mouse button during boot - should force an eject.
But there are other suggestions here...
Good luck!

have to give up for now, got to pack.
I'll just pick up a new keyboard* then try again in a week.
*Maybe the kitten peed on it while I was out :-)
He needs to disconnect all peripherals and reset the power management unit. Doing that is different on the G5 iMac and the Intel iMac though.
The new keyboard is English, the old one German (keys in different places).
I tried to reset the language preferences (System preferences>Keyboard & Mouse).
The system froze for about 2 minutes then I got the message that I had to restart the system. On restart I got the Booooiiiinnggggg, then the black screen. I turned off and disconnected the power-cord for 5 minutes. Powered-up and the system booted but without the keyboard changes.
Any suggestions?
Still, happy to have my Mac back after having to use my old windows laptop - it was a bit like zipping back in time by about 20 years.
PS: if I disconnect ALL the peripheral devices, I suppose that includes the keyboard & mouse, how do I reset the power management?
SPOKE TOO SOON...
I worked away happily for 30minutes, was downloading my new mail and the system froze. After 10 minutes went inti screen.saver mode. The mouse, Keyboard nor remote could get it back into normal-mode. After 30 minutes went into sleep-mode- Not able to wake it. Powered-off, removed power-cable for 15 minutes. Try to restart and the Boing-Black screen mode again.
I have removed all peripheries and tried a restart, no good.
HELP! I'm back to my windows laptop!!
It's a G5.
I went to:
http://www.thexlab.com/faqs/resetpmchip.html
I pressed the Apple/alt/p/r (as I had done before with no response) and it restarted.
Fingers crossed...
Still, there must be a long-term solution for this problem, (if it's not solved)
