Imac random shutdown prugatory... please lend an ear!
what a terribly frustrating situation. here is my scenario:
bought a new intel core2 duo imac in september of 2006 and after a year i was forced to upgrade to leopard and install windows xp using bootcamp in order to do work on the machine (to pay bills which is why i say "forced")
in hindsight it seems as though the computer may have been randomly shutting down as i was using windows however if it was, the computer was restarting to a fresh boot of windows.
so after a year and a bit i can finally replace the imac and buy a real windows only pc for work, which means i can use my mac again (yay!)
first problem i have to solve is the fact that it overheats the ati video card and i installed smcfancontrol to stop the overheating...
but now the computer restarts... aaaaalllll the time.
i dont have any third party things running other than:
-smcfancontrol
-google notifier
-connect 360 (xbox 360 media extender for mac
i went ahead and unplugged all the cables and let the computer sit OFF for 30 minutes (15 minutes is what apple says is the minimum) which is supposed to reset the PMU and this does not help either.
One thing that is curious is that the power management is set to NEVER turn off the monitor however it always turns it off.
The computer is set to never hibernate and it doesn't... but the screen always goes off.
i had screen saver set to OFF and it always went on. Now i dont see the screen saver anymore so i guess that is working.
Seems to me this is a hardware issue?
The machine is way out of warranty and there is no apple care... so what could this be?
Apple's repetitive response of "replace the logic board" is what the genius bar guy told me when i was getting my iphone replaced and that just scares me.
it is always the logic board.
and so i ask here for HELP...
thanks.
If you haven't tried this, reset the System Management Controller. Instructions here:
http://support.apple.com/kb/HT1543
*"Seems to me this is a hardware issue?"*
Run the Apple Hardware Test from the restore disk(s) that came with your iMac. Go here for instructions.
http://www.tuaw.com/2008/08/01/mac-101-running-the-apple-hardware-test-software/
Have you checked the boot disk for errors? Restart your Mac while holding down the C key, pressing the power button and inserting your restore disk all at the same time. An Installer window will open, but do not proceed with any installations. Instead, from the Menu Bar, select Utilities > Disk Utility. In the Disk Utility window click First Aid, and then click Verify. If Disk Utility reports errors, click Repair. While you are running Disk Utility, at the bottom of the window where you see: S.M.A.R.T make certain it says: Verified. When Disk Utility you are finished with the Disk Utility application, from the Menu Bar, select Utilities/Startup Disk. Select MacintoshHD 10.x.x and click Restart.
The S.M.A.R.T is a monitoring system to detect possible hard disk failures.

Imac G3 500mhz
It will power up and run fine and then will shutdown and the power light pulses slightly, can hear a slight buzz from the power supply/monitor part of the Imac, changed motherboards and downconverter and still the same problem. Possible bad power supply? Can unplug system and let it sit and then plug back in and it will start up and then shutdown again. Any help would be nice, ThanksIt is most likely (and obviously) a hardware problem. It sounds like a problem with the monitor. It sounds like the fan is faulty. This is probably the buzzing noise. And if the fan doesn't work, it will oftenly cause the computer to act strangely. The monitor is turning off from the heat that has collected in the caseing. Try to turn it on again (the way you do when you try to get it to work) and then check to see that the fan is spinning and it is spinning freely. (nothing is stuck in the fan blades, slowing it down.) Hope this helps! -TWA

I now have OS X 10.6.8 installed.
I switched my iMac on today and logged in, loaded to desktop. I clicked the apple symbol in the top left corner of the screen and BAMN, it shutdown before the drop down menu even appeared.
I copied out the system log, from console. I'm hoping someone understands what happened? I'd love to know. Many thanks. Check my profile for more system specs.

IMac random shutdown w/10.6.7 update
I'm also noticing some weirdness today after installing 6.7 yesterday.
My 2006 iMac would not wake up from sleeping last night - requiring a hard reboot. I held the restart button in back down for an unusually long time before the white light in front lower right flickered many times for about 1/2 a second before giving me many beeps (I couldn't count) then shut down. Then a few minutes later, after clicking a window (browser I think) the iMac restarted. I THINK it beeped again (not positive).
Another thing is that the Parental Controls on one user is not working.
Scrolling is jerky: Mighty Mouse, Tracking 2nd to last bar on right, Scrolling all the way to right, DC 3rd from right, Scroll without inertia. I did notice bursting and stopping with scrolling.

After being convinvced that the motherboard may be bad, I saw a YouTube video of the mo/bo harness being replaced. According to this person, technicians informed him that they would replace this part before the mo/bo or power supply. *Apparently the harness was problematic for the 1st generation iMacs. Can anybody confirm this?* Or are my symptoms pointing to the mo/bo like the Apple Store person said?

Random Shutdown. PLEASE HELP!!
Hi guys. I'm desperate for some help here. I've just bought a MacBook Pro from eBay. When it came it had Tiger installed and straight away I did a clean install of Leopard. After that, all I did was set up BootCamp with Vista and transfer some files from my external HD.
However, after a bit of use, my MacBook seems to just switch itself off completely! I'm starting to really worry about it! I've just installed a new software update and it hasn't done it since but that was only about half an hour ago.
I got the MacBook quite cheap so I really don't want to send it back and have to part with MORE cash for another one.
Has anyone else experienced this and found a solution?
Thanks, Killian.Just to update; for now, it seems that software update may have done the trick. I will be over the moon if it has!!
Still early though! -
Please Help! My brand new imac randomly disconnects from the internet. We have a BT hub - wi-fi. I have googled this issue and see that it is relatively common and it is incredibly frustrating. sadly, I have been unable to wade through the suggestions others have had as to how to solve the problem as i have no technical knowledge and am basically baffled by the list of suggestions. Please can anyone explain why this happens and what to do? It is fairly simple to reconnect each time but it is driving me mad having to. It generally happens when the computer is asleep but sometimes in the middle of doing something. Thanks!!!!!!
What frequency, security are you running? It would have been helpful if you specified in the first post.
Did you create a new Location in System Preferences->Network pane, Location pull-down. Create a new custom named Location. Then after you create that new Location click on the 'Apply' button to save that new custom named Location. See if that helps.
Lastly a lot of people have reported that WEP in lion is problmatic and it would be better to use WPA2 if you can. -

I have removed avast security and repaired disc permissions .Also carried ot AHT
Im in a panic now as well as my machine !So, is Avast still showing up in the crash logs?
Have you blown the dust out lately?
Get Temperature Monitor to see if it's heat related...
http://www.macupdate.com/info.php/id/12381/temperature-monitor
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 (Users & Groups in later OSX versions)>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...
/private/var/run/StartupItems
/Library/StartupItems
/System/Library/StartupItems
/System/Library/LaunchDaemons
/Library/LaunchDaemons
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?
How much RAM & free Disk space do you have also, click on the Memory & Disk Usage Tabs.
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? -
I having a problem where my iMac will randomly shut down without warning. Doesn't matter what app I'm using. The weird thing is that it ONLY happens after it has gone through a sleep/wake cycle. It doesn't happen after doing a cold start. The random shutdown happens anywhere from 30 secs to 30 mins after waking. I've tried the SMC reset, didn't help.
It is really starting to be a pain because I prefer to put it to sleep instead of shutting it off. Please help.I'm having same problem. Random shut downs are truly random with shut down interval changing from 2 seconds to 20 minutes or more. I've tried everything, including reset SMU, PRAM, disk diagnostics. Disk checks out. I also deleted the com.apple.PowerManagement.plist file, then reset SMU again. No go!
From what I have read seems like a power supply issue. I guess I've got a good run since buying this iMac in Aug 2005. I read on another thread that www.synaptech.com has reliable replacements.
If anyone has any other ideas, then please share!
thanks and good luck! -
Overheating or random shutdown?
Last night I while I was using my iMac it randomly shutdown twice, one right after another.
I have had the random shutdown problem in the past but have not experienced one for quite some time. (I had taken several steps to fix, including running the disk utilities and deleting some power management file. Whatever I did seemed to be working.)
I had also been using iMovie, exporting movies, all day. I had also been heavily using iPhoto and Firefox, moving photos out and onto Facebook. The case was hot to the touch and iStatpro said that the power supply was around 159 degrees F and the CPU was around 135 degrees F. Is it possible I triggered some sort of safety cutoff?
Please help me out here. I love this computer but the random shutdowns are totally killing it. Thanks in advance.Hello All,
Here's my experience with unexpected shutdowns...
My 20" Intel iMac is 6 months old - August 08.
- After shutting it down one evening as per normal, it just wouldn't turn on the next morning. Nothing I did worked: different power socket, changed the fuse (UK plug) etc. When I had just about given up carrying it around the house, it suddenly came back to life. Went to the shop to buy milk, got back and off it was again. Weird. So I spoke to Apple Care who suggested I take it down to the Apple Store in central London, UK. I laboriously did so (try taking the underground with an iMac... not fun) and dropped it off mid afternoon.
- Got a call the same evening from Apple Store: my iMac turned on fine first time (typical), tests were being run on it (basically stress testing the processor with multiple processes), and it was fine. No fault was found, I could go and pick it up.
- So I take it back home the next day, again battling with London commuters with my heavy, bulky iMac box and plug it in. All fine. Work all day on it as per normal (nothing intensive). Then at about 10pm, it just turns off. No warning, nothing. Just off, and this time its staying off. I let it cool down, nothing. Diffent plugs, nothing. Change the plug fuse, nothing. Next morning, nothing. Its dead.
- So I head off directly to the Apple Store again, iMac in hand, and battle it out again with London commuters on the underground. I explain the situation, am promised this will be a priority repair...
- Eventually, after 10 days (Christmas got in the way), I get a call that it is ready. Two items of hardware were changed, namely 1) power supply and 2) Cable/DC Power/SATA/Inverter. Though none of them were actually faulty, they are the items that can cause sudden shutdowns...
- I pick it up, and it seems fine since. But upon switching it on, I noticed the whole bottom half of my dispay was dim. Bright at the top, grey at the bottom... Another chat with Apple Care (by then am on first name terms with the whole team), we do various hardware resets to no avail. Am advised to drop it off at Apple. So off I go to the Apple Store again.
And I just got it back again.. with a new LCD display...
(http://discussions.apple.com/thread.jspa?threadID=1730239&tstart=0)
So the cost of all repairs to my 6 months old iMac is now more than half of the overall cost of the machine. Still, credit to Apple for not quibbling on any of the above issues, and fixing them (relatively) quickly and efficiently.
Now lets hope my iMac stays on and stays bright... -
To Everyone with Random Shutdowns! (Solved! REALLY!)
Hey all,
I had posted about a week back about my Macbook (Core duo white, late 2006), it was having the same symptoms as some of the others with the known random shutdown syndrome (RSS). Like many others I had thought it was the end of my macbook and the logicboard needed replacing because that is what the 'genius' people do, but I was still wondering what would cause it. It would randomly shut off! (or so I thought) I'd be typing in Safari, watching a youtube video, and even playing games, it would just shut off and I could hear the hard drive spin down. I'd restart and it would do it again sometimes right away, sometimes hours later.
This got me to thinking (like others have said) that it must be an issue with over heating. To test my theory I backed up my HD, and tried to reinstall Snow Leopard after zeroing the HD (as a fresh install). During the install process the Macbook's fan started to get loud and then it happened, it died again! So, this proved to me that it is NOT a software/OS issue at all, which means the said efforts in other posts of changing screen saver and energy saver settings had nothing to do with the cause! Aha moment!
I thought to myself... something is making it shutdown, obviously, and has to do with too much heat as the fan was going crazy even while reinstalling the OS. After reading many posts on different support forums I came accross the possibility that it could be the heatsink and/or sensor that is attached to it. I also found out that this "RSS" only applies to the non-unibody, core duo, and core 2 duo macbooks... you know what that means?
These models are the only ones with the shared memory and GPU on the same heatsink! GAH! A possible solution presents itself? To make a long post even longer... I removed the keyboard, carefully unscrewed the heatsink and fan and what did I see? Cracked and dried out thermal paste on the CPU AND GPU, they are both under the same heatsink after all, this was bad, really bad.
Luckily I had some Arctic Silver thermal paste in a tube from years ago when I upgraded my PowerMac CPU. Using some rubbing alcohol and a soft cloth I removed the crud on the heatsink, processor, and GPU (I might add that there was way too much paste on there in the first place). I waited an extra few minutes to make sure the alcohol evaporated, and then I applied a small (dime sized) amount of thermal past directly onto the two chips, I aligned the heatsink carefully and gave it a very small gentle push down onto the chips, reattached the sensor wire to the mainboard, and screwed the heatsink back in.
After putting the keyboard back on and making sure all screws were in... I immediately turned on the laptop and reinstalled the OS. The OS install took approximately 10 mintues! (crazy!) The last time I did that it took over 30 mins to install! I was stunned!
After the OS installed I let the computer idle and shut down, I let it sit for about an hour to allow the paste to contract as it cooled. After starting up again I immediately downloaded Temperature Monitor and installed it (I did have it running when my mac had RSS by the way), here are the results to prove my theory:
My Macbook with RSS:
CPU1 and CPU2 Idle temp - 114 degrees (F)
Heatsink temp - 128 degrees (F)
Approximate over heating temp - 184 degrees (F) (causing the heatsink sensor to shutdown the laptop)
My Macbook with new high quality thermal paste:
Idle temp of CPU1, CPU2, and GPU - 77 degrees (F)
Heatsink temp - 84 degrees (F)
Running temp with adobe CS4, youtube, and typing this message - 103 degrees (F)
Pretty amazing if you ask me!
Before I applied the thermal paste my Macbook took at least a minute to start up with a fresh OS install, now it only takes about 15 seconds! I have not heard the fan spin up and go crazy since! And I can't even explain to you how much fast it is now!
This does prove that Random shutdown syndrome (RSS) is caused ONLY by your GPU over heating due to old thermal paste between the chips and heatsink! A design flaw by Apple? probably not because thermal paste will crack and dry over time.
This also proves that energy conversion to data in the chips can decrease because of over heating, causing the computer performance to dramatically drop!
So before you take your out-of-warranty macbook to Apple or a repair shop, see what your internal temp readings are and try to replicate the problem with over heating your CPU/GPU! This was a 10 minute fix! I am still amazed at how much faster everything is, and haven't had a random shutdown since! I hope this helps alot of people that think they are out of luck and have to pay to get it fixed!
- Cory -I too have this problem as well and it has been getting worse lately, I don't know what to do anymore. Here is a little info about my macbookPro. I have the late 2008 unibody model, i bought it in late 2009 Refurbished from Apple. Recently my mac has been turning off out of nowhere. I may be doing something and all of a sudden it just shuts off, it usually happens faster when i start to open up more programs like Photoshop or Final Cut Pro. My mac is out of warranty now and i dont know how much apple is going to charge me to fix it. i mean they want 50 bucks just to talk to them on the phone (ridiculous if you ask me)!.

Hi,
My Macbook is just over a year old now still under applecare, I had random shutdowns before and did the firmware update which fixed it. Yesterday, I had the +please hold down the power button...+ message and so did thinking little of it, after all it is not uncommon to have to do it once in a while. Since then though it has been intermittently restarting all on its own and occasionally throwing up the +please hold power...+ message. Interesting to note is the optical drive noise when it restarts itself. I know how it should sound, the kind of mechanical movement sound that happens when you restart normally (or launch parallels and windows grabs hold of your drive). However, occasionally on these restarts it pauses during this sound several times making the same noise but stuttering through it... Strange!
It seems that I can often make it restart or throw up the power button message by just lifting up the front of the computer, as you would if you were turning it around or something. This leads me to believe it's a hardware fault... Looking under the battery compartment the two outside screws that are on the battery connection side were loose and nearly falling out so I tightened those back up, still the problem persists.
After the last restart message I copied this error report, I have no idea what to look for, just wondering if anyone can see anything helpful?

I have tried a PMU reset, PRAM reset and whatever it is that happens when you hold the power button when you turn it on to make it beeeeeeep... The issue happens with or without the power cable attached.
Unless anyone can suggest anything here I'll be taking it to the repair centre...
Thanks for reading!Ok, this is not an answer but it may help you a little: have you checked your logs? It may be an indication of what has happened there. If you don't know the drill: go to console under applications/utilities, select logs, and go there to /library/logs/panic.log.

Another iMac Randomly Shutting Down!!
Hey Everyone. I'm new to the forums, though i've always used them as a resource over the years to learn more or troubleshoot issues. Hopefully, now, someone can help me with mine personally.. :-/
I have an intel 2.8gH Aluminum iMac that I purchased fall of 2007. Only now, almost 2 years later is it suddenly (just started yesterday) turning off randomly. Everytime it will not allow me to turn it back on until a minute or so has passed. I have reset the SMC as well as the PRAM several times. This afternoon, it is now to the point where I cannot even keep it running long enough to download an app to up the fan speeds. Although, I don't think it is overheating in the first place.
I'm really hoping it is just the power supply, as I've seen that be the fix for SOME iMacs i've found at other online forums. Though, the upper corner of my iMac is not hot or smelling burnt out at all. I have found more than several online forums of people complaining about their iMacs randomly shutting down, and am praying it is not the logic board, as that is a $900+ fix.
please, someone give me insight to how i can check if its the power supply or something else? I use this iMac for recording all of my music, editing video, and (of course) playing WoW lol. Currently using my 1st gen macbook.I bought my iMac 20" in May 2006. I had been very impressed with it until one day I shut it down to move it to another room. I could not get it to turn back on. I had to leave it unplugged for a few hours. Since then it has started randomly shutting itself down, turning itself off and not starting up again until I unplug and leave it unplugged for a few hours. I had purchased the Apple Care? Extended Warranty, and the fault occurred during this three year period, though I failed to take the fault seriously and did not phone during the period. It was just after the three year warranty that I phoned Apple Care? about it and everyone I spoke to said they had not heard of this problem occurring. I wonder now, why the Apple Customer Service Team don't visit the discussions.apple.com where they will find quite a significant number of like problems occurring with the iMac sold in 2006.
My reason for paying the nearly triple price point for an Apple Computer was the quality of the build and my expectation that I would get far longer life out of my purchase. I don't like buying throw away products and I gladly save and wait longer to buy better quality products. Just as an example and point of reference. In 2000 I purchased a second hand Dell with 8GB HDD and 256Mb RAM. I paid $1000 for it and I gave it to my father when I got this iMac and he still has it running today. It has not had a single hardware issue in nine years. Good luck I suppose. However, after spending around $3000 on this iMac, and Apple now telling me the Logic Board is generically, non specifically 'failing', it goes against my pure desire for non disposable, throw away products to buy another Logic Board for AUS $1064. For one, I don't believe it has given me anywhere near the life that I expected from a product with such a high price point and solid reputation for quality, nor do I feel confidence in buying anything more 'Apple' after the dealings I have had with them over this problem. I am amazed that Apple would sell a 'failing' Computer to their customers and then expect that the customer will spend more money, considerably more, on a product that may be equally faulty and that they will not stand behind either. -
Are the replacement Heatsinks fixing people's Random Shutdown problems?
Is the replacement heatsink (the shorter one) still the method of choice from Apple for fixing Random Shutdown problems?
Is it working for people who've had it done recently?Does this max out the CPU?
Yes. People who advocate this are testing to see if it's possible to induce a "random" shut down.
Why would anyone want to do that?
Good question. I've seen two reasons put forward: (a) It's better to make it happen now yourself rather let it strike out of the blue at some later date (and if running this test doesn't induce RSDs you can feel confident that your computer is probably immune); (b) If you take your MacBook to an Apple Store it could be useful for demonstrating to an Apple "genius" that your computer has the problem, especially if your shutdowns are infrequent.
(personally, I don't agree with (a))

21-inch / 21" iMac Random Shut down
Ok, I have a refub imac, mid 2011 model. I have random shutdowns, not often but they do happen. I have swapped out and replaced ram by three different OEM's chips. I am trying to get 12gb installed. I have been dealing with applecare support from the start of the problems. No solution. Any suggestions. I am wanting to them to replace the new imac now. Apple had replaced the logic board and power supply too. Frustrated.
What makes you think it's the RAM causing the shutdowns? If you keep taking it back to Apple you may get a different unit if they can't fix it to your satisfaction. Three or four failed repairs and they repalce it, I thnk.
