IMac G5 Computer Shuts Down Unexpectedly

No unusual circumstances, computer has shut down unexpectedly without warning four times this morning.
Any ideas?

Depending on your exact model, you might be eligible for Rev A repair extension program or Rev B Extension. Check and see if your numbers fall within the appropriate ranges. You can check your model here iMac release dates.

  • Computer shuts down unexpectedly during operations

    My computer shuts down unexpectedly during operations.  The unit will run for about 20 minutes and then suddenly shut down for no apparent reason.  When I try to reboot the machine it comes on and shuts down immediately.  I have to wait 30 minutes to an hour before I can use it again.  I am running windows 2000 as my OS and my motherboard is a K7 prom AMD.  Can anyone out there help me?  I am going crazy trying to figure this thing out.

    Hi, I have the same problem. When windows (XP) starts loading it shuts down and restarts alone; sometimes it passes and loads complete but then after a while it shuts down. With the error free load option it is more stable but it also shuts down alone. I tried everyting that is on my hands: changed the agp to a pci VGA board, eliminated all other boards, flashed the Bios, changed the power supply, checked the Hard Drive, changed RAM, etc., etc. My conclution is that it has some relation with the VGA display but in the bios; if you use more graphics it shuts down.
    My system is a 694D Pro-AR (MS-6321) mother board with Pentium III 1GHz, 768 MB Ram, Matrox G450 Dual AGP.

  • My computer shuts down unexpectedly

    I bought my computer about 2 years a go, its an 13 inch aluminum macbook . In the last two months I have had to repair my UNTITLED DISK due to a "volume issue". In the last 3 weeks my computer shuts down unexpectedly.
    Dont know what to do

    Note the exact time the event occurs, and then check your system logs in your Console application for clues to the cause. You may have a thermal issue. Look for lines with thermal in them.

  • QT opens when computer powers up??  later computer shuts down unexpectedly

    I seem to remember this a while back when I installed a QT update that the computer would shut down unexpectedly and I had to reinstall QT. Does anyone else remember this? Sara

    I just went in and changed to system preference for podcast updates to manual. It doesn't shut down now, but I guess I won't get my podcasts...

  • After installing Maverick on my iMac, the computer shuts down during boot up. Suggestion?

    I installed on an iMac purchased new in January 2013 with full specs, the computer shuts down every time the desktop begins to load.  I've reinstalled Maverick twice from Restore screen, all to no avail.  I don't have any recent Time machine back ups to restore from because of external hard drive failure.  Have a few thousand dollars worth of software on the computer that won't be replaced if not deactivated, so would hate to lose it all, but most of my data is in Drop box. Any suggestions?

    Have you tried booting into the Recovery HD, selecting Disk Utility>Macintosh HD>Repair Disk to see if any repairs are needed.? If anything gets fixed/altered click on repair disk again until you get a clean pass. Restart as normal from the Apple menu. To do this, restart holding down Command + r (more details here: http://support.apple.com/kb/HT4718 ).

  • G5 iMac rev B shuts down unexpectedly

    I know there are other threads on this, but I thought I would start one for G5 iMac rev B models.
    Mine is about 17 months old now (no, I don't have Apple Care!) and has worked very reliably - until yesterday. It shut itself down at some point during the night of Sat/Sun, and again about 5 minutes after I restarted it on Sunday morning.
    What I've done so far:
    1 after the second shut down, I restarted in single-user mode and repaired the disk using fsck -fy. No repairs were reported.
    2 I also repaired permissions, although I believe this is irrelevant to the issue.
    What I haven't done yet:
    3 reset the PRAM
    4 reset the SMU
    So far (touch wood), the computer has not shut itself down again. If it does, I'll do steps 3 and 4 above and post back. It's now had exactly 24 hours uptime, by the way.
    I'm in 10.4.8 (the profile can't be updated, so it's stuck at 10.4.7). Are there any other rev B users who have started to experience these shut downs? Is there any connection to being in 10.4.8, or is that pure coincidence?

    To other Rev B owners with failed power supply units...
    Unfortunately, I was not successful in convincing Apple to cover this part for my son's May 2005 Rev B. The repair was done, out of pocket, for about 200.00, by an Authorized Apple Service Center. I did get a written reply from Customer Relations today to my letter expressing my position and concerns vis a vis others who may be in the same situation. The official response was terse and essentially reiterated Apple's hard line position.
    My guess is that quite a few more Rev B's will have to fail in order for this item to be covered by what would essentially be a revision to the Rev A's Extended Repair Program. The word "current" clearly appears in the original program description on line, as well as in their letter to me.
    In other words, Apple might change course in the future and include certain Rev B models, one would assume, if the failure rates are high enough. At this point in time, it didn't really concern them that 100% of the iMac G5 Rev B's PSU's in our family failed.
    Nevertheless, I understand the company's position. Although my hopes for reimbursement from Apple are dashed on this particular issue, it will not affect my future product purchasing decisions, except that I will definitely get Applecare coverage and insure myself for three years of worry free use.
    It would be interesting to hear if anyone with a Rev B has actually gotten Apple to pay for this repair, outside of an existing Applecare Plan or expired one year standard warranty coverage. I ran into a brick wall, but others may have hopefully gotten through. If so, please share the details of your experience.

  • Just installed Mavericks 10.9.2 on my IMac. Computer shuts down when I leave it unattended instead of going to sleep?, Just installed Mavericks 10.9.2 on my IMac. Computer shuts down when I leave it unattended instead of going to sleep?

    Just installed Mavericks 10.9.2 on Imac and now it wont go to sleep - it shuts down so have to restart repeatedly??

    Because there is a flaw in the App Store that gives you an alert you can never ever get rid of telling you to download Mavericks, even though when you click it then tells you your machine is too (I have to say 'darn' here because Apple automatically astersiks out the first word I used that also begins with d and is four letters) old.  So you have to live with that little  "1 update available" alert, though in reality, you cannot install it. You can imagine that either it is a sinister plot to wear away at you to buy some new hardware, even though yours is working just fine, or that it is a programming error Apple just doesn't care enough about to correct.

I plug it back in to charge it and the battery life says over an hour but before it shut down it said 2 and a half hours. Any ideas?

  • IMac shuts down unexpectedly since Yosemite

    So, I apologize in advance for the long story:
    I have a late-2009 27" iMac i7 with 8gb Ram and a 1TB HD. I updated my OS to Yosemite soon after it came out. Now, I admit I don't use the computer that often, so it took a while to notice the issues but, we first realized there was a problem in early November when my husband could not download a game (presumably because of the wi-if connectivity issues supposedly fixed in the latest update). It was around a week after he finally was able to download tthe game, that he was playing it and the computer would just shut down out of nowhere. No warning, just shut down and restart with the "your computer shut down unexpectedly" screen. Now, because it happened so many times, I started to get worried about all of my photos and music that is stored on thIs computer, so I went to do a back-up on my time capsule. This was when I noticed my computer had at some point been renamed (not by any human) to "my Computer (3)" when prior to yosemite (as far as I can tell) it was named "my computer". Also at this point I could not for the life of me get the time capsule to back up the computer as it was looking for "my computer" and all that was available was "my computer (3)". This is when it had been working flawlessly for years. I ultimately had to wipe the TC completely, reformat it and start a back up from scratch. It was for the short period of time that the time capsule was not connected to the computer that we noticed it was no longer shutting down unexpectedly. however, one the TC was reconnected and doing a back up, anything extra that you would be doing (with the exception of web surfing) caused the computer to crash. So, simple fix, right? Turn off the auto back ups while and try to remember to turn them on every so often. fine , dandy, whatever. However, I have done the latest yosemite update and the wi-if still does not seem to be staying connected, disconnecting every few minutes. Now I'm seemingly having more issues with a game that is well within the limits for my computer and the game will not start. There are just so many things going wrong with the computer that I'm really concerned that everything is going to disappear off of it one day. Anybody have any clues as to my computer's issue??

    Try these in order testing your system after each to see if it's back to normal:
    1. a. Resetting your Mac's PRAM and NVRAM
        b. Intel-based Macs: Resetting the System Management Controller (SMC)
    2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
    4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
                because it is three times faster than wireless.
    5. Reinstall Yosemite from Scratch:
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    How to Clean Install OS X Yosemite
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
                because it is three times faster than wireless.

  • IMac 27" Intel i7 Shuts Down Unexpectedly

    My 18-month old iMac has started shutting down unexpectedly, it will not restart normally, i have to remove & reconnect the power to the machine and then it will restart.
    However it will shut down again soon afterwards.
    It would appear that the longer the machine is disconnected from the power or remains in the off condition the longer it will remain on when restarted.
    Therefore i am assuming this could be heat related?
    Has anyone else experienced this issue?
    What was the reason for failure and who did you resolve?

  • Macpro Shuts Down Unexpectedly

    I upgraded from 10.6.8 this week to 10.8.5 and also installed Pro Tools1 11.  (I have not upgraded to Maverick as Pro Tools dows not officially support it yet.) 
    My machine is a 2 x 2.4GHz Quad Core with 24GB RAM.
    On attempting to open a Logic Pro 9 session and on a separate occasion a Pro Tools 10 session, my computer shuts down unexpectedly and restarts.
    I have copied the crash report below.  Does anyone know what I can do to remedy this?

    Yes you can boot from TimeMachine.
    you can also boot into Recovery Mode, wipe the system, and restore (I prefer to do clean install there instead, and t hen restore). You can also (have not used it) but install Mac OS over the system.
    You can shrink the partition on t he drive with TimeMachine and put a small 25GB system on it, too, handy to boot with that at times.
    It would have been nice to start wtih a new drive for TimeMachine with ML and leave the one you had as is.

    Apple has changed things in 10.9, but making a recovery drive is still possible.
    by Andrew Cunningham - Oct 23 2013, 8:19am CDT  Flickr user Prime Number 
    When Apple released OS X 10.7 two years ago, it stopped selling operating system DVDs in its stores, stopped shipping recovery disks with new Macs, and switched to downloadable installers for OS X upgrades. These download-only installers have actually worked pretty well—I’ve never had an issue downloading the software from the Mac App Store or restoring a Mac using the Internet Recovery feature when something went south. That said, it’s still nice to have an install disk handy for those cases when you don’t have a connection, when your connection is slow, or when you just have a whole bunch of Macs and don’t want to have to download the installer on each and every one of them.
    The good news is, as with Lion and Mountain Lion, it’s possible to create a local USB installer for Mavericks. The bad news is that it wasn’t as simple as it was before—Apple has changed the way the installer works, and making an install disk manually is more difficult than it used to be.
    Before we get started, here’s what you’ll need:
    An 8GB or larger USB flash drive, or an 8GB or larger partition on some other kind of external drive
    The OS X 10.9 Mavericks installer from the Mac App Store in your Applications folder.
    The installer will delete itself when you install the operating system, but it can be re-downloaded if necessary.
    The latest beta of the Lion Diskmaker app, available here (as of this writing, version 3 beta 3 is the most recent). This app is free to download, but the creator accepts donations if you want to support his efforts.
    An administrator account on the Mac you're using to create the disk.
    The easy way
    Lion Diskmaker remains the easiest, most user-friendly way to get this done.
    Andrew Cunningham
    Once you've obtained all of the necessary materials, unzip the Lion Diskmaker app and run it. The app can currently make installers for OS X 10.7, 10.8, and 10.9, but we're only interested in Mavericks today.
    Lion Diskmaker has actually been around since the days of OS X 10.7 (which explains the name), but it's more important now because Apple has made alterations to the installer that prevent the old Disk Utility method from working. It's still possible to create a disk manually using a Terminal command (which we'll go into momentarily), but Lion Diskmaker presents an easy GUI-based way to do it that is less intimidating to most people. One note of caution: Lion Diskmaker no longer supports creating OS X install DVDs. This isn't going to be a problem for any Mac that can actually install Mavericks, but if you'd rather use a disc than a USB drive you're apparently out of luck.
    Anyway, select OS X 10.9 in Lion Diskmaker and the app should automatically find the copy you've downloaded to your Applications folder, but clicking "Use another copy" will let you browse the drive if you happen to have moved it. It will then ask you where you want to copy the files—click "An 8GB USB thumb drive" if you have a single drive to use, or "Another kind of disk" to use a partition on a larger drive or some other kind of external drive. Choose your disk (or partition) from the list that appears, verify that you'd like to have the disk (or partition) erased, and then wait for the files to copy over. The process is outlined in screenshots below.

  • Computer shuts down with charge on battery and no warning

    without warning and plenty of charge on my battery my mac book pro shuts down? if it just sits there in sleep unplugged it seems to run fine, but if its unplugged and i try to use it (with a charged battery) it shuts down with out warning. started about 3 months ago. Is the battery just old..?

    It is almost certainly a sign that your battery is dying, timskins.
    The problem is that when batteries deteriorate their internal resistance increases and they are no longer able to deliver power when it is demanded, even though they still have the ability to store it. They may chug along providing low power for quite a bit longer, but when your computer suddenly needs a bit more (because of increased CPU or GPU demand, or the HD spinning up or whatever) it is unable to provide it and the computer shuts down unexpectedly.
    Think of it like driving a car with a bad fuel pump. Your car is driving along a highway with a full tank of gas. Its running smoothly enough. You put your foot down to accelerate up a hill or overtake a another vehicle and the engine dies because the fuel pump can't meet the greater demand for gas. The tank is still pretty full but the fuel can't be pumped in fast enough to keep it running in a high demand situation, so it shuts down.
    See the section dealing with increasing internal resistance in batteries at http://www.batteryuniversity.com/parttwo-31.htm for more about such things, or http://www.buchmann.ca/Chap9-page1.asp for a longer, more technical, account.
    Once this starts happening the only options are to get a new battery or to avoid any work that makes much demand on power (like visiting a "Flash" based website or, when it gets bad enough, even spinning up the HD from a stationary situation.) Unfortunately even with light use the battery will soon reach a point where the regular peaks of CPU and HD use will become too much for it and you will suffer more and more unexpected shutdowns until the battery is replaced.
    My suggestion would be that you take the battery to an AASP or Apple Store, where they can quickly "stress test" the battery for you to make certain that in your case this is, indeed, the problem.

  • My computer shut down and now my photos are missing

    My computer shut down unexpectedly and now my photo library is empty in iPhoto.  I can't figure out how to recover the photos.

    What version of iPhoto? Assuming 09 or later...
    Option 1
    Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
    If that fails:
    Option 2
    Download iPhoto Library Manager and use its rebuild function. (In Library Manager it's the FIle -> Rebuild command)
    This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
    Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

  • I'm working on my iMac PowerMac8,2 PowerPC G5 (3.1) 2 GHz machine and have been having problems with the computer shutting down unpredictably. After the problem becoming impossible to work with, I shut the machine down. Now a little better, but reoccuring

    I'm working with my iMac PPC G5, PowerMac8,2, 2 GHz machine running OS X 10.4.11, and was having a problem for a while with the machine shutting down unexpectedly. There was no clear pattern to when it was shutting down as far as I could tell. For a while, it would also not restart when buttoned on.
    I set the machine aside for a while, probably a month or more, and then got it back out after its rustication. It started up and runs significantly better than it had been, but I have noticed it shutting down sometimes now again, though not as frequently as before. Sometimes it runs for a good long time between active work, sleep mode, and active work again. Once in a while it does shut down when no one is working on it (while asleep). But now it always restarts when buttoned on.
    I've done the thorough vacuuming of any dust from the unit vents. I wonder if there's anything else I should try. In most other ways the machine works pretty well and has become the family desktop for basic uses, so I'd like to keep it running if I can. A little frustrating to not be able to upgrade all programs (iTunes) to useable versions, but that's another story....
    I would appreciate any ideas about the shut down problem.

    Option 1
    Reset your PRAM.  Press and hold down the Command Option P R keys while starting your computer.  You will hear the startup chime.  continue holding down those keys until you hear the startup chime a second time.  Release the keys.  If the computer restarts, you will need to reset your Date and Time.  It might be time to replace your PRAM battery.  The G5 iMacs require a 3 volt CR2032 lithium watch/camera battery like below:
    http://eshop.macsales.com/item/NewerTech/CR2032/
    You can find these batteries at Walmart, Kmart, Target, most local drugstore chains, for between $3-$5, or at Radio Shack for $12-$20.
    If you have any G5 iMac model EXCEPT the iSight version, you can probably do the battery install yourself.  Watch this video on upgrading your iMac's RAM to show you how to remove the back of your iMac, if you don't already know how:
    http://eshop.macsales.com/installvideos/imac_g5_mem_m/
    While you have the back off, use a can of compressed air to blow the dust out the vents at the bottom of the iMac, the fans, and anywhere else you can.  Also inspect the 28-30 capacitors on the logic board.  Look for dark spots, if they look puffy or swollen, or leaks.
    Option 2
    Reset the SMC by removing all cables (USB, Firewire, Ethernet, Modem, Power cord) from the back of your computer.  Let it sit for one minute.  Press and hold the power on button on the back of the iMac while plugging in the power cord.  Release the power on button.  Count to five, the press the power on button again.
    Option 3
    Place your original, came with the iMac when purchased install disk, into the slot on the iMac, press and hold the C key while pressing the power on button on the back of the computer.  (If you have upgraded your OS from when you purchased your iMac, example your iMac came with OS 10.3 installed, and you're now using OS 10.5, then use the OS 10.5 Retail Install disk that you had used to upgrade your OS instead of the original, came with the iMac disk.) 
    Continue holding the C key until you see the OS starting to load.  DO NOT do an OS installation.  At the top Menu bar, select Utilities or Utility, and pull down to Disk Utility.  On the left side of the window that opens,select your normal OS drive.  Click First Aid at the top middle of the window if it isn't already selected.  Click Repair Disk from the lower right area of the window.  When that is done, click Repair Permissions to the left of the Repair Disk button you clicked earlier.
    When that is done, quit Disk Utility.  From the top Menu bar (I think its under Utilities) select the Start Up Manager, and choose your normal boot volume as the startup disk.  Restart the computer.  If successful, and you've rebooted from your normal startup disk, eject the install DVD/CD, and you're good to go.
    Good luck.
