IMac turning itself off?

i have been using my imac less than a week and in the last 3 days it has shut itself down on it's own four times. i'm a very busy photographer and really can't surrender my imac for a week or my business will heavily suffer.
i've read a whole bunch of threads on here about other people having the same issue but it doesn't seem that there is a real 'fix' for it yet?
if anyone has any insight i'd greatly appreciate it.
i have a july 2010 imac i7 quadcore with OWC installed 16gb ram and a OWC installed esata port. 1TB HD (i keep all my files on a lacie "4 big".)

the power plug is connected just it should be.
it has only done it while i was working at it, not necessarily while using the keyboard.
i don't store any data on the computer, it's all on my lacie 8TB raid external drive so i'm not worried about losing data. just if i am working in photoshop and am not saving after every single edit to a file i will lose the work that i've done.
i have the wireless keyboard and magic mouse.
looking at the console after each shut down (and i start it back up) it says that apple can't open the crash reporter?
in other threads it seems to be an issue with having 16GB ram, other people have downgraded and been able to work without shut downs. i don't want to downgrade though. i work with thousands of raw files (fairly large file size) and need the fast performance to be able to edit photos quickly.

IMac turned itself off and won't fully turn back on

My iMac turned itself off this morning; all I was doing was typing, nothing intensive. It wouldn't turn back on.
I first got a wired keyboard and mouse and tried resetting the SMC. No success.
Next I took out and put back in the RAM (and it was unplugged). After repeatedly pressing the power button, I got a single beep out of it. I personally don't think it was high enough of a pitch, but I read that it might've been because the computer didn't read any RAM.
I might've again taken the RAM out, this time also unplugged. After more repeated pressing, the fans came on, but then dead again.
The third time, the fans came on and half of the dong played, but it was cut off.
The forth time the dong fully played, but a second after, it turned off again.
All of these times involved unplugging the computer for a few seconds and then repeatedly pressing the power button; I might've taken the RAM out all of the times too, but I don't remember now.
Two or so weeks ago, I did have a kernal panic while I was editing in iPhoto, and I believe it's the first for my iMac. About a month and a half ago I had a graphics problem where using exposé to show all windows caused the whole screen to become jagged 'shards' of colour (it reminded me of broken pieces of glass). While a restart fixed both of these problems, the graphic problems are not new for this iMac (though I had never had the shard effect before).
Two more little things that I'm unsure if they're related: last night, it turned itself on from sleep, but it does this every other night, so I don't think last night's special; and every time I got it to turn on, I felt that I had to give the power button just a short burst of force, as if holding it for even half a second wouldn't get it to turn on.
Does this sound like the logic board, or less expensively, the power supply? Since it attempts to come on here and there but gets cut off, what does that say with respect to the logic board?
The computer turned one year in August 08, and there's no AppleCare. Even though the warranty's gone, would Apple have any negative view if I opened it up to get my HDD? I can get the screen off with three house suction cups; my HDD was last backed up four days ago, and of course, I had just typed about 3000 words for a story I'm working on between last night and this morning.
And lastly, if I make an appointment with the Apple Store (two hours from here...) and they want to take it in, will they take out my HDD right there and give it to me if I don't take it out? Four days is so tremendous in this situation. I will not part with my HDD.

Perhaps. While I guess they're certified, I still trust Apple the most. Also, if it is a logic board problem, and it is widespread, hopefully this could be free. I don't know how a reseller would handle such a situation. I just want a file off my HDD!
I can confirm that it never really powers on unless it's been unplugged for at least a few seconds. So far, the longer it's been unplugged, the longer it stayed on. There were hours between the times I almost got into my account, and then the login window.
I again switched the MacBook and iMac's RAM, but doing this makes a senseless result. The MB's light simply stays on (no fans or screen, but when I turn it off, I do hear it 'de-whir'), and the iMac just quickly turns on and then off, as it has been after a 5-30 second unplugging session.
I guess this is the rebellion of a Revision A machine.

IMac turns itself off during start up

On a 27" iMac I installed the Yosemite 10.10.1 upgrade from the App Store and on restart it turns itself off after the logo and gear are on screen. Unit will not start in safe mode. Now what???

Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the 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.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main 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.
Reinstall OS X: Select Reinstall OS X 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.

HT1379 On trying to reset and restart iMac turns itself off

On trying to restart and reset iMac turns itself off

Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.
Isolating an issue by using another user account
If the problem is still there, try booting into the Safe Mode. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart. For each disable/delete, you will need to restart if you don't do them all at once.

IMac turns itself off after an attempted RAM upgrade

I took the 1GB from the memory slot and installed
2x2GB which didn't work so replaced the original
1GB and now it shuts itself off after about ten
seconds of attempting to reboot. I've tried all
combinations but nothing works.

Doug,
I work as a sys admin at a college, we bought 90, 20" I Macs last November, we have had 3 break so far with the same problem, and one with a failed motherboard as a result of a bad power supply.
I have been a mac user for over 10 years and to have machines break after 2 months of use is shocking for a company that previously had such a good reputation for quality products.
This is a known issue, and the company that fixes our machines under applecare has admitted that these machines have a faulty power supply. I know the Rev A models had issues with power supplies, but the fact that all the 20" models have a 150 watt power supply doesn't help as this is not enough power to run a power pc plus 20" screen etc.
If i were you i would get it sorted straight away as other people have had this issue and it will only get worse if you dont get the power supply replaced.
Regards,
Kevin.

Weird clicking sound, iMac freezes or is dead slow, and turns itself off!

I've had my iMac for a good 3-4 years, during which it has been fitted with a new hard drive.
About a year ago, during watching DVDs, there was a weird click-clack sound for a good 10 seconds which was followed by the freeze. Sometimes it would go off, but sometimes the Mac would turn itself off like it had run out of juice. I thought it might've been a power issue.
Nowadays it almost every time presents this clicking sound, and freezing is inevitable. Sometimes there's no warning, the power just goes off. I have unplugged all devices that are using power ie. iPod, but the problem persists.
Could this be a mere power issue? What can the clicking sound be a symptom of?
I'm doing back-up in case the Mac completely shuts down, but I have hope for the machine yet!
I have few months warranty left, keen to sort this out pronto! All comments warmly welcome.
Anne

As I was making the clone with SuperDuper, the process was halted by an error, and I found half of my stuff copied on the external hard drive. It had enough space, but it prompted a dodgy file in 'Frameworks' in the Library which stopped the process. It all looked very benign, and I checked the troubleshooting and it suggested to try again after restarting.
What in fact had happened, was that ALL my music files had disappeared from my hard drive, none of my applications would work on my Mac, even Safari or iTunes, and I was left last night with the blue screen of death. These files were nowhere to be found, ANY of the hard drives.
Ready to chuck the piece.
Thanks for all your advice but this time, it made it worse. I'm getting the Mac a new hard drive as it's still under warranty. As it's the third time I've lost my files, there's hardly a scratch on me.. Taught me not to get attached to things too much.

IMac turns itself on during the day

I don't know what is going on. All of a sudden my iMac turns itself on in the middle of the day. It is off when I leave for work (not asleep) and on when I come home. It only seems to happen during the weekday.
I have EyeTV on my computer which can turn it on before recording a program, but I don't record anything during the day.
Is there a log file I can look at to see if I can figure out what is causing it to turn on?
Thanks!

When you go there hit the "Schedule..." button and see if it selected if you havent already done that and then id see if your permissions are messed up its unlikely but if the powermanagment systems perrmisions get messed up it can cause things like that to happen

Does anyone know why imac shuts itself off when importing a cd into itunes?

very, very frustrating and disappointing. trying to import a music cd into itunes, left room, returned to find that the computer had turned itself off, disc still inside. started computer back up, cd was still on desktop, started itunes but the cd did not appear in itunes. searched and found all but one song had been imported, directed itunes to import that one track and itunes ballooned. had to force quit and force eject cd. this has happened before, but not for a while. i just don't understand why it just can't work. this is supposed to be such wonderous, and awe inspiring technology (what a supreme joke!), and the only thing that any of this technology is good at is collecting information and advertising. this is not just a mac problem, i've noticed that windows users are having the same issue. ridiculous.

Hi again Susy!
As that website says, I would recommend following these steps to determine if there is an issue or not:
After listening to the example sounds, if you feel that your optical disc drive is making noises in excess of these examples during normal operation, please contact AppleCare for assistance.
Thank you for using the Apple Support Community. Due to the nature of your issue or question you may find more information by using another one of Apple's support resources - https://expresslane.apple.com/GetproductgroupList.action.

IOS4, Fully Charged 3GS turned itself off, Missed an appointment

OMG, my fully charged iPhone 3GS just turned itself off and I missed out the morning alarm and an early morning appointment.
Its updated to iOS 4; Its never happened before. Morning when i turned it on, it just is working from where it left off previous night..Anyone else having these issues.
The Phone was fully charged and when turned on, it shows me 98% battery. The only thing to mention was, phone was sitting on its dock connected to a sleeping iMac.

Hi All,
anyone else having this issue? I have read that iPhone 3GS is turning itself off during calls but mine, didn't happen during call. It just turned itself off while connected to dock and in sleep mode...

My iphone keeps crashing and turning itself off.....even though battery life is fine...as soon as i plug charger in it comes bcak on....help very frustrating...3g

absolutely that is frustrating. if the battery life is fine there could be two things software or hardware. to find out if your back up your information in itunes and import pictures and then restore the phone as NEW then you can test it out. if it is still shutting off it is hardware related

IPhone 5C - Turned itself off and won't come back on.

I have owned this phone since the day it came out (20th September) and it was fine up until a few weeks ago. It decided - frequently - to reboot itself, lines would appear on my screen and the brightness would decrease until the phone turned itself off. Soon the apple logo would appear and everything would be fine. I noticed that it would do this while I was on it while it was charging or when a lot of apps were open. I avoided doing these things, but it still would happen. Sometimes it would do it and the apple logo would not appear - I learned of the holding down the home and sleep/wake button at the same time hack, and would do that to get it back on. As time went on the problem would persist, sometimes it would take a few attempts to get the phone back on - I removed some recent apps and the phone was fine for about a week.
Last Friday the phone did it again, so I decided to factory reset/restore through iTunes and then restore my backup. For a couple of days the phone was fine, up until last night where the phone switched off - thinking this was like all the other times I did what I'd usually do. But nothing, I've left it to charge, I've attempted to restore it. When I go to restore it the apple logo appears and the process bar appears, however iTunes turns around and says that it cannot restore the phone.
I went onto here to try and attempt to have it sent back for service, I put in my IMEI number, and it said that I need to turn "Find my iPhone" off, I did that and now it says that it's still on, when it isn't!
Does anyone know what I can do? Or shall I just ring them and figure out how to send it back through that?

This happened to me yesterday. This probably isn't any use to you now, but for others with this question. This morning I took the back off of my phone, and I took the battery out and plugged it in to my laptop. It immediately lit up. We put the battery back in and restored it and it works better than ever. Not sure if this will work for all, but it worked for me!

My iPhone 3GS keeps turning itself off all the time for no reason every time I put it on silent or just get a Facebook message I have a broken sleep/power button anyone know how to fix this problem?

My iPhone 3GS keeps turning itself off all the time the power/sleep button dosent work so it's quiet annoying having to plug it in all the time dose anyone have a fix for this?

The "fix" is to get the phone repaired. There's no magic solution for a broken phone.
Bring your phone ant $149 to Apple for an out of warranty replacement, or find a 3rd party repair shop near you.

My MacBook Pro just turned itself off while installing Windows 7. It has now got a black screen with a white flashing bar in the top left corner...what can I do?

I was just installing windows 7 onto my MacBook Pro. I selected to have 200GB for Windows and the rest leave for Mac.
I clicked install and the bar filled up as it should do. However, once the install had completed, my MacBook turned itself off. I assumed this was normal. Now, my MacBook has a black screen with a white flashing underscore in the top left corner.
What is wrong and what should I do?

Hold down the Option key when starting up then on the sceen that comes up select Mac OS X to boot from.
The Win 7 install didn't go well and is hung in some way. You should use boot camp assistant to remove the win partition and start over.
Make sure you are using a Retail version of Win 7. A Branded OEM version, like ones from Dell and HP, will NOT work to install Windows 7 on your Mac.

Hello untech,
I see that it has been awhile since you have posted with us on the HP Forums. Please let me take a moment to say "Welcome Back".
I see that you are having an issue with the printer shutting it self off and not powering back on.
By chance do you have the printer power cable connected to a power bar/strip? If so, please try connecting the printers power cable directly to a wall outlet. Here is a document that explains the Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector.
The printer in the document is a LaserJet printer but this document is meant for HP products in general and only uses the LaserJet as an example.
I am also going to include a document for when The HP Printer Won't Turn On or Respond When the Power Button is Pressed.
If by chance the issue is not resolved after doing the steps outlined, I would then suggest calling HP's Technical Support to see about further options for you. If you are calling within North America, the number is 1-800-474-6836 and for all other regions, click here: click here.

Computer just turned itself off and now cannot turn on

Hi. I have a HP Touch smart 310 PC. The last week it has been sounding like it was about to take off, I thought at first that it might of been struggling with to much internal memory. So I went in and deleted a lot of files and photos, this didn't seem to do anything as I was on it it just turned itself off. I turned it off at the power overnight and tried to restart it in the morning but I had no luck. The power button on the side usually light up but unfortunately does not. I have pulled out all cords turned off power. What I have noticed is the power adapter around the back is coming up green. Has anyone on had the same thing happen and if so what did you do. Many thanks
