27" imac i7 16GB RAM mid-2010 turns off randomly

I've done a lot of reading on the existing posts, and so far no real solutions except for removing RAM. I have 27" imac with APPLE-INSTALLED 16GB RAM. It is a mid-2010 imac model 11,3.
The random shutdowns don't seem to correlate to particular apps or usage. They started a few weeks ago with shutdowns once in a week or so, and now are happening about 3 times a day.
What I've tried so far:
- installed istatpro temperature dashboard thing & smcFanControl. I've been monitoring HD and CPU temps and turning up the fans to keep CPU under 110 degrees F. Did not fix it.
- reset SMC; did not fix it.
- zapped PRAM; did not fix it.
I see from other threads that others are having the same problem. The next thing I am going to try is removing RAM. I'll report back in the next few days what I discover.

It's a new machine and still under warranty. Why are you bothering to play with it? Get straight onto Apple and take it back before you do something that voids your warranty.

Macbook air (11", mid 2011) turns off randomly

My macbook air 11" (mid 2011) turns off randomly. Sometimes, in the middle of something a black screen. After a few seconds it starts up again, on using a key. It restarts in the application I worked on before. Strange!

Do you have put hard drive to sleep when possible checked? Try unchecking it.Have you tried repairing permissions in utilities? You could also do a pram reset. Command/Option/P/R keys at startup for three chimes.

Why my iMac 27 2010 turn off by itself?

Why my iMac 27 mid 2010 turn off by itself?
I already replaced the Power Supply part number 661-5972. The next thing is replace all the thermal sensors and then the logic board. I do not have any other way to find out what it 's wrong with it.
Last the same time that the old power Supply. Let it sit for a few hours. Turn back on and works fora few more days or weeks ans suddenly turn off again.
I am 66, started out with Apple around 87 as an independant service provider here in PR and have never had so much problem with any other mac's than this one.
Apple support provider here in PR have no expertise what so ever in giving us solutions to problems. Even thought I still doing some support to some of the old customer I am handicap with new technical tools to solve problems within new products. I wish Apple would have consideration on the old ones that help and support apple products without their help.
Thank you for reading my note!

I can relate Jose
Have you looked under the hood of a newer car, worked on a new toaster or coffee maker..? Most all of them have sealed components that are no longer repairable, you throw the old part away and replace it with a new part or just replace the whole thing.
Heck' for the most part even the Geniuses at the bar are unable to fix or do anything about most hardware problems. So instead of trying to fix a product that is under warranty, they either send it out or replace it with a new Mac, Pad, Pod or Phone on the spot.
As another Apple user like yourself with some hands in experience and some time here in ASC, it sounds more like either a overheating graphic's chip or bad SMC chip than a temperature sensor problem. Both of which the normal Hardware Test will not catch.
So on that note: I would probably closely monitor all the temperature sensors (especially the GPU temperature) with iStat Pro or Temp Monitor to see if you can catch an overheating component that is causing the shutdown.
It also might help to post the Consol Message for the shutdown here in the ASC forum.

with a mini display to mini display cable. Attach it to the Thunderbolt port on your MBP and to the mini display port on your iMac.
How do I enable TDM?
Make sure both computers are turned on and awake.
Connect a male-to-male Mini DisplayPort or ThunderBolt cable to each computer.
Press Command-F2 on the keyboard of the iMac being used as a display to enable TDM.

In a macbook pro i7 2.66 with DDR3 1066 MHz ram, mid 2010 I can put two 8GB ram each, I gained speed or recommend

In a macbook pro i7 2.66 with DDR3 1066 MHz ram, mid 2010 I can put two 8GB (1333 MHZ) ram each, I gained speed or recommend, or is it better for me to stay with 8GB, 4GB memory in two 1066 each

Stick to the specs give in your user manual. There is no benefit to installing faster rated RAM. It won't run any faster. Furthermore, it may not work at all.

I know the report is long, maybe several hundred lines. Please post all of it anyway.

IMac (21.5-inch Mid 2010) When booting gets stuck and spins. Won't load HELP! SOS!

Apologies to those wiser in dealing with this. I have Apple everything but am totally stumped with my iMac (21.5-inch Mid 2010) booting up and then not doing anything except sitting there with the apple symbol on a white screen with the grey mini-circular slashed like a clock little spinner going on and on and on. It seems to be freezing up and locked somehow.
The last time it did boot... I was attempting to install Mavericks. Can anyone please possibly walk me through a few suggestions?
Thank you very much!

Once you've booted into Recovery Mode, see if Disk Utility needs to repair the HD. From the four options choose Disk Utility, select Macintosh HD and click on Repair Disk. If anything gets changed click on repair disk again until you get a clean pass. Once done restart as normal from the Apple menu.
If you're still having have a look at this link for suggestions:

Imac screen image size fluctuates then turns off

imac screen image size fluctuates then turns off. I have an Imac G3 (slot drive/Grape). It is running on OS 9.2 and I believe has 288 MB Ram.It started acting very odd yesterday. First, I noticed that the image on the screen had shrunken in on the sides and was elongated up and down. I restarted and when it came up the image still wasn't right, but it wasn't as out of proportion. I ran norton and first aid which both said everything was fine. By this time the image had stretched out to its normal size. I printed a couple of things and shut it down. This morning I started it up to have a look and the image was all shrunken and stretched again. The image started pulsating then the mac shut off. A few minutes later it started up again on its own so I turned it off. Until yesterday my Mac had been working just fine. Any ideas about what this is or what to do about it? Thanks for the help.
Charlotte

The fact that it is starting up on its own either means that it is scheduled to, or that there is some problem with the power supply, which as far as I can tell, would cause the monitor to do that.

Mid-2010 Macbook Pro Randomly goes back to login screen?

My mid-2010 MBP will randomly log me out. I'll be on the internet or working on a paper and it will go to the blue screen that occurs when you're booting up the computer and then to my login screen, where I have to type in my username and password again. Anyone else experiencing this?

IMac screen turns off randomly?

Hello
I'm new to this, so sorry if I haven't posted this in the right place or anything
Basically, my iMac screen just turns off randomly, like once a week. It only happens when I come off sleep/screensaver like 2 minutes after, then I have to press the iMac button
Anyone else have this problem, or know how I can fix it?
Thanks!

Hello Heather & welcome to he forums!
You did pretty good for the first time... & this is a pretty friendly place.
Open console in Applications>Utilities, check the system log for the date/time of the last problem & the restart right after that for clues.

These computers have got a damaged NVIDIA graphic which may cause unexpected restarts, kernel panics, black screens... See > http://support.apple.com/kb/TS4088
Fortunately, Apple is repairing these computers for free, so make a backup of your data and take your MacBook Pro to an Apple Store or reseller

My 8350i turns off randomly

My 8350i start to turn off randomly a lot of times
The OS is
BlackBerry Handheld Software v5.0.0.1737 (Multilanguage)
Package Version: 5.0.0.1737
Consisting of:
Applications: 5.0.0.1074
Software Platform: 3.2.0.34
I didn´t istall any extra aplication and the meromy is clear , don´t have any picture,aditional file...
I read about this problem in many fourums and I reload the OS many times
it´s a question of harware? product quality?
what´s going on?
The problem persist

It doesn't matter how long you've been running the computer, the heat can build up fast. On my iMac, I can shut my computer down overnight, boot it up in the morning, and the temp on the CPU will be around 114 degrees F. However, if I start to do anything intensive like rendering video or playing a game full screen the temp reaches the point where the fans have to kick in high gear w/in about 5 minutes. So 30 minutes is plenty of time to get the heat built up. Besides, I think that the new C2D's are supposed to run cooler, so that means that the temp limit will be reached faster.
Also, like myhighway suggested, the RAM might be insufficient enough to do graphics-intensive tasks or other RAM utilizing tasks. When I got my iMac, it had 512 MB of RAM. That barely cut it for rendering video. Even with 512, it took over 2 hours to render just an hour of video. After that I got another 512 stick from Apple, and the rendering is real-time now. Also like myhighway suggested, the 3rd party RAM you put in there could be faulty, leaving your computer with just 512 MB of usefull RAM.
Hope this helps

MacBook Pro Turns off Randomly Only when logged in OSX 10.8.2

Hi,
I have a 2010 Macbook pro with Mountain Lion 10.8.2. For a couple of weeks now, when its not plugged in to AC it turns off randomly, not at any specific battery%.
Things I have tried already that were not helpful:
- System profiler battery: 374 cycles, Battery Status: Normal
- SMC reset
- Clean install of Mountain Lion without any Migraion of old System files (wanted to do this anyways before the problem arose)
- Its does not seem to be a heating issue, has happened at low temperatures
What I have noticed is that if I either run the diagnostics at startup or enter to recovery mode, I can run the battery all the way to 0% (lasts a while) and this random swtiching off doesn't occur. It only happens when I am logged in to OSX. This makes me think its not a battery issue either.
Any help would be great.
Thanks!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Backlight turning off randomly

I have a late 2009 27" 2.66 iMac (latest OS and updates). Just the other day the backlight started turning off randomly (can still see screen under a light). I have corners enabled and can put the display to sleep, wake it again and the backlight turns back on, but only for a short time. And I have a second monitor plugged in with no problems on that.
I've read that it may need new hardware which I don't really want to be forking out on. I've tried the other things of reseting the PRAM and SMC with no luck.
I've tried to boot AHT to run a diagnostic but for some reason whatever I do I can't get it to run.
Anyone have any suggestions?

It's probably a connection if it does it a lot when moving it. If it's out of warranty, you could use one of these guides to open it up and check for lose wires or connections.
