Shuts down while starting up

MacBook Pro shuts down before completely starting up

Try a SMC reset.
Intel-based Macs: Resetting the System Management Controller (SMC)
If that fails to solve the problem see if you can boot to either the Recovery HD or to the Online Internet Recovery system. At startup hold down the Command + r keys for the built in Recovery HD and Command + Option/Alt + r keys and hold them down until you see a globe on the screen for the internet based system. The Internet based system only works on newer Mac computers, Mid 2011 and newer systems.

Premiere Elements 11 shut down while starting; without error message

hello everybody,
pe11 worked well at my Laptop.
Since a week it always shut down while starting it.
No error message!
I already reinstalled it, tried to start with admin rights, but it doesn't work.
Thanks for your answers!

Premiere Elements 11 on Windows 7 64 bit.
Before a week ago, how long had you been working with Premiere Elements 11 on Windows 7 64 bit without problems?
Does the problem exist with and without the antivirus and firewall(s) disabled?
Is your video card/graphics card up to date according to the web site of the manufacturer of the card?
Do you have the latest version of QuickTime installed on that computer with Premiere Elements 11?
Any new programs, 3rd party plug-ins and codecs, installed?
Where are the Scratch Disks directed and how much free space is at those designated locations? Any pile ups
of preview files in the Adobe Premiere Elements Preview Files Folder or conformed audio files in the Media Cache
Files Folder.
Let us get the classic deletion of the Adobe Premiere Elements Prefs file out of the way.

Roaming
Adobe

and in the 11.0 Folder is the Adobe Premiere Elements Prefs file that you delete. If that does not work, then delete the whole 11.0 Folder
in which it exists. Be sure to be working with Show Hidden Files, Folders, and Drives active so that you can see the complete path cited.
Depending on how things are going, you might also include right clicking the desktop icon for the program, selecting and applying Run As
Administrator.
Let us work through the above and then, based on your results, we can decide what next if necessary.
Thank you.

Macbook shuts down while starting up?

Hi guys,
I have a Macbook for school and well, while starting up, I get to the grey screen with the grey apple with the rotating thing. After maybe 5 or 10 seconds of this, it will just completely shut off. Some background info, as it wasn't doing this earlier.
My iSight camera would just stay turned on so I asked my computer teacher and he told me to hold down Option-Cmd-R-P-Power while it was starting up and to do it 3 times. He told me this cleared the PRAM. Well, I did what he said and then started it back up, but then shut it down while it was starting up by holding down the power button for like 4 seconds. After that, I haven't been able to start up my Macbook.
Am I screwed? =[

Update 2:
I followed this guide (link at end of message) and have gotten a little progress.
I now have the infinite boot thing, where it just sits there twirling.

Oh....my....GAWD!!!!
The boot sequence ended and it works!!!1

Computer shuts down while starting up

I have a 400 MHz iMac, not sure what model exactly it is, but when I try to start it up, it turns on and makes the classic OS X starting up noise. The light on the power button turns on, the caps lock light on the keyboard flashes on, and you can hear the cd drive start to boot when all of a sudden the whole computer turns off.
I made sure the socket i was plugged into wasn't shorting out or anything, i also checked to make sure the ram was in there properly, but i can't think of anything else to check. So does anyone have any idea what may be happening?

EthanD...
The symptoms you describe sounds like the Flyback went out (PAV Board). You seem to get past the POST (Power On Self Test), as the keyboard light flashes, just to loose it on monitor startup. That is the last item of the self-protect cycle and down it goes.
Unfortunately unless you know how to do the work, that is extremely dangerous, it is an expensive professional repair.

Shuts down while starting up (wicked curveball)

My first generation iMac G5 has run flawlessly (aside from the dentist drill-like fan) until now. When I press the power button, the display turns on and displays the gray apple logo with the spinning startup graphic. Before it can move onto the next screen with the progress bar, the power suddenly cuts off.
Any ideas on what the issue is? What should I do?
Much obliged my brothers.

After following this document to reset my SMU (http://docs.info.apple.com/article.html?artnum=300908) my iMac still cuts power 1/2 way through the startup. That article suggests it must be a power supply issue. I started up in Safe Mode, which is quicker, and I saw all of my icons for a few seconds before the power cut off again -- so that is a good sign.
AND, turns out my power supply is covered through this:
http://www.apple.com/support/imac/repairextensionprogram/
so I'm going to take my iMac into an Apple Store and have them replace the power supply for free (hopefully)
Thanks for your help.

I have an iMac that I purchased back in 2010 and over the past 9 month or less my computer just started shutting down while someone was in the process or working on it. What could this come from? Is there a simple solutions to this problem?

MacBook randomly shuts down while watching streaming video

I've been having a problem lately with my MacBook randomly shutting down. I initially thought it was due to overheating which was logical considering I was using my MacBook in bed and the computer was very hot when it would shut off, but I've recently started using a TV-Table top for it to sit on when I'm using it in bed. My MacBook continues to shut down and the computer isn't nearly as hot as it was prior to using the TV-Table top, it is just warm. It's definitely not a battery issue because this happens when I'm using the power source as well. *I think I've noticed that this only happens when I'm in Firefox watching online streaming video on sites such as YouTube.* I never use Safari so I'm not sure if the problem would occur in Safari or not. I tried installing the MacBook SMC Firmware Update v1.1 but it said my computer didn't need it.

I have the same problem, every once in a not-so-blue moon my macbook pro shuts down while streaming video. It only happens when streaming video. Just watched some of the new south park episode, and it shut down on me! It really ticks me off!!!!!

MAC AIR SHUTS DOWN WHILE STREAMING

My MacBook Air shuts down while streaming video. I am using safari and it works for a while but then shuts down and will not restart for quite some time. When it restarts I have to immediately close the video window or it will shut down again. I have the latest version of flashplayer.

This sounds like an overheating issue. Flash requires a surprisingly high level of resources. Do you hear your fans running at all while you are playing the videos?
Download the free iStat Pro widget directly from Apple:
http://www.apple.com/downloads/dashboard/status/istatpro.html
It will show you both your fan speeds and temperature. Start playing a video and let it play for a short while (sometime before it typically shuts off... but long enough to let things warm up). Then check the temp and fan speed. Do this while the video is still playing as things can cool off pretty fast after you stop playing the video. Post the numbers back here.

MacBook Pro (Mid-2009) shuts down while running on battery

Hi,
Five months ago, my MacBook Pro 15'' (2.53Ghz) started showing me the message 'Service Battery'. I took it to an Apple Store and I was told that everything is still fine. Nevertheless, for the past 2 months my laptop shuts down while running on battery (with 20% and 40% levels of charge) periodically. This does not happen every time.
Does anyone know if AppleCare covers this failure?
Is there any other way to fix this?
Thank you,
George

Mine does the same thing. May i suggest downloading istat pro to look at the health of your battery.
http://www.apple.com/downloads/dashboard/status/istatpro.html
Also do you calibrate your battery?
http://support.apple.com/kb/HT1490
I had never done that but after 15 months and 450+ cycles I was experiencing the same problem. I am a heavy user of my mbp 15" (2.4Ghz). After calibrating my health in istat which was going between 30-53 % Is holding steady around 65-mid 70% health wise. I have also noticed that my battery icon has gone from service battery to replace now to holding at replace soon for the time being.
I am not sure how many cycles you can get out of one battery but as far as i know 700ish is good. While i wish i was closer to an apple store (3ish hrs or more) i do hope i have helped you.

IMac G5 Shuts down while running applications

I installed iLife '06.
Since then my iMac G5 (20") has started shutting down while I'm working.
I'm not sure if the installation is related to the intermittent shut down or if there is another problem.
Someone told me that the fan might be bad. I don't know how to check if the fan is bad. I've heard that some iMac's have noisy fans. I've never heard the fans on my iMac.
I've had my iMac for ten months with no problems.
iMac G5 Mac OS X (10.4.6)

There are two common reasons for an iMac G5 to shut-down:
1) a failing power supply (see the article A. Brody mentioned).
2) Over-heating.
I'll tackle the second one.
All the recent Macs have a protection mechanism built-in. If the system gets beyond a given temperature, the computer will turn itself off (without warning) to prevent permanent damage.
So, if you notice that the computer is running warm before it shuts-off, then that could be the cause.
But, it is also very likely to be the power supply.
And, operating with a faulty power supply could lead to tons of other problems or damage.
So, I would personally get it into a shop for inspection and repair very fast.
But, if it is under warranty, you should not have any trouble at all getting it fixed (either standard warranty or AppleCare).
If it's warranty has expired, see if it is within the covered systems listed in the article A. Brody gave you.
If so, request it to be inspected and repaired for free under terms of that extension.
Regardless of which problem it is, get it fixed. Neither problem is one that should be ignored.
Hope this helps.

EMac shuts down while on-line

I'm visiting relatives in Ukraine, and they have an odd problem with their eMac that I've been trying to fix. The eMac will, suddenly, with no warning, shut down while on-line. First, the windows and toolbars all disappear, leaving only the desktop photo. Then, seconds later, that disappears, too, and the computer shuts off.
This seems to happen only while using Gmail or Yahoo mail; earthlink web mail hasn't triggered it. (And I haven't tried any other web mail sites.)
Any suggestions?
SO far I have:
repaired disk permissions
verified the disk
run the Apple hardware test
upgraded to 10.4.10
installed iLife '08
installed and tried Firefox
Thanks.

Good idea, trying the test user! That the test user ran OK helps narrow done the troubleshooting steps, although it still leaves a lot of open questions.
The flashing question mark followed by eventual starting indicates that the startup disk PRAM setting is lost or corrupted. Open System Preferences -> Startup Disk and reset the startup volume to be the hard drive's OS X volume.
The missing hard drive in Disk Utility sounds bad, but if the hard drive were corrupted, it shouldn't be starting up and your test user account shouldn't be running. If you're braver than I am, you can try remotely talking your family through using the Unix file system check utility as described in Using Disk Utility and fsck.
That the test user you created had no problems would seem point to either a conflicting third-party add-on, or a damaged hard drive that's being triggered when Spotlight runs in the background. The latter is unlikely since your test account ran OK. Have your family try Starting Up in Safe Mode. If the Mac is stable in Safe Mode, that leaves the process of determining what third-party add-on is causing the problem (talking someone through that sort of process remotely gives one a whole different perspective on the life of call center tech support staff).
The basic idea is to move items out of the /Library/StartupItems and /Library/PreferencePanes folders and into a holding folder, retarting the computer, and seeing if the Mac is stable or not. After a particular item is identified as a likely culprit, it can either be deleted or, if the particualr function is really needed, the publisher's website checked for updates.
Good luck!

Iphone 4S: Shuts down while charging

My brand new 4S shuts down and starts up every 5 minutes while charging. Batteryindicator is also stuck but is updated after the device is rebooted. Suggestions? Scrap it, wait for software updates or ship it for repair?

It went from bad to worse. After a reset it shuts down and starts up continously even without the chargingcabel connected, until it is turned off by the slider and started again. Nothing changed to the battery indicator either.
It is now returned to the dealer for repair.

Does shutting down and starting up wear out the hard drive faster?

does anyone know if shutting down and starting up the imac repeatedly wear out the hard drive faster? I had heard that repeated shutting down and starting up of the hard drive will wear out the hard drive faster. If this is true, is it better to put the imac to sleep and shut down only when you absolutely have to or when you will be gone for a while? (e.g., going on vacation or when moving the imac). The imac manual suggests that if you are going to use the imac within a few days to put it to sleep and shut it down if you are not going to use it for a few days. Is this advice just to save you time since you don't have to reboot or will this help prolong the life of the hard drive? Of course, keeping the imac on all the time might waste energy (not sure if sleep mode saves energy). But since I use the imac practically everyday it may make sense to put it to sleep, especially if this will prolong the life of the hard drive. thanks

Good Morning,
In my experience there shouldn't be any unnecessary wear and tear on your hard drive from shutting down your computer unless you are doing an EXTREME amount of startup/shutdown cycles.
The average user should not put enough strain on the drive to even be noticed from normal startup/shutdown cycles.
Hope this helps! 

Potential Args, Computer shutting down while playing a game

I've only had this mac for 5 months, but it keeps shutting down while I'm playing StarCraft II. It should be able to handle the game, but it keeps telling me to restart and I have no idea what the error says or means. I'm not sure what (4 potential args on stack) means. I'm not sure if it is a frame rate issue and how to fix it or change the frame rate if needed. Any help would be much appreciated. The error is below:

You are only just beginning to feel the pain of Starcraft II on your Mac. Have you seen this List of problems?
Blizzard created the junk, and it's up to them to properly patch it. The list of other well known and respected programs it's incompatible with (LittleSnitch, AppCleaner, FileVault, and PeerGuardian to name a few) doesn't give me a warm and fuzzy.
The page also mentions that your CPU can overheat, for whatever reason, and that means total failure for a laptop or early component damage to a motherboard. Gee, that sounds like something that shouldn't be run on a regular basis.

Power Mac G4 Shuts down at start up

Hello,
I have a power mac g4 that Shuts down at start up. It will get to the white screen with the apple for about a minute and then shut itself down. I tried starting up from a disk and it doesn't even get that far.I haven't replaced any parts yet but I was wondering if it may be a problem with the computer's power supply. Any suggestions are appreciated, Thanks

You may need to reset the logic board. If you open the side of the G4, you should be able to find the reset switch.
Unplugging it first would be a good idea.
