IMac G5 shuts down while importing HDV video in iMovie

So here is the problem, my 20" iMac G5 will be importing video from my Sony HDV camera, and will just shut down. I mean turn off completely. It happened 6 times yesterday to my wife. When I try to turn it back on, sometimes it will work, sometimes, I have to unplug the iMac from the plug and wait 30seconds before it will turn on again. Any one have any experience with this? Is it a power supply issue? Any thoughts would be greatly appreciated

got apple care to replace power supply

My imac suddenly shuts down while on line.

My imac suddenly shuts down while on line. It has to be unpluged for a couple of hours before it will restart. Could it be the battery dying? Any other sugestions?

Which iMac..? Go to > How to identify iMac models
1. Reset the SMC > Intel-based Macs: Resetting the System Management Controller (SMC)
2. Reset the PRAM and NVRAM > Resetting your Mac's PRAM and NVRAM
Then test it for a time and report back.
You also might want to give the Extended Apple Hardware Test a run, as per > Intel-based Macs: Using Apple Hardware Test to see if it turns up a hardware 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!!!!!

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.

IMac G5 shuts down while installing software

My G5 iMac 3yrs old Os 10.4.11? while installing iLife'08 comp shut down. Restarted, tried install again,shut down. Progress bar shows 28% complete at shut down. Same problem with iWork '08. Three times in succession.Any ideas?.............Rich

Try booting from your install disc, run verify/repair drive from Disk Utility and see what it says. Then, reboot and repair permissions while booted from your hard drive.

Computer shuts down while importing

This doesn’t happen with every song I try to import in iTunes, but let’s say with 2 out of 10 songs, while importing my computer simply shuts down. Just before it dies on me it says something like: Error, disk locked. I just can’t figure out what’s his problem.
Hp Pavilion dv1000 Windows XP

Problem solved for me... I changed the place of my computer which seem to have helped. I think the problem was heat... too much heat and now I can import a full CD without my computer to shut down. If it is not heat, I read that it could be bad memory. if my computer shuts down again, I will check the memory of my computer.

Windows shuts down while importing CDs

Please help!
I purchased my iPod 30 Gig Video about two weeks ago. I have a Windows XP Home SP2 computer. When I’m importing CDs Windows shuts down the computer and dumps the physical memory. This happens when I usually put in the second CD. Here are the specs of my computer:
AMD Athlon XP 2800+
2.08 GHz, 1.00 GB of RAM
I have a Memorex DVD 16+/-DL4RWD2 DVD/CD-ROM drive
For my virus protection I’m using Trend Micro PC-cillin Internet Security2006
When the problem first started I uninstalled and reinstalled the iTunes/iPod software. I made sure that all of the previous versions of iTunes and Quicktime were deleted. When I reinstalled I turned off my virus protection.
Lately when I’ve come across this problem I turn off the virus protection thinking that that might have something to do with it.
I have all the current Windows updates and the drivers for all of my hardware is also current. I don’t know if my virus protection is causing many problems (i.e. firewall, etc.) Can someone please help?
Thanks.

Your's isn't a dual processor (or simulated dual processor, aka, hyperthreaded) machine, is it? I and many others have found this problem to occur on such machines (when is Apple going to fix this problem?) Some have found forcing iTunes to run on only one processor to be a successful workaround (there are at least a couple freeware utilities out there (I don't recall their names OTTOMH) that will force a PC app to run on only one processor on multi-processor machines, or you can try, after starting iTunes up, cntr-alt-deleting and selecting Task Manager, then in the list of running apps, right-click on iTunes and choose Go To Process, then right-click on the selected process and select Set Affinity, and uncheck one (or all but one if you happen to have more than two processors) of the boxes) but this didn't work for me: I had to physically remove one of my two processors - I haven't had the problem since, so I'm confident that was (is) the problem in my case. (But I'm still ****** 'cause I very purposefully bought a dual processor machine; it just so happens that right now I'm doing more CD importing than dual core work, so for now it's the best solution for me, but I eagerly await the day I hear that Apple has FIXED THIS PROBLEM!)

Iphoto unexpectedly shuts down while importing photos

Recently iphoto has been shutting down every time i try to import photos from my camera. i originally thought that it was a problem with my CF card but i tried uploading with a new one and als an SD card but i have had the same problem. ANyone haveing the same problem, any ideas how to fix it? i am using v6.06.

TimmyW
Welcome to the Apple Discussions.
Ensure that you have the latest version of the OS (10.4.10), Quicktime (7.1.6) and the app.
1. Repair Permissions using Disk Utility
2. Delete the com.apple.iPhoto.plist file from the home / library / preferences folder. You'll need to reset your User options afterwards.
3. Create a new account (systempreferences -> accounts) and see if the problem is repeated there. If it is, then a re-install of the app might be indicated. If it's not, then it's likely the app is okay and the problem is something in the main account.
4. Are there movies on these cards as well as photos?

IMac keeps shutting down while in sleep

I have an iMac G-5 without iSight.......not sure if this started happening after the last sucurity update or installing HP printer software, but now when the computer goes into sleep, it waits awhile and then shuts down entirely, forcing me to turn the computer back on. I uninstalled the HP software, and repaired permissions, but this still keeps happening. Any ideas on what caused this and what I can do to fix it?
iMac G-5 Mac OS X (10.3.9) 80 gig hardrive which has about 2 gigs left

Hi,
I am having a similar problem. I have an iMAC (serial in the range W8435xxxxxx - W8522xxxxxx) and in the two weeks, when the computer is put to sleep it turns off. However, I only notice this in the morning after it has been asleep all night. The problem seems to be far more frequent when I put it to sleep as opposed to just letting it time out and go to sleep that way.
I have applied all updates and the only modification to the computer is extra ram (from Other World Computing).
I have seen elsewhere that I can see the computer's reason for shutdown in "system.log". Can anyone tell me how to find that so I can look for the shutdown code there?
Any ideas?

Computer shuts down while importing audio cds?

When I am on the 4th or 5th song, mu computer justs shuts down? Any ideas?
Jenn

are you getting any sort of blue screen, Jenn? if so, what numerical and text codes are you getting with it? (ie 0x[zeros/letters/numbers] CAPSANDUNDERSCORES)
if the blue screen mentions a specific file, let us know what that is called too. (exact spelling, please.)
here's a reference on the sorts of things i'm asking about:
Troubleshooting Windows Stop Messages
if you're not seeing a blue screen (or just a flash of one), we can use this technique to make hidden blue screens appear for us:
1) Open your system control panel (Start->Control Panels->System).
2) Select the "Advanced" tab.
3) Click the "Startup and Recover" section's "Settings" button
4) Verify that under "System Failure" the "Automatically restart" checkbox is not checked.

IMac completely shuts down while working in LR4

I have an iMac 27 2.9ghz 12gigs ram with a large file of photos (13000+) My computer shuts completely down witha sudden "pop" when working in LR4 only. Had iMac checked at genuis desk an they put a new powersupply in....but still does the same thing...Is it the program LR4.2 or my computer?

Sorry, this is clearly a hardware issue...LR 4 does (as Victoria mentions) "stress" the CPU. But f you are hearing a "pop" then something is seriously wrong with your hardware (a "pop" indicates that your power supply is toast) your hardware should NOT be making noises...when it does, you really need to look out!

Imac randomly shuts down while idle

I have a new imac 27". Purchased early Sept. about three times in that space I have come to use it finding it shut off. I leave it on sleep all the time.
Could I need a new UPS.? It is about three years old.
The console report shows it is looking for something but I don't think that has any bearing on the problem. Once it is up and running, no problems.
This is the console message:
"11/6/10 12:49:23 PM ..ButtonManager(164) Looking for devices matching vendor ID=1193 and product IDj=8717"

Thanks. I just realized that something else seems to be going on here. I have two printers attached to the computer, an HP 6150 all in one and an Epson R1900. I just noticed that the HP was also off. It is not plugged into the UPS but a different strip. I unplugged it and plugged back in and it came back on. Is it possible that somehow the printer is sending some kind of signal to the computer and shutting it down??? Sounds weird but maybe there is a problem with the printer. Maybe I will unhook the printer from the computer and see if that helps. It is so random and happens so seldom that it will be hard to know.
Thanks

Why does iphoto6 shut down while importing pictures?

This happens when I import IMG_xxxx.jpg pictures from the desktop, documents folder. iPhoto shows the same problem when opening IMG_xxxx.jpg pictures that already exist in the library.
This has been happenning since the latest update to iphoto.

Aperture shut down during import

I started the import of photos from iPhoto to Aperture. Aperture shut down in the process. How do I upload only the photos that did not transfer? I tried import again, but it appears to want to upload the entire library again..

Have you done any work in the Aperture Library? If not, just delete it and redo the import into a new Library.
This may be a good idea anyway, until you determine what caused Aperture to shut down during the last import. Aperture allows you to easily merge Libraries.
Make a back-up of your iPhoto data first -- after confirming that nothing was harmed when Aperture shut down while importing.
Also, if you haven't upgraded your OS to the current version (you have 10.7.1 listed), you should.

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?
