IMac suddenly reboots

Hi,
Last month I bought a new iMac (27inch i7 processor and 8gb ram), and after an hour or four it suddenly rebooted every ten minutes or so. I brought it back to the official reseller so they would fix it, I got my iMac back and after a few hours it started happening again! So I brought it back again, they said they didn't know what caused the problem and would try to fix it again, they tried replacing to power supply to the hard disk. But this didn't change a thing so I brought it back again.. I asked if they were able to give me a new iMac, they said they were not allowed by Apple.
Anyone experienced the same issues or has a solution?
I changed to Apple as I thought they would offer better quality, turns out I only have problems with it. (sorry for my crappy English, I'm Belgian)
Kind Regards,

Well, when it happens to you, then it is not an extremely uncommon one. I am not a mac novice, far from it having bought macs since day 1, but this is the first time I am facing this spontaneous rebooting.
This does not happen to my other imac which is standing next to this. My take on this is that it has something to do with Snow Leopard. The other imac 24" is still running on leopard. I have done research on this and this problem is fairly common, sometimes running under the thread: spontaneous reboots under Snow Leopard.
What's infuriating is that the reboots just happens very randomly; there are no set pattern. Poofs, the screen goes black and then restarts. I have switched off every startup program that might cause the problem but to no avail.
But currently I might have found the solution. The 27" imac works pretty well for the first few months before the problems started recently. I happened to read one thread that temperature might be the problem. I downloaded Temperature Monitor and found out that the gpu temperatures were touching 70C and cpu temperatures were nearing 60C. So next I downloaded smc fan control and bump up the fan speeds. GPU are now down to 62C and CPU to 48C. So far no reboots. Touch wood.
I sincerely hope that this is the cause of the problems but I will update once I test this out longer. BTW my machines run 24/7 everyday. Others being 2 other minis and a G5 tower. My guess is that dust buildup over time might have exacerbated the heat problem and coupled that with the heat spell we are having at the moment. The reasons why the macs are not affected could be that SL has lower thresholds. I have my Macbook battery died on me right after I installed Snow Leopard but that is another story. My ancient iBook battery is still running fine! Go figure.

  • IMac suddenly reboots and most app quit functioning properly

    Hi,
    i think I can link the following to updating Skype to the latest. After install, iMac rebooted abnormally with problem reporting window. It actually rebooted at leaat ten times in a row. Even when I wanted to shutdown it would reboot (thus restart on its own). Then I realized that Twitter would open an problem reporting window but would not start. Same for Thunderbird. iTunes re-initialized with no content. I then started adding some album to library and stopped after some ten albums. I quit-ed it, renamed the iTunes folder (where the library xml sits) and restarted iTunes with the ten albums still there. Then added the library xml as playlist which it digested but still not recreating the iTunes folder at its original place. Where is it? iPhoto asked to repair the library but got stuck in the middle of the process. No idea whether I would loose photos. I am completely puzzled by the behavior. What could have gone wrong? Is that a virus?
    My configuration includes an SSD (with OSX Yosemite and Apps) and an HD (for data). I have been backing up on a Time machine. Can I re-image the machine as it was, i.e. SSD and HD, automatically from the Time machine? What is the process?
    Thanks for your help.

    Thanks Linc. There are loads of entries in the left tree. A lot of .diag, .crash and some .awd.
    Below I list the panic report I had saved yesterday (though I do not see it in the "DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports" list) as well as the first .crash I see at the bottom of the list. I wanted to list all files via Terminal but Terminal refuses to launch.
    I shall launch in safe mode.

  • IMac suddenly chimes, and reboots itself repeatedly

    can anyone help? My early 2008 iMac suddenly reboots itself, chimes, but then screen does not come on. I can hear the disk spinning, but no video, and the mouse and keyboard dont have any effect.
    Afetr a while, it suddenly responds to the power button, and then reboots itself randomly. Been happening randomly now for long, and its driving me crazy!!
    Any idears anyone please.....??

    Try using Apple Hardware Test on your iMac it sounds like a video or RAM problem. 

  • My iMac suddenly started running slow. almost every action invokes the color wheel

    my imac suddenly started acting very choppy.  streaming internet music works normal. every action requires a delayed response. sometimes 30 sec before it starts the command. i have not downloaded any programs in months. my imac is running OS x 10.8.2 with 4GB ram.my HDD has 65Gb free space. ext HDD has 248GB free space. i do not use any virus programs.

    Hello, see how many of these you can answer...
    See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...
    http://support.apple.com/kb/PH7029
    Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
    Open Console in Utilities & see if there are any clues or repeating messages when this happens.
    In the Memory tab of Activity Monitor, are there a lot of Pageouts?
    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
    Reboot, test again.
    If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
    Check the System Preferences>Other Row, for 3rd party Pref Panes.
    Also look in these if they exist, some are invisible...

  • IMacs suddenly shuts down

    Hi,
    Since a while my iMac suddenly shuts down and reboots.
    It starts with a frame freeze, can't move the mouse cursor. After a few seconds my iMac shuts down.
    I have no idea what the problem can be.
    This is the report of Console when it shuts down.

    Hey MagicMarcus,
    Thanks for the question. I understand that you are experiencing issues with your iMac unexpectedly shutting down or restarting. The following resource provides some great information if this happens, along with potential resolution steps if it is a reoccurring issue:
    OS X: When your computer spontaneously restarts or displays "Your computer restarted because of a problem." - Apple Support
    http://support.apple.com/en-us/HT200553
    Thanks,
    Matt M.

  • IMac suddenly shows white screen after update Yosemite to 10.10.1

    The day after I installed the update(10.10.1) for Yosemite, regularly my iMac suddenly stops working by showing a white screen. After 10 seconds, the iMac reboots automatically and again shows a white screen. Than, it stops. No action. No noise. I'm  always obliged to stop the iMac by pressing the start button and restarting by holding the 'shift' key otherwise I have to look at a white screen again! In the save modus, I can work(typing this story) and restart the iMac. After a while, the whole show starts again. What can I do? Installing Yosemite again and whiteout the update? Can I undo the update? This once, I made no backup before the update(Murphy's law). Any suggestion will do!

    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 suddenly keeps restarting with no warning!?

    So last week my 27" iMac suddenly starts rebooting with no warning. Very frustrating. Have zapped PRAM and reset SMU... still happening. Can't track it to anything repeatable when it happens... any program, any time. Happens randomly... some days 3-4 times, some days 1. Have 4 GB of DDR2 SDRAM installed, but running full CS suite daily... perhaps bad RAM. Can it go bad? It's been fine for well over a year since new and it's been my experience that if RAM is bad, it's bad right away.
    Should mention that I'm a daily Mac user for 20+ yrs (designer) and feel fairly comfortable diagnosing and solving any issues, but this one has me stumped.

    I'm not sure about the original poster's "graphite" iMac, but if your "2nd gen" iMac refers to a "tray-loader" (CD goes in on a tray not a slot), you probably have the same problem I had... Later slot-loader iMacs many have similar problems, but I don't have first hand experience with them.
    The most likely cause of the problem is a bad analog video board, specifically the part on it called the "flyback transformer." Do and Google search on "analog video flyback imac" and you should see some useful results.
    When my iMac's board went bad, it stated to shut off for no reason. Eventually, it would not even start up. Actually, one other symptom is a "sparking" noise and momentary "jerking" of the screen image. For me, this started happening a few months before the shut off problem started. Unfortunately, replacing the part is somewhat difficult (requires almost full disassembly), and since you would likely be replacing the bad part with a used part from eBay, the replacement is likely to fail too. This is a very common "first failure" for these old iMacs. I think the iMac is designed to shut off or not turn on as a safety feature when the video board is bad. However, if you disconnect the internal video cable (you may have seen it when you upgraded memory), it may start up.
    I turned my broken iMac into a "headless" machine by pulling out and reassembling the essential "non-CRT-related" parts on a shelf, connected to and above a very nice 19-inch CRT display (1280x960 at millions of colors). I'm using it now, and it works very well (Mac OS X 10.3.9).

    That panic was not caused by third-party software. If the problem is recurrent, the possibilities are:
    A stale or corrupt kernel cache
    A damaged OS X installation
    A fault in a peripheral device, if any
    Corrupt non-volatile memory (NVRAM)
    An internal hardware fault (including incompatible memory)
    An obscure bug in OS X
    You may already have ruled out some of these.
    Rule out #1 by booting in safe mode and then rebooting as usual. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
    You can rule out #2 and #3 by reinstalling the OS and testing with non-essential peripherals disconnected and aftermarket expansion cards removed, if applicable. Sometimes a clean reinstallation (after erasing the startup volume) may solve a problem that isn't solved by reinstalling in place, without erasing.
    Corrupt NVRAM, which rarely causes panics, can be ruled out by resetting it.
    If your model has user-replaceable memory, and you've upgraded the memory modules, reinstall the original memory and see whether there's any improvement. Be careful not to touch the gold contacts. Clean them with a mild solvent such as rubbing alcohol. Aftermarket memory must exactly match the technical specifications for your model. Memory that is either slower or faster than specified may be incompatible.
    The Apple Hardware Test or Apple Diagnostics, though generally unreliable, will sometimes detect a fault. A negative test can't be depended on. Run the extended version of the test.
    In the category of obscure bugs, reports suggest that FileVault may trigger kernel traps under some unknown conditions. Most, though not all, of these reports seem to involve booting from an aftermarket SSD. If those conditions apply to you, try deactivating FileVault.
    Connecting more than one display is another reported trigger for OS X bugs.
    If your system is not fully up to date, running Software Update might get you a bug fix.
    In rare cases, a malformed network packet from a defective router or other network device can cause panics. Such packets could also be sent deliberately by a skillful attacker. This possibility is something to consider if you run a public server that might be the target of such an attack.
    If none of the above applies, make a "Genius" appointment at an Apple Store to have the machine tested. You may have to leave it there for several days. There isn't much point in doing this unless you can reproduce the panic, or if you can't, it happens often enough that it's likely to be repeated at the store. Otherwise you may be told that nothing is wrong.
    Print the first page of the panic report and bring it with you.
    Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you know how to restore, and you have at least  two independent backups.) Don’t erase the recovery partition, if present.
    Keeping your confidential data secure during hardware repair
    *An SSD doesn't need to be zeroed.

  • Can anyone help me get my iMac to reboot?  I get a gray "curtain" over the start up screen saying I need to restart my computer but it won't restart.  I just keep getting the same message every time.

    Can anyone help me get my iMac to reboot?  I get a gray "curtain" over the light gray start up screen with a message that I need to restart my computer and to hold the power button until it powers off and then press the power button again to restart.  It just does this over and over again and won't restart.

    Yeah, as necronym stated, it is a hardware issue and more than likely a RAM problem. Disconnect everything from the computer except keyboard and mouse and try again. If it still happens try removing one and/or swapping your RAM sticks over. Keep trying until you have eliminated all possible combinations. Just put a mark on one RAM stick so you know what have tried. If it still fails to boot properly you should probably replace your RAM, but that is no guarantee of success. Have a look at this link for more info on a Kernel Panic.
    The X-Lab - http://www.thexlab.com/faqs/kernelpanics.html
    Does the display look like this?

  • My iMac suddenly no longer connects to wifi network when in KIOSK (username) mode, and only connects when as ADMINISTRATOR mode. Its strange because the iMac has been working fine in KIOSK mode for over a year until 2 days ago.

    My iMac suddenly no longer connects to wifi network when in KIOSK (username) mode, and only connects when as ADMINISTRATOR mode. Its strange because the iMac has been working fine in KIOSK mode for over a year until 2 days ago.

    One of the memory cards was indeed faulty, and the other completely fine
    Thanks very much for all your help!
    Although there is one little thing that I've noticed. The iMac works properly, but I tried to software update to see if that may help my Minecraft sound issue (as I still don't think only having 2GB instead of 4GB would cause such a problem) but the software update application won't work. Running the "Software Update" from the apple menu on the toolbar gains no response, nothing happens. If I run the software update from  system preferences, the application icon appears for a second, then disappears (as in the blank app. icon, the blank canvas with the pencil, pen and ruler in the bottom right corner). It does this every time I try to run it. It did work when the computer was crashing, but this started when on one of the occasions I ran the app. while it was crashing. Since this occured during the crashes, and still occurs now, I'm wondering did something simlar happen minecraft, as it's sound disappeared during the crashes and is still gone now.
    However, the computer is now working again without crashes, which is the main thing, thanks for helping me fix the issue
    Edit: I would mark the topic as solved, but I'm unsure if this would lock the topic or something simlar, so I'd rather leave it open for any ideas regarding the software update and Minecraft issues I'm having

  • What is this? iMac i7 reboots on its own.

    Can someone tell me if this is a memory issue? iMac i7 reboots on it own...

    which is basically disconnecting ALL cables and power, and reconnecting following a precise procedure. When you reconnect it, initially try running the iMac with just your keyboard/mouse connected (nothing else). Check to see if this problem recurs.
    If it does not, reconnect your other peripheral devices one by one, and keep checking if the problem recurs. If it does a some point, backtrack to identify the device added last. It may be faulty or interfering with the iMac.
    If the problem recurs, even after the SMC reset with just the keyboard/mouse connected, please post back.

  • My iMac suddenly can't read the backup hard drive I've been using for Time Machine.  I did NOT just upgrade the OS or anything.  The external HD is an OWC Mercury Elite All Pro. It's worked fine since I got the iMac 4 years ago.`

    My iMac suddenly can't read the backup hard drive I've been using for Time Machine.  I tried unplugging the cord that connects the HD to the iMac and plugging it back in, but I still get "The disk you inserted was not readable by this computer" below which are buttons for Initialize, Ignore and Eject.  I was using a cord that went from larger square plug to larger square plug.  So then I tried one that went from smaller square plug to what I think is USB (thin rectangular plug) of the sort that connects the keyboard and mouse. It's the type that my printers and scanners use to connect to the iMac.  I did NOT just upgrade the OS or anything.  The external HD is an OWC Mercury Elite All Pro. It's worked fine since I got the iMac 4 years ago. What else can I try before just trying to initialize and

    Thanks, Michael!  I do hear it at times spooling up and running. Just after I bumped the thread I looked for troubleshooting for this drive online and found the manual which suggested using Disk Utility which I've seen before accidentally (if I hit Command Shift U instead of Shift U to type "Unit" on a new folder for a student's homework ) but had never really noticed.   Disk Utility does see it and also a sub-something (directory?) which might be the Time Machine archives on the disk, called disk1s2), sort of the way that my iMac's hard drive shows up as 640.14 GB Nitachi HDT7... and has a sub-something titled DB iMac, which is what I named my iMac's hard drive.
    Anyway the owner's manual just shows the image under the formatting section, not the troubleshooting section, but as soon as I saw it in the manual I remembered seeing it accidentally a few times, went to it, and am now verifying the disk.  Right now it's telling me that it will take 2 hours to complete the verification, so I guess I have a bigt of a wait.  :-) 
    Does that fact that Disk Utilities can see it mean it's not failed, or just that it hasn't completely failed? 
    I can see the virtue in having multiple redundant backups, or at least two backups. What do you suggest?  Two external hard drives?  I had this one linked by ethernet, and but I also have a cord that could link it by USB (like a printer), so if this one is reparable I could get a second one and link it by USB.  If this one is not reparable I could get two and do the same thing.  I do have an Airport so I suppose it's possible to get some sort of Wi-Fi hard drive (my new printer/scanner uses only the network and not a cable, although it has a cable that I used for the initial installation), but I'd suspect a Wi-Fi hard drive might have a higher price.
    What hard drives, if any, do you recommend? I seem to recall that when I was looking at external hard drives 4 years ago, Apple's were substantially more expensive, which is why I got the OWC Mercury Elite All Pro.

  • IMac suddenly can't connect to wireless!

    My iMac suddenly refuses to connect to wireless! It worked fine before.
    Tried everything including resetting the wireless router.
    It always said that my password is invalid... My password is correct!
    Can anybody help me? Thanks!

    I'm having the same problem.  I have a time machine that I use for my wireless router.  I connect wirelessly using my Macbook Air.  It has worked fine for months.  Today, about 4 hours ago, my wireless connection stopped working.  When I connect via ethernet directly, it works.  I know it's not my router, because I also tried a spare Airport Express and that doesn't work either.  I'm going to try restoring the time machine to its factory settings and configure it from scratch to see if that works.  I'll post back with the results.

  • Sudden Reboot in 10.6

    Ok there people,
    I have had the strangest thing happen after I "upgraded" to 10.6. It has happened a couple of times now and I was wondering if anybody has had the same issue I have.
    I start up Quicktime 10 I start to play a movie it runs for maybe 2 to 10 seconds then I press cmd -f for full screen and Boom instant reboot. Screen turns black and well you no how a reboot goes.
    I can't seem to find a common ground for this issue other than the fact that I'm trying to get a movie to play full screen. It won't happen for like 30 times but than out of the blue.
    I say mystery dear Watson, what do you guys think.
    Message was edited by: TPA8580

    I'm glad to see I'm not the only one having the same exact problem, I thought my Mac mini had an hardware problem.
    I've had two of these "sudden reboot" since upgrading to Snow Leopard, I never had them before. In my case it happened after a mouse click: the screen froze for 2 seconds, then I got a blue screen and a "reboot".
    These reboots seem quicker than normal reboots.
    Looking at the console, it seems that the reboot occurred because the WindowServer crashed.
    9/25/09 2:51:05 AM iTunes[28762] HIToolbox: received notification of WindowServer event port death.
    9/25/09 2:51:05 AM com.apple.launchd[1] (com.apple.WindowServer[90]) Job appears to have crashed: Segmentation fault
    I did some research about the message "WindowServer event port death" and found that it was linked to sudden reboots that also happened for some users in Leopard (10.5).
    Another thing I found is that other users have been experiencing "sudden log-outs" when the WindowServer process crashed. Since I have auto-login on my Mac, I suspect that what we've been experiencing are not "sudden reboots", but rather "sudden log-outs" where the OS suddenly logs out and then automatically logs-in.
    I'm running 10.6.1... I hope this is going to be fixed with 10.6.2 because it's extremely annoying.

  • I downloaded carbon copy. transferred entire internal hd  to new replacement HD  thru USB.  computer booted from replacement hrdrive. then installed replacement hard rive into iMac. when rebooting imac did not recognized new replacement hd.

      i downloaded carbon copy. transferred entire internal hd  to new replacement HD  thru USB adapter kit.  computer booted from replacement hrdrive. then i erased the internal hardrive and reloaded the operating system.( i needed to find out if the hard drive was bad or virus/worm was the cause). then installed replacement hard drive into iMac. when rebooting, imac did not recognized new replacement hd. i also upgraded memory at the same time.  ok what did i do wrong. do i have to remove the new replacement hardrive to extract the data.

    It should not matter. CCC will "clone" the recovery partition as well, but not knowing exactly what operation you had CCC perform it is difficult to know what may have gone wrong - it has many customizable options and you have to choose the correct one.
    I have performed the same transplant as you described and didn't have a problem, but if your Mac is not recognizing the internal HD you really have no choice other than to reinitialize it as suggested. After that, install OS X, upgrade to Mountain Lion if required, and migrate your old account(s) from your backup.
    my backups have backups.
    I assume you didn't mean that literally. Have redundant backups - don't "back up your backups".
