IMac won't turn on, totally dead after booting from CD

I have an iMac G3 DV 500 and it has been working great. I bought it used and it has 10.3.9 installed, no OS 9 no classic.
I booted from my OS 9.1 disc and was going to install the OS, but changed my mind. I selected "Shut Down" and the computer turned off. Now I can't turn it back on. Pressing the power button gets nothing at all, like the computer is not even plugged in. The power button is illuminated so I know power is getting in there. Did booting from the disc do something to the machine to render it inoperable, or did my machine just happen to die the moment I booted from OS 9?
iMac G3 500, iMac G4 700 Mac OS X (10.3.9)
iMac G3 500, iMac G4 700    

Additional info: I don't think the power button is illuminated. I think the plastic is just lighter in color.

  • My iMac won't automatically connect to wifi after waking from sleep mode

    After dowloading the newest software update and performing a firmware update for my Airport router, my Imac won't connect to Wifi automatically after waking from sleep mode

  • Imac won't turn on after anti virus software downloaded

    The Avast antivirus software was downloaded onto my imac and now my imac won't turn on. What should I do?

    Troubleshooting: My computer won't turn on
    Read and follow all the steps.
    If you find yourself at Step 6 determine if you can start the Mac in "Safe Mode":
    Safe Mode or "Safe Boot" is a troubleshooting mode that bypasses all third party system extensions and loads only required system components. Read about it: Starting up in Safe Mode
    You must disable FileVault before you can start your Mac in Safe Mode.
    Starting your Mac in Safe Mode will take longer than usual, graphics will not render smoothly, audio is disabled on some Macs, and some programs (iTunes for example) may not work at all.
    Merely starting your Mac in Safe Mode is not intended to resolve the problem, it's to observe its performance without certain additional components.
    To end Safe Mode restart your Mac normally. Shutdown will take longer as well.
    Remove the Avast garbage by using its uninstaller. Never install it, or anything like it, ever again.

  • IMac won't allow me to login after few hours

    Hi everyone...
    My iMac won't allow me to login after few hours. Actually I had a limited broadband connection which is free from 2AM to 8AM. So I have scheduled some downloads to start at 2AM and end at 8AM. Before going to bed, I just put on the screen saver. When I wake early in the morning and move my mouse.. blank screen turns on and colorful spinning wheel appears, but log-in window doesn't appear. This has happened thrice till now. Day before yesterday it was fine. But yesterday and today I got the same problem. Previously also it was working fine. I can't figure out why it is behaving like this...
    Initially, in Power save options, I scheduled iMac to wake up at 2AM and sleep at 8AM and then used to put iMac to sleep before going to bed. It was working fine and did the same thing for more than a month. Now I have removed wakeup & sleep scheduled options from Power save options.
    Following are the settings/options selected:
    1. In energy save options, I have selected the option not to put iMac to sleep when it is inactive for certain time.
    2. Put hard-disks to sleep whenever possible is checked.
    3. I have scheduled the downloads in Azureus, Transmission and Speed download 5.
    Following are the temps and rpms:

    One more thing, recently I have reset the SMU because it is taking too long to boot up. To my surprise, after restarting, fan (not sure which one) started to make bigger sounds. I then had to reset SMU two times and only then fan started to spin normally without any noise. I'm scared & worried...
    Someone please help me where I went wrong.... what can I do to solve this problem..
    You know I purchased this iMac for Rs.86000/- INR ($2097 approx.) ... after two months they slashed the prices by Rs.20000/- INR($487 approx.)... so this is how my luck seems to be

    Hello and sorry. First, if you reset the SMU. make sure you do not hold the power button down while reconnecting the cable or it will reset the SMC incorrectly.
    When you say you are logging in, are you logging onto the internet, or onto the computer/user account?
    If it is intermittent than it sounds like your internet and that would be best handled by your internet provider first.
    The following article is good for troubleshooting issues and you may wish to bookmark it.

    If it is your internet you are referring to than try going to the Apple in the top left corner and clicking on it.
    Than click on the System Preferences
    Then click on Network
    Then click on Assist Me.
    Then Assistant
    Maybe call it Test Location
    go through the steps involved and see the outcome.

  • My imac won't turn on a1311 intel core i3 late 2010

    Hey, today after a power off my iMac won't turn on, I've tried reseting it plugging it and holding the power button but nothing happens, im really worried, i have to finish an edition and have al native videos  there... HELP!

    you should definitely get a decent UPS to protect your investment.
    something like the APC Back-UPS ES 700 should suffice.

  • IMac won't turn on. Only a clicking sound and a grey folder with flashing question mark.

    iMac won't turn on. Only a clicking sound and a grey folder with flashing question mark.
    Help.

    Your iMac is actually turning ON as proven by the grey folder with the flashing question mark.
    The flashing question mark indicates that your system is unable to find a bootable volume. The clicking sound that you hear is probably coming from your hard drive while it tries to recalibrate. I suspect your hard drive has failed.
    What model imac do you have? If it's under warranty I suggest taking it in for service. Hopefully you've been maintaining a regular backup of your data as all users should. I lost my data once and it was a valuable lesson. I back up regularily now.
    If your iMac came with install disks then you can boot from them, choose your language when asked, then pull down the Utilities menu to launch the Disk Utility application. The Disk Utility application will allow you to verify whether your hard drive has an issue. Usually a clicking sound, assuming it's coming from the hard drive, is a sign of a bad hard drive.
    If your system has Lion installed then you can hold down the Command and R keys when you restart the system, then launch the Disk Utility application from the menu that appears.

  • IMac G5 fan always at maximum speed after booting into si...

    IMac G5 fan always at maximum speed after booting into single-user mode in 10.4.3
    Model: 1.6GHz iMac G5 with 10.4.3
    I updated my iMac to 10.4.3, then booted into single-user mode to do some cleaning at the command-line level. I know, as others have discovered, that in single-user mode, the thermal control is off, so the fan gradually increases up to maximum speed and stays there until you reboot or go into multi-user mode. Well, I have never experienced this one before, and I'm freaking out about it... I went into single-user mood one reboot after upgrading to 10.4.3, and after all the println white text lines ended, the [1] fan shot up to maximum speed in 0.35 seconds (it sounded like a high-pitched DJ record scratch during the time interval), [2] the fan stayed at maximum speed when I left single-user mode, and [3] I cannot get the fan to slow itself! I rebooted, shut down, and even tried booting off the Tiger CD, but the instant I hit the power button to turn on the iMac, the fans blast up to maximum speed. They shut down when I put the iMac to Sleep, but then they blast up again in full when it wakes up. I checked my settings in the Energy Saver preference pane, and I have the performance set to "Reduced," which is the lowest possible.
    I searched to see if anyone else had this problem or if the KBase had any info, but I didn't see any. I'm thinking about erasing and installing my stuff on the iMac, even though I just did that today.
    Again, this maximum speed fan problem is freaking me out. It just started when I booted into single-user mode in OS X 10.4.3. I have booted into single-user mode before (10.4.2) and have not experienced this fan issue. I repeat, the fans blast up to maximum speed after pressing the power switch to turn on the computer, so they do not even wait for the Apple logo to show up on the screen before blasting away. How can I get these fans to not do this anymore?!

    for the last few months my 20" 1.8GHz Imac has been very noisy - fans seem to run constantly and noisily. It might have been when updating to Tiger but I was never sure. Today, on the advice of a chat tech, I opened the case and reset the SMU to hopefully cure another problem. I noticed that all the air vents, intake and expel ones, were all quite heavily clogged up - not blocked but clogged with dust and fluff. I cleared it away mainly by blowing but also with a hand held hoover held close by. The exposed fan still as a lot of muck on it but greatly reduced and all the vents are completely clear. Having put everything back together again the iMac has been runnning quietly all day. May have been the SMU reset but equally might just be that the computer couldn'tdraw in cool air, circulate it or expel it properly and the fans had to work overtime to cope. Worth checking if you have noisy fans running at speed constantly.

  • IMac won't turn on after power cut

    When my iMac is unexpectedly turned off, ether at the wall or during a power cut, it won't then come back on immediately.  Sometimes it will come back on after an hour, sometimes after a couple of days.  Anyone know why this is? There is no logic to it. I've tried all the trouble shooting stuff; the resetting SMC for example. And I've got a surge protector. I've also taken it into an Apple store, a round trip of 3 hours, twice already over the past couple of months.  But after doing some diagnostic tests on it they can find nothing wrong.  Also, when they go to turn it on, it fires up immediately.  I was told that unless they experience the problem themselves they can't do anything.  Which means I'm forever taking it in to them, during this problem, on the off chance it may still be a problem when I get there.  It's very infuriating. Help!!!

    Great advice.  And I'll definitely do that - need to get my Mac back on and working before that however.

  • IMac won't turn on and fans come on right when plugged in

    An iMac I have won't turn on but the fan runs. I don't even have to turn it on, I just plug it in and they go on. When I press the power button nothing, but the fan still runs. I have to unplug it to stop them.
    Does anybody know anything I can try to see if I can get it working again?
    Thanks.

    You may be able to see if the situation changes somewhat by trying a
    reset of the power management unit, via a button hidden in a location
    beneath the iMac (G4) base plate. See info in the following page links:
    • Resetting the iMac (Flat Panel - G4) Power Management Unit (PMU)
    http://support.apple.com/kb/HT1712
    • How to reset PRAM and NVRAM:
    http://docs.info.apple.com/article.html?artnum=2238
    Before attempting to perform either reset, read through each of the
    pages to see what they have in mind; could be a PRAM reset may
    do OK. Or both may lead one to consider entirely different actions.
    If PMU button is held too long an otherwise healthy PRAM battery may
    have a shortened life; or a weak old battery may already be dead. The
    battery (a 1/2AA 3.6V Lithium cell) keeps the system settings current.
    There is a possibility the unit may have some other hardware issues, too.
    Troubleshooting one of these without an official service manual or trained
    iMac G4 technician (is there an antique iMac doctor in the house?) can be
    a tedious process; as the official tech manual will refer to replacement of
    original parts with known-good official ones, as part of an extensive repair.
    After the PMU is reset, perhaps it may boot up; or may boot from an install
    DVD or CD. An original Apple Hardware Test for the computer may be of
    some help in general diagnosis; but even bad hard drives can pass, at times.
    Is there any other indication of the computer trying to run, other than Fan?
    That's hard enough to hear much else inside the case, with the fan running.
    (There is only the single fan in the top of the housing; to pull air up/out.)
    Which specific iMac G4 build version do you have? (700/800/1.0 or 1.25)
    There is an iMac take-apart page, if you decide to go into it for the duration.

  • My Intel imac  won't turn on

    Hi! My intel Imac suddenly, and without apparent reason, shut down, and won't turn back on. When I press the power button, sometimes it makes a small noise, but then nothing happens. I have unplugged all the cables, and also tried resetting the SMC, and still nothing. I see some of you have had a similar problem, I don't know if any of you found out the reason why this happens. The computer is almost brand new (I've had it for 3 months) and up until now I had had no problem with it.
    Thank you!
    Nadia

    You've (unfortunately) joined the growing list of users that are having problems with their iMac. Mine was purchased in September 2007 and I went through two bad ones before I finally kept one until last week.
    Last week: the iMac totally died. It's at the Apple store getting the logic board and PSU replaced. Look through this forum and you'll see a number of other users with random reboots and dead iMacs.

  • My iMac won't turn on, even though it turned on at the store...

    I have a 24" iMac (white), that I bought around 2008. I haven't had any issues with it until recently. It's been really finnicky. At times it would just not turn on, and after waiting patiently for a day or so, it would then turn on. Being too busy to take it in, I ignored the issue. This was a few months ago.
    I recently moved, and I tried to turn it on and it wouldn't. I ignored it for a week and it still wouldn't turn on. I had my brother take it in to see what was wrong and it apparently turned on at the store. I was told that there was nothing actually damaged and it's probably due to me leaving it on sleep mode for extended periods of time and that if it happens again to just leave it unplugged for 24hrs and then try again.
    A week later, my brother brought it back and I had it set back up and yet, IT STILL WON'T TURN ON.
    It hasn't left the box since it left the Apple store.
    I know nothing is wrong with the outlet, because I've plugged other things into it without issue.
    Any ideas?

    Reset the SMC:
    Shut down the computer.
    Unplug the computer's power cord.
    Wait fifteen seconds.
    Attach the computer's power cord.
    Wait five seconds, then press the power button to turn on the computer.
    If that doesn't do anything, you can reset the PRAM, however, that really shouldn't affect power on:
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.

  • Nokia 5800 XpressMusic won't turn on at all after ...

    I've been trying without success to install the new firmware update. I've tried re-installing using the Nokia Software Updater, but kept getting Device Recovery errors and the phone turned off and lost its connection.  After reading other posts, I did a soft reset on my phone then re-installed the firmware without anymore Device Recovery errors.
    However, now the phone WON'T TURN ON AT ALL! When I press and hold the Power On/Off button on the top, it makes a buzzing sound, but the screen stays dark and doesn't turn on.
    Before you ask, the phone battery was fully charged. 
    Help! My 58000 is totally unusuable. How do I get it to power on?

    I had exactly the same problem with my 5800XM.  Twice!
    I have now got the supplier of the phone to send me a new one free of charge, and can only hope that they do so.
    I'd really like to know what might cause such a problem.  Perhaps it was just a faulty phone?  If anyone has any suggestions on what might have caused it, so I can avoid the same thing happening again, I'd be very grateful!  It happened once after I used the mass transfer facility to add music to the phone, and the other time was when I tried reloading the hardware after the shortcut buttons on the home sceen stopped working.
    If thr problem might have been caused by something I'd installed on the memory card, I suppose I'll jut have to start again from scratch, rather than trying to get the files I'd backed up back again...
