IMac starts boot then cuts off

My iMac was working fine. I got a message that the memory was almost full then it just cut off. Now when I try to turn it on, it goes to the white screen, The booting bar comes up, but as it starts to boot, everything just cuts off.

You may have totally filled your internal HD adn need to move libraries such as you iTunes, iPhoto or iMovie libraries to an external HD. Please attempt to boot into Safe Mode by holding down the Shift key when you hear the startup tone until a progress bar appears. If you can do that then move those libraries to an external HD and then attempt to restart.

Hi
My Powerbook was the same. Only fix is to reinstall OSX from the install CD but be sure not to pick the Format and install clean. Once you boot with the install CD pick the preserve user data and settings.
On My machine the reinstall looked perfect. My network, email, files and all the programmes were all there. Most apps worked fine but Adobe CS2, Virtual PC and NetBarrier all needed reinastallation as they reported a few files or registration was missing. I went for the 10.4.3 upgrade again and it worked fine.
Good luck

Fans (cpu/case) run 1 second then cut off, computer won't start.

Pavilion A6614F, this computer is stock from the factory.
Orginal problem, fans would spin for 1 second, then cut off.
eliminated "Everything" from the Motherboard, same problem.
This computer was looked at by a computer shop and they couldn't fix it.
It was given to me to repair.
Power Supply checked good, but still tried new 850 w PS I had, same problem.
New Motherboard, (M2N68-LA (NARRA3)) same problem,
New Processor, Phenom 9500, in the new motherboard, same problem.
swap CPUs between Motherboards, changed battery, cleared CMOS, no help.
this is with nothing plugged into the MB, no USB, memory, wlan card, keyboard, mouse, "Nothing" but 4 pin cpu power and main board power plug, on/off switch.
It appear to be "shorted", but where, was the Motherboard isolate from the case by the factory, I never found any when I removed the MB.
I've checked the wires from the on/off switch to see if they were raw/shorting out, nothing that I could find.
I find it odd that the fans come on as soon as the power cord is plugged into the PS, and without pushing the start button, but they only spin for a second or two, then everything is dead.
The fan in the 850 watt PS stops spinning as well, which makes me think it's shorted, else why would two motherboards/CPU exhibits the same problems,
and what occurred with the original Motherboard that created the problem???
I even tried running the MB outside of the case and on the desk, no luck.
I've builded/repaired more computers than I care to remember, but this one is a major problem,
If this motherboard was not isolated from the case, ( it is not now ) or the on/off switch not bad,
It's possible I could have gotten a bad MB or CPU, but since the symtoms haven't changed, I don't think that is likely.
Any "suggestions", short of using it for target practice. lol

The original PS is working, light stays on after fans stop spinning.
I'm checking with a friend who may have a MB these CPU will fit in to see if they're working OK,
and maybe a CPU that is known to be working to try in these two MB,
That's about the only way I have of checking the MB and CPUs.
I've made a visual check of all Capacitors, none seems to have "blown their top".
I may not have made it clear in my first post, but the fans start to spin as soon as the power is applied to the PS, and this is without anything connected to the MB, not even the on/off switch, but they still spin for a second or so.
I don't know if this is a characteristic of all AMD MB, or a symptom of the problem.
If it was just a voltage surge to charge up the capacitors, then cut off, I could under stand it,
I mounted the old MB/CPU in another case but got the same results.
Personally, I'm as Intel man myself, and have a wide varity of intel MB/Sockets to check most of their products,
I've never liked AMD, and finding more justification for that everyday.
I appreciate the suggestions and help, if you have any other suggestion, I'd appreciate them too, I've ran out. LOL
When I do find the problem, and I will, sooner or later, I'll come back and let everyone know, I'd hate to see anyone else in this predicament.
Thanks again.

Basics from the manual are restart, reset, restore.
You can also try removing and reinstalling the app

Everytime I click on an app, it loads then cuts off, and then goes back to the home screen. What do I do?

While using my imac the display just cuts off whats causing this

while using my imac the display just cuts off but the machine is still on and I have to push the power button a couple of times fir it to cut back on whats causing this?

Hi keithfromcapitol heights,
It sounds as if your iMac is going to sleep unexpectedly. Is this during use or after it has been left alone for a while (which can be normal if it is set that way?) If during use, I would suggest that you reset your System Management Controller, using the steps in this article -

Mac book starts to boot, then turns off

I have Mac Book Pro (13", Yr2011) which will not boot. It has a 1TB HD which has been partitioned for Mt Lion (primary) and Snow Leopard. The computer has worked fine in this configuration. For about 6 wks, the computer was not used and apparently the battery charge depleted to zero. When an attempt was made to use the computer with battery only, the screen was just light gray with a circular wait icon. After several minutes with no change, the battery was noted to be discharged. A charger was connected, but there was no change in the screen. The computer was then turned off and left to fully charge. On first attempt to turn on, the computer did come to life. However, when attempting to Update software, it displayed No Internect connection - even though it was connected by ethernet. The computer was power cycled, however the screen then again only showed light gray with wait icon. Now when attempting to boot, the screen shows light gray, circular wait icon & horizontal bar graph indicating something is loading. After about several minutes, the bar graph fills & disappears, however, the screen remains light gray with wait icon - indefinitely. On a few attempts, the computer and screen simply turned off after about 30secs.
If I hold the Option key while powering on, then the Mac does boot ok to Snow Leopard. Apparently, the Mt Lion side of the HD was corrupted during the low battery boot appempt. The last time I backup MtLion was several months ago, so if I prefer not to reformat and reload from scratch.
Since the Mac did boot up once, I'm wondering if there is a way to recover without having to reformat and start again.
Don

Tough without the Install disc, but some things to try...
Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
/sbin/fsck -fy
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).

Imac tries boot and turns off

When I turn on my iMac, a white screen with an Apple logo appears with a rotating circle right below the logo. After a while, it fails to boot and turns off. I tried turning the computer on while pressing Command R or Shift Command R P but nothing seems to work. Pressing those buttons while turning on just makes the computer turn off sooner. Does anyone have any suggestion?

Hello DESOMBRE,
It seems you cannot successfully boot up your Mac or enter recovery mode. Based on the information you have provided, it appears your iMac needs to be serviced. The following link should help you get started with the process and has links with additional information on topics such as warranty and service pricing, battery replacement, and express replacement service.

Phone starts booting then aborts

I have just updated my iPhone OS to 3.0 release, after having been using the dev beta. I now find my phone start booting (shows the Apple logo) and then after a few seconds aborts and turns off. I have tried connecting it to the computer, to the wall adaptor, leaving it for a while, but nothing seems to make a difference.
Any idea on what I should be trying to do?

Looks like I should have searched before posting. Looks like there is recovery mode:

Iphone 4s freezing at start up then shuts off and keeps restarting then repeating that process over and over. I have tried to reset the phone two different ways and still this problem occurs after I update it or turn off the phone.

yes the title says most of what is going on.
I recently reset my phone, losing all contacts and pictures. It was working fine, then after I updated it, it will not turn on completely.
It starts up with the apple logo
-goes to the ios 6 (please slide to open) screen
-then shuts off
-and repeats the process unless I shut the phone off manually
I have tried to hold the lock and the home button down to manually reset the phone
I have also tried reseting the phone completely previously, and I still have this problem.
Any ideas?
Thank you!!

I really don't have an answer for that one. I guess that while trying to get things working correctly, I would use the most basic monitor I had which in your case would be the Eizon using the Thunderbolt port and adaptor.
When you boot into Safe Mode the startup is quite slow, but you should get the Apple logo and then the spinning gear below it (release the SHIFT key when it appears.) Then after a little more time you should see a gray progress bar appear below the spinning gear. When that disappears the computer will startup to a login screen.

When power on and start up my computer start and then power off

Hello
