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.

  • TS3276 I recently installed LION and have been having email problems, sending and receiving since. My server (Cable-fiber optics) tell me they see nothing wrong, that it is a program issue. I get messages about not recognizing the certificate.

    If I click the go-ahead button, I am warned about not be assured of security danger. This keep happening over and over. It is a pain using email since LION. I went into Keychain Access and tried choosing an Apple certificate, but that is never permanent. Should I just ignore the warning? Will this kind of problem disappear with Mountain Lion? Is there a solution?

    What email program are you using?

  • I am and have been having major problems with my G4

    I am hoping someone can help me solve these problems.
    Issues I am having with my machine:
    1. No sound in the speakers.
    2. Red light in audio jack.
    3. Very slow performance.
    4. Extremely long start-up time for both system and applications.
    5. Fuzzy monitor.
    6. Monitor clear on the left side, fuzzy on the right.
    7. When applications are running, very slow response time when changing from one tool to the other.
    8. Most Adobe products do not respond upon start-up or shut-down.
    9. Machine locks up, stopping clock, force quit, or any other function I am trying to perform.
    10. The machine never behaves the same way twice in regard to start-up shut-down, etc.
    The performance and functionality of my machine has become progressively worse. Can anyone offer any suggestions or tips? I see there are many discussions on related topics. My machine has multiple problems and I would like to remedy as many as I possibly can.
    Thank you.

    my  ipad i have been restore it yesterday my computer shut down in the middel now my ipad2 stuck in recovery mode and cant be detect by itunes and it is jaikbroken ?

    Try these steps. If it doesn't work the first time, try a second time.
    Disconnect the USB cable from the iPhone, iPad, or iPod touch, but leave the other end of the cable connected to your computer's USB port.
    Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the device to turn off. (If you cannot turn off the device using the slider, press and hold the Sleep/Wake and Home buttons at the same time. When the device turns off, release the Sleep/Wake and Home buttons.)
    While pressing and holding the Home button, reconnect the USB cable to the device. The device should turn on. (Note: If you see the screen that shows you are out of battery, let the device charge for at least ten minutes to ensure that the battery has some charge, and then start with step 2 again.)
    Continue holding the Home button until you see the "Connect to iTunes" screen. When this screen appears you can release the Home button
    If necessary, open iTunes. You should see the following "recovery mode" alert: "iTunes has detected an iPhone in recovery mode..."
    Use iTunes to restore the device.
    If you don't see the "Connect to iTunes" screen, try these steps again. If you see the "Connect to iTunes" screen but the device does not appear in iTunes, see this article and its related links. http://support.apple.com/kb/TS1538
    Hope this helps!

    I have been having a issue with getting the colors on my monitor to match the colors fro my print lab. I now have the monitor calibrated to match the prints but when I open elements it doesn't use the same colors. If i have it use the calibrated profile by changing the color management settings, the color picker no longer shows true white or black. How do I get elements 12 to honor the new calibrated settings?

    Ok so I've done what you said and this is what it's come back ....
    I don't know that these are the errors , but they're the things which don't look right ...
    Throughout the shut down there is a recurring line ;
    It says ;
    Com.apple.launchd 1 0x100600e70.anonymous.unmount 301 PID still valid
    Then there are 2 more which I think are related ;
    Com.apple.securityd 29 PID job has I overstayed its welcome , forcing removal.
    Then the same with fseventd 48 and diskarbitrationd 13
    Oh and on Launchd1 : System : stray anonymous job at shut down : PID 301 PPID13 PGID 13 unmount...
    Then the last process says "about to call: reboot (RB_AUTOBOOT).
    Continuing...
    And stops ...
    Hope this means something to you ... Thanks again for your help so far :-)

  • Since downloading OS X Yosemite I have been having issues with Netflix. Video slows down which causes the audio to go out of sync. Netflix plays ok on ipad which makes me think it's the software which is the issue. Has anyone else had this issue?

    Try this:
    Go to System Preferences - Bluetooth. Delete the keyboard from the list of devices by pressing the "-" button. Take the batteries out of the keyboard and reinsert them. In Bluetooth Preferences press the '+" button to add the new device. If the keyboard begins to pair, click the word "pair" and type in the passcode. Press return. The keyboard is now paired.
    If the mouse is not pairing, try this: shut down the computer completely, unplug any USB mice, then turn off the power to the bluetooth mouse.  ONce the computer starts up again, wait for the pop-up looking for a mouse.  Turn on the power to the bluetooth mouse.  It should work normally now.

  • I have just upgraded to Mavericks and have been using Time Machine on an external disk with Snow Leopard.  Can I continue to backup with Time Machine on the same external disk or do I need a new disk since the operating system has changed?

    Hi there,
    I found that Time Machine in Mavericks will sort it all out for you. You shouldn't need to buy another backup drive, unless you have insufficient space left and can't afford to delete whats on there. It should just work fine.

  • I have a nook and have been using it regularly to borrow library books along with digital editions.  Normally as soon as I plug my nook in the icon pops up on the desk top.  Now it doesn't and it isn't showing up in the digital editions.

    I have a nook and have been using it for almost 8 months to borrow books from the library.  Normally, as soon as I plug in my nook, the nook icon pops up on the desktop and digital editions recognizes the nook.  All of sudden the nook icon is missing and If I try to unplug from the computer, it says it was not disconnect properly.  Any ideas?  Is something hidden or what?

    I'm just trying to print my online pay stub
    Since my printer isn't working, I'd like to save document to my desktop ("save as" is the only option given to me) and send it as an attachment to a friend's computer and working printer.
    What browser are you using?
    Are you trying to print or to save the doc? Whether you have a working printer or not is really immaterial. If you're trying to print, then File > Print > PDF > Save as PDF…. If the resulting PDF is small enough (<5MB, though my preference is <1MB), e-mail it to your pal. If it's too big, transfer it using a chat programme or a file service (MediaFire, RapidShare, etc).
    Now, I am currently trying to send the document directly (via email, an option given under "file") the pay stub from my employer (who uses ADP online payroll services), to that computer and working printer ....and I'm receiving a window (with apple mail logo on it) that begins with  "To view this page, you must log in to this area on agateway.adp.com:443:"  and asks for "name" and "password".  I've put in both ADP's information, and what I believe (could be very wrong) to be apple mail's information, and either/neither/nothing seems to work!
    I don't understand any of this. You need to explain better—or perhaps just post a screen shot (blank any private or confidential info on it prior to posting).

    Sorry to say but your imac g5 logic board has bad caps. This was a problem apple had and issued a out of warentee fix but that has now expired.
    The cost to get this repaired is more than what you could find another used imac for.
    I would suggest you get some details before you rush to make a diagnosis. You have absolutely no information to base this on. I see you're hitting up on numerous threads all over the place. Quality, meaning several good posts with reliable advice, is much more worthwhile than quantity.

  • I have been having a lot of trouble with the latest itunes update and my ipod classic 80Gb i.e. being unable to sync songs, but now i have no files at all on my ipod, it is completely blank when i view it from my computer. I need help, please, anybody.

    As it says above, i have been having a lot f trouble with my ipod classic and the latest itunes update, i was unable to sync songs or anything to it and have tried every conceivable 'fix' i could find. i have run an itunes diagnostic and the results are posted below. a major problem is that when i try and view my ipod through my computer it displays nothing at all on the ipod, no files or anything, this may be the problem but i have no idea how it has happened or how i could resolve it.
    This ipod holds huge sentimental value and i am loathe to buy a new one! If anybody can help it is greatly appreciated, than kyou in advanced.

  • I downloaded the latest version of Pages 5.0 and have been using it for days.  Now, when I try to open documents created with this version, I'm advised that I need latest version of Pages to open.  What's going on?

    First time user.  Need help.  I downloaded latest version of Pages 5.0 and have been using it.  Now, when I try to open documents created by it, I'm advised that I have to downoad Pages 5.0.  What's going on?

    You have 2 versions of Pages on your Mac.
    Pages 5.2.2 is in your Applications folder.
    Pages '09/'08 is in your Applications/iWork folder.
    You are alternately opening the wrong versions.
    Pages '09/'08 can not open Pages 5 files and you will get the warning that you need a newer version.
    Pages 5.2 can open Pages '09 files but may damage/alter them. It can not open Pages '08 files at all.
    Older versions of Pages 5 can not open files from later versions of Pages 5.
    Once opened and saved in Pages 5 the Pages '09 files can not be opened in Pages '09.
    Anything that is saved to iCloud and opened in a newer version of Pages is also converted to Pages 5 files.
    All Pages files no matter what version and incompatibility have the same extension .pages.
    Pages 5 files are now only compatible with themselves on a very restricted set of hardware, software and Operating Systems and will not transfer correctly on any other server software than iCloud.
    Apple has removed over 110 features from Pages 5 and added many bugs:

    You can add the icon of the missing Pages on your Dock or open Pages from the Apple menu > Recent Items list.
    Or you can archive Pages 5 so that it doesn't automatically open.
    If you are unhappy about this review/rate Pages 5 in the App Store.

  • I have an iMac with Mavericks that is experiencing a lot of "spinning balls" from particularly Mail, Google Chrome, and Word. I took it to the Apple store and it was fast there, at home slow. I have been having internet speed issues, could it be that?

    I have a pretty new iMac with LOTS of storage (about 4TB with externals) that is experiencing a lot of "spinning balls of death" from time to time in almost any program that I might have open, but particularly MacMail, Google Chrome browsers, and Word. I took it to the Apple store to be checked out and it was really fast with no issues there. I brought it home and it was better at first but then it started happening again.
    I have been having a lot of issues with Time Warner where my download speeds will dip really low, and all I can think of is that MacMail goes and tries to check for email and can't get out to the internet and it locks all the other resources up while it is doing it. It will also take a REALLY long time to even let you look at mail. The folder size is over 13GB (down from 22GB that I just cleared out from - I have a lot of MP3s etc in there) and I will try to get this down to under 10GB which might help, and the mail is on an external drive. I have been told that Verizon is not a shared network but a direct connection to their server, and if I can't fix this then I will try switching to them. If anyone has any direct knowledge on this stuff, I am all ears.

    We need to know more about your system, please download EtreCheck and run the report and please post it on your next reply. Then we can see how your system is configured, what apps are on it and look for anything obvious. We will look forward to seeing your report.
