IMac G5 Freezing problem

Wondering if someone could offer some assistance.
My Mac boots up fine, but immediately freezes (including mouse cursor) once it's at the main screen. After about a minute, the fan gets very loud and there is nothing I can do but hold down the power button to turn the system off.
I tried switching the mouse to a corded non-Mac mouse and it seems to be working ok so far, but I would like to go back to using the original wireless Mac mouse and have my computer not freeze.
Thanks for any advice.

As I mentioned earlier, I had the same problem. By doing the following the problem is now away (already for one week).
Start up and push immediately and together the following 4 keys:
alt
apple
P
R
keep pushing these keys until you hear 3 times the "upstart sound of mac"
shut down the computer
Start the computer again but push now immediately the following 4 keys together:
alt
apple
O
F
You get a screen with tekst
Type now: reset-all
start again as usual without pushing any keys
I hope to be of help. Let me know the result.

  • Imac keeps freezing Problem started with Snow Leopard

    After I loaded in Snow Leopard, my Imac began to have beach balls and freeze ups. Then I loaded in Lion hopeing it would help but it
    seems worse with constant freeze ups. I had the compauter in for a tune up at a Mac store but it was good for a few days, but now
    it seems to happen more often. I dumped Flip for Mac thinking this was causing the conflict to no avail. I have run the utility program
    and it did not come up with problems

    Revert to Snow Leopard and solve your SBBOD issues. Upgrading never fixes underlying issues. See http://www.thexlab.com/faqs/sbbod.html for more details.

  • IMac keeps freezing, needing a restart - Graphics problem

    Hi
    My 2011 21.5 inch iMac keeps freezing.  Strangely, the trackpad works but nothing on the screen reacts to moving the cursor around or clicking anywhere. requiring a restart (using the power button on the back). 
    When I then restart, I get an immediate error message saying "A graphics problem has been detected" and enables me to report the problem, which I do.
    However, this happens several times a day and only since an upgrade to Yosemite and I have tried a software update.
    Anyone have any solutions?
    Many thanks

    Hi Brenden
    Thanks for your suggestions.
    I have been trying to work out, by process of elimination, what the issue could be and it seemed to me that every time I could think of, I had Back To My Mac running. 
    I therefore removed my iCloud account from my iMac and reinstalled iCloud.  Thus far I haven't had a repetition but I am monitoring it very clearly!
    Best

  • IMac freezing problem.

    Hi all, since upgrading to Mountain Lion my iMac keeps freezing every now and then and seems to be getting worse.
    I upgraded to 10.9 Maverick a couple days ago but that didn't help either. 
    Anyone have any ideas what could cause it if it's not the OS?
    My machine specs:

    Guys
    I've had exactly the same issues crashing and freezing all the time... I've determined its OS X Mavericks and how its handling the Comrpessed RAM Its gotta be releated to this its the only explanation...
    http://www.apple.com/uk/osx/advanced-technologies/
    (Make sure you've backed everything up but)... Today to fix my Mac was:
    Run the battery down to zero so it turned itself off. Easily done when installing Ubuntu (Which by the way runs great on Mbp 2010 15") or just leave it turned on doing something. NOT IMPORTANT... I was just being sure all the cached (Compressed RAM) had been cleared from the chips....
    Format the Disk with 1 Partition
    Reinstall with OS X Mountain Lion 10.8.5 fresh from App store download i used Lion Disk maker 2.0.2 to make a installerable USB...
    Check Console for any (FIXME) errors after install ( At nearly a days heavy use now and there isn't a single error in sight...)
    See my screenshot for proof... Not a single Fixme UTF issue in sight on Mountain Lion now... I've done as much testing as i can physically do now im just going to reinstall all my apps are use the system for a month or so unitl they release Mavericks 10.9.2 and see if they have addressed the memory faults...

  • My iMac keeps freezing on me. I don't know what's wrong. I restart comp and within 5min it would freeze. How do I fix this problem?

    While my iMac keeps freezing on me, is there a way I can try backing up my comp as well?

    If you want to preserve the data on the boot drive, and it's not already backed up, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data, you can skip this step.
    There are several ways to back up a Mac that is not fully functional. You need an external hard drive to hold the backup data.
    1. Boot from the Recovery partition or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
    2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

  • Will reinstall of Snow Leopard help iMac stop freezing?

    Hello,
    I've been having problems with my Mac freezing.  I've tried all kinds of things (verify and repair permissions and disk etc, make sure enough free space, as well as checking fans, disk utility etc) and the problem persists.  It's a 24inch iMac that I bought in late 2008 and the problems have been  ongoing intermittently for  months now.  Basically what will happen is  that I’ll be using it when it will suddenly freeze and the screen goes  blank.  The only thing that works then is to restart by holding down the  power button on the back to turn it off and then on again.  I use it  most often for internet (I use firefox) but the issue has happened when  doing other things too, so I don’t think it’s related to any particular  programme.
    I took it into the genius bar and after checking the disks and finding no problem their advice was to reinstall snow leopard.  I was the last appointment of the day before a long weekend and the guy was helpful but fairly rushed.  The thing is that I had this problem with leopard as well before upgrading to snow leopard, so I can't see how it's related to snow leopard.  So, is reinstalling snow leopard likely to help?  Would it be easier to upgrade now to Mountain Lion instead and see if that helps?
    Any suggestions gratefully accepted and please let me know if there's other information that you would need to know in order to provide any suggestions.
    Thanks so much in advance

    I have the same model. What I suggest you try next for this problem:
    1. Run the Apple Hardware Test. It can't detect all hardware problems, especially intermittent ones like you might be having, but it is still a good first step.
    2. Reset the SMC. I'm not sure why but this has fixed some odd problems I have had in the past with my 2008 iMac.
    3. If this doesn't help, try running for a while without any peripherals attached to your iMac besides the keyboard & mouse. If you don't see any freezing problems, try reattaching your other peripherals one by one & running that configuration long enough to see if one of them is causing your problems.
    4. If none of this helps, go ahead & reinstall Snow Leopard, making sure you run Software Update afterwards to update it to the latest version. The Snow Leopard installer isn't like earlier OS installers. To reinstall the system just run it & accept the defaults. It won't write over or alter your user data or create any "Previous System" folder stuff, so it is a fairly painless procedure. It even performs the equivalent of Disk Utility's verify disk step, so you don't have to do that beforehand.
    5. If none of this helps, reply to this topic & we can suggest other things to try.

  • IMAC is freezing and shutting down without explanation

    My IMAC is  freezing and shutting down without explanation . Any thoughts or suggestions?  Could this mean the motherboard is about to die? I have considered erasing the hard drive and reloading, but I'm unsure if that will help i.e. if I back up my IMAC using time machine, then I am just relaoding the problem when I use time machine to reaload........ Thanks!!!

    Disconnect all peripherals from your computer and try -

    You can also cross post over in the Intel iMac area regarding your motherboard concerns.  Users who use the same model computer as yourself would know.

  • Is this the infamous iMac interface freeze?

    I have a brand new Aluminum iMac that's less than a month old. After reading about other new iMac owners experiencing Mac OS freezing on them because of a possible graphics driver issue, I decided not to do the iMac 1.1 update while I was on Tiger. My iMac has been working great with no freezing or lockups.
    After upgrading to Leopard I'm noticing that my machine will not wake from the screensaver properly. I thought at first it might not be waking from sleep, so I turned off automatic sleep, so only the screensaver will come on, and monitor energy save.
    For example, this morning I left the house with the iMac on. 15 minutes later the screen saver came on, then another 15 minutes later, the display was automatically turned off. I came back a couple of hours later and moved the mouse. The display came back on, and I can see the mouse arrow move along with the mouse. The rest is a blank screen. The screensaver (arabesque) isn't showing. I let it sit for 10 minutes with no change.
    I ssh'ed into the iMac and didn't noticed anything out of the ordinary doing a "ps". Nothing was eating up the CPU cycles or taking up unusually large amount of RAM.
    I tried to turn the iMac off by holding down the power button. This actually ended up putting it into sleep mode. When I pressed the power button again, it woke up from its sleep and gave me a login window. I can move my mouse but it doesn't respond to clicks. Also unfortunately I can't type my password. My keyboard is dead. The mouse is connected through the keyboard, and the keyboard's caps lock key responds.
    As a test I tried using VNC to get into the iMac, but unfortunately I can't type my password in that way either.
    I also tried plugging in a different mouse and keyboard at this point, and same problem.
    My only way out is to hold down the power button again to shut it off, and start it back up from scratch.
    Is this the iMac interface freeze people are talking about? Or is this a new problem? Anyone know what's going on? Thanks for your help!

    I should also add that at the time of the freeze, I only had Entourage, Quicksilver, Adobe Illustrator CS3, Adium, and Suitcase Fusion running.
    Also this problem only seems to happen when the machine's idle for several hours. If I try to resume right after the monitor energy saver kicks in, I'm able to revive it.

  • IMac keeps freezing - kernel panics and other

    My iMac keeps freezing on me. Sometimes I get a notice that my computer experience a kernel panic and upon restart have the option of sending the info to Apple, other times it just feezes and I have to do a hard restart but get no prompts about the improper shutdown. This usually happens when I'm working in Adobe Premiere Pro and Adobe After Effects at the same time.
    Am I just overloading the system? And if so, why would it allow me to do that? Shouldn't it just run really slowly or have one application freeze, not the entire system? This hasn't been a problem in the past, it just recently started happening more and more often. Do I need more Ram? That's pretty much the only thing I can upgrade. Here are my system specs, please let me know if you have any suggestions for things I can do to prevent this from happening again. Thank you!

    Thanks for the replies. Baltwo I'll try running those test and see if they find anything.
    Here's a recent Kernel panic log:

  • Late-2009 iMac elusive freezing when uploading video

    Hey All,
    So I am currently experiencing a freezing problem when I try to upload youTube videos through firefox and/or safari after... a checkered past. Hopefully this isn't TMI, just being thurough to save your valuable effort.
    iMac Details:
    21.5-inch, Late 2009
    3.06 GHz Intel Core 2 Duo
    4 GB 1067 MHZ DDR3
    ATI Radeon HD 4670 256 MB
    OS X 10.8.5 (12F45)
    I am using bootCamp with windows 7
         -fyi i did have w7 virtual RAM manually defined (properly or so I thought) and have since reverted to cpu defined vram.
    Funny part is when I was exporting a video from iMovie while simultaniously mixing tracks on virtualDJ while playing a youtube video, everything was fine. Now the history...
    1. Trouble started when I was getting the 'click of death' and the 'beach ball of death' seemingly at random while running various apps one at a time.
         -I reset my PRAM
         -I was and am still totally unable to run AHT (superdrive is dead and all key comands do nothing)
         -I verified disk permissions (there were a lot of errors so I repaired them)
         -I verified the disk (it passed), I repaired the disk even though it didn't need it.
         -I downloaded, installed and ran MemTest. (passed 100%)
         -I determined that I might have a kernal extension problem so I deleted Virtual Box and that seemed to calm things down... for awhile.
    2. So there was peace in the galaxy for a couple months until after running in my windows partition I tried multiple times and could not boot into my OS X partition.
         -I again reset PRAM
         -I again verified and repaired disk permissions (all went fine, tho agian there were many permission errors)
         -I again verified and repaired the disk (even though it passed)
         -I safe booted, it worked
         -I booted into OS X, it worked.
    3. Now, I can restart OS X whenever I want but hard freezing (finder is not responding and refuses to relaunch) still occures when uploading video to youTube having tried multiple browsers.
         -Before when it froze Activity Monitor showed no disk activity, and plenty of realMemory was available.
         -I haven't actaully gotten a read form Activity Monitor when trying to upload. I will tho.
         -I have been unable to find any 'memory leaks' tho I may not understand how to track this
         -My bootcamp partion is totally fine and I've since allowed the CPU to define vram
         -Memtest just now passed all tests.
         -I have had to do hard restart several times while trying different internet browsers.
         -My OS X partition has 344.22 GB free of 1.35 TB.
         -I have no external hardware plugged in, only a USB keyboard and mouse.
    So, a few questions...
         1. Did my manual addition of Virtual RAM on my bootcamp partition mess up my ram? if so why does it still test okay?
         2. Do I have to run memtest as the root user to get a real read on my ram? I haven't done this, yet.
         3. Why do I still get freezes while uploading video even tho when I try to max out my memory usage everything runs fine, no freezing?
         4. Is my hardrive messed even tho it passes checks when I'm booted to an external recovery drive?
         5. Is Apple trying to tell me they want more of the money I don't have anymore because I bought this thing 5 years ago?
    Ya'll are heros for even trying. You knew that. I'm just reminding you.

    So, I've been attempting to solve the issue by using diskUtility to erase free space on my mac and bootcamp partitions to identify bad drive sectors. Unfortunately erasesing free space did not work after defrag on the bootcamp partition. It simply crashed.
    Intitally on the OS X partition I did successfully erase free space and that improved all problems for about 3 days. Then freezes became random and increased in regularity. So I moved about 500GB of data to an external drive (the important stuff) and tried to erase free space again to make it identify bad sectors. So I've tried both booting into my external and recovery drive and having the utility erase free space. Both atempts failed when the utility simply gave up after 2hrs and would no longer recognize the drive. I'm booted into my mac partition right now and am gettimg more random freezing with 2/3 of the drive free.
    I'm resigned to claiming warranty and replacing the drive after upgrading it about 2yrs ago but can't find any real info on what my model and serial number are. All info that I've found does not seem to direct me to the correct information as I've tried entering it into Seagate's website and it will not accept my input. Any advice on claiming on my Seagate warranty and possibly what the model and serial number should look like? I can't seem to find the right numbers.

  • My iMac 24" Freezes constantly

    After upgrading to version 10.4.8 my iMac just freezes in almost every circumstance... this is like working with Windows!!!! What can I do?

    Something may have gone wrong during the upgrade process. I would recommend that you download the "Combo" 10.4.8 update and reinstall it. It seems that using the Combo updater causes fewer problems that the Delta upgrade that appears in your Software Update in the menu.
    Is also a good idea to run repair permissions after an update

  • Why does my iMac keep freezing?

    Problem description:
    21.5 inch Mid 2010 iMac constantly freezes. Problem 1st reported to Apple a couple years ago when computer would freeze, only mouse/pointer would remain active, though clicking did nothing. Now computer works for as little as ½ hour before freezing completely - mouse/keyboard don’t respond, only way out is to hold power button and restart.
    Uninstalled Sophos after reading other posts, still freezes.

  • IMac (still) freezes - console: What is "unknown SIGSEGV code 0" ?

    Some weeks ago I was writing that my iMac started freezing at irregular intervals. At some point I thought that had found the error - unfortunately it still occurs, though.
    Most of the time what happens is this:
    * I draw with my Wacom Intuso 2 in Photoshop CS4. Suddenly nothing works anymore. The mouse Cursor can still be moved (sometimes not even that any more), and iTunes or webradio like Jango still plays what's stored in memory.
    Neither Finder nor the dock, expose or spaces work any more.
    * I can't put the computer in sleep mode. All I can do is force-power-off by holding power for 2 seconds
    * I restart the computer and it works like nothing has happened. Sometimes it stays like that for 15 minutes sometimes I can work several hours or a full day without anything weird happening.
    * there are no graphic glitches so I don't suspect the graphics chip (any more)
    Just to get this out of the way:
    I have an itel Based iMac 24", 3.06GHz DualCore, 2GB RAM.
    It's a work machine: Adobe software, Cinema4D and ZBrush.
    Worked absolutely flawless before. Works stable most of the time on Windows. Crashes are different from those on OSX if they occur though.
    It all started shortly after my mac choked on a security update during install (which had me force-reset the computer the hard way). I installed the Update manually but the freezes still occur.
    I have fixed access-rights (several times).
    I have performed an intensive system check from the OS disc - nothing found.
    I keep the system updated as soon as there are new updates available.
    When monitoring the temperatures the only two values above what I think reasonable at times are Graphics (up to 72°C) and power supply (up to 75°C).
    All other values are well within normal limits. The Mac stands freely and not to close to any wall. No heat source close to it, no window with too much sunlight either ....
    I've already reset the PRAM. No effect.
    Now I'm not too familiar with the console but checking the 'system.log' shows something like this very often:
    * Feb 8 15:59:09 noname kernel[0]: unknown SIGSEGV code 0
    * Feb 8 15:59:39: --- last message repeated 3 times ---
    Is this something that could be crashing my mac?
    Or does this mean nothing, really and the fault still lies somewhere else?
    I'm really helpless, any more. My only hope is that it's no hardware malfunction and that my Mac won't die on me over the next few months.
    Thanks for any help or advice.

    Some discussion and suggestions re. that error can be found in this thread on Adobe's forums:
    http://forums.adobe.com/thread/300392
    Whether or not that will help with your freezing issues I can't say. If not, I've seen anecdotal information that suggests issues with Wacom tablets, but again I can't say with certainty that it involved in your problem, but you might try working for a bit, if you can, with the tablet disconnected and see if that has any effect on the frequency of the freezes.
    Hope this helps.

  • Imac Intermittent Freezing

    Hi
    I hope someone can help as I'm having real problems.
    My Imac keeps freezing, Sometimes after an hour, sometimes a day, sometimes a minute.
    So far to try and rectify it I have:
    Upgraded to 1GB RAM
    Reinstalled Tiger
    Partitioned the drive
    Done Disk Permissions
    Verify Disk
    Disk Repair
    Tech Tool
    Disk Warrior
    Preferential Treatment
    But it still keeps doing it sporadically. When it does freeze it makes a dull clicking, almost spring like sound, from the top right of the dome, quite near the ventilation holes. Its almost the same as the sound made when the machine is switched on. So I'm fearing it may be a hardware problem.
    I can't think of anything else to do as I don't want to take it apart myself. The only thing I might try is looking at these Kernel Panics? and resetting the PRAM? but I don't know much about them. Short of that I may have to take it to a repairer but I want to try and avoid that if I can.
    Any help will be greatly appreciated!!
    Many Thanks!!

    Rumour has it that Mr Totes can now perform this operation inside 30 minutes - But that's another story! :-))) 
    I deny the allegation Your Honour. although.... 
    I concur with you Ian in taking as much time as you need. There are too many fiddly cables in there to rush. Printed instructions are a must.

  • Why does my new iMac keep freezing for no apparent reason?

    Why does my new iMac keep freezing? This usually happens when it is not being used and is particularly frustrating when I do need to use it and ahve to switch off and then on again and wait for it to reboot.
    I am not computer literate so keep any answers as simple and idiot friendly as possible. I treat it like a car. If I put in the key and turn the ignition on and the enginesprings into life I am content. If not.............. well!

    In order to provide any help we need to understand a little bit more about the problem you are experiencing.
    You indicated the issue occurs when the sytem is not being used. Does this mean that you stop working on the system and the system 'goes to sleep' where the screen goes black, but when you need to wake it back up by pressing keys on the keyboard or clicking the mouse the system doesn't wake back up? To test for this issue open the System Preferences and click on the Energy Saver preferences. See the 'Computer Sleep' slider to the far right 'Never' setting. You can set the 'Display sleep' setting to any number you prefer. With these settings see if the issue still occurs and let us know the results. If it resolves the issue then give Apple a call and let them know you are unable to wake the system when it goes to sleep. You shouldn't be having that issue.

Maybe you are looking for
