My computer keeps shutting down.

My computer keeps shutting down. It just goes black. To turn it back on, I have to wait a few minutes before pressing the button. When it comes back on, it seems to take longer than usual. It seems more likely to do this when I have several programs running at once. There might be a flickering light on the lower right side.
It's a desktop computer.
Any guesses?

I had a similar, but different problem. My iMac running OS 10.5.6 wouldn't start up all the way. I would get the Apple logo and the spike gear on the grey screen, and after a while the computer would go off (black screen). I started from the install disk and got horrifying red messages that disk utility couldn't fix it. AIEEEEE! I bought Disk Warrior, and fearfully rebuilt the disk directory. Problem solved.
Strangely, neither my Apple store nor a large electronics store carried Disk Warrior. Nobody at the stores knew why, although they said they had lots of inquiries about it. Third try I found DW version 4.1.1. Problem solved.

Sounds like you'll need to access that drive while it is not booted. You need to replace it anyway, so do that, then one way or another (ext enclusure, et), access it and copy files.
If you keep trying to boot it, you might kill it for good and not get your files, so just swap it out first.

Sounds like you may have hard drive issues.
You can try using built in diagnostics if you have them by holding D on startup. If nothing special happens, your model does not have them. You can then try to boot to recovery by holding Option while starting up and selecting Recovery HD. (Run Disk Utility Repair) If no Recovery HD appears, then you have a bad hard drive or an older OS than supports it.
If neither of those works I'd take it to an Apple store or Authorized Apple Service Provider near you for a diagnostic test. Apple will do it for free, so it's preferred for a test, but may not be the best price for a simple hard drive replacement. Head over to locate.apple.com to find the nearest AASPs and Apple Stores and set up an appointment.

My computer keeps shutting down and I don't know what to do.

I purchased the student/ teacher version of the cloud membership/ design suite for os x and promptly began downloading the programs that I would use onto my macbook pro. I downloaded photoshop cs6, Bridge, Illustrator, and Acrabat. I havn't used anything but photoshop so far but I have encountered a serious problem. When I first got photoshop I would leave the application open by accedent and my computer started shutting down randomly but only about once a day. As I started using photoshop more I started closing the application when I wasn't using it but when I was the computer would shut down at some point during each project. I could deal with saving a lot as I go but now it shuts emediately every time so I can't use photoshop at all. Please can someone give me some advice, even if it is just to go to the apple store.

I had very similar behaviour occur when I purchased my first MacBrook Pro and it turned out to be a faulty Graphics Card. Take it to the Genius Bar and see what they have to say. If they don't know what's going and it's not a hardware issue, then we need to know a lot more to help you.

Computer keeps shutting down

I've had my G5 for about five years now and have had a few other issues with it, but most of them were very easy to fix.
Unfortunately it has recently begun to shut down five minutes after it's turned on, which has never happened to me before. I use this computer for work, and I'm not really in a position to spend a lot of money to get it fixed right now.
Is there any way that I can figure out what's wrong with it? The CD drive has been broken for awhile and just spits them back out, so I am unable to un-install/re-install anything that way.

It's almost certainly not a software problem. Possibly a thermal shutdown from overheating, so definitely start by cleaning the vents, but this is not likely. Usual cause is bad, bulging or leaking capacitors on the Logic Board or the power supply. Unfortunately, a very common issue on these models (mostly non-iSight.) You will find almost every other post here may involve this problem.
Remove the rear cover by loosening the three captive screws; only loosen them enough to free the cover. Inspect the caps on the board; they look like little soda cans. Make sure the tops are perfectly flat, nothing leaking. You won't be able to peek inside the power supply easily.
If you find you have this problem and if you search this forum, you will find many threads with recommendations about how to proceed.

HAMitch,
your EtreCheck report will not reveal why your MacBook Pro shuts down randomly. What this report does reveal is that you have out-of-date versions of Java and Silverlight installed. The latest version of Java (7, Update 55) can be downloaded from here, and the latest version of Silverlight (5.1.30317.0) can be downloaded from here.
Without knowing some example situations in which your MacBook Pro randomly shuts down, it will be difficult to diagnose the problem. Would you provide some examples during which it has shut down? That is, which programs are running when it happens? How long has it been booted up when it happens? &c.
In the interim, after updating Java and Silverlight, you can try running your MacBook Pro’s Apple Hardware Test, to see if it can detect any hardware problems.

After downloading mountain lion my computer keeps shutting down and restarting, why? this never happened before

Why is this happening and should I uninstall mountain lion? It has restarted more than 10 times since I installed mountain lion yesterday

Hi Barney -
Here is what the report says after it restarts...I took it to the genius bar they ran a test and said all was fine but it is still shutting down and restarting constantly!

Computer keeps shutting down after installing yosemite

my laptop started randomly shutting down with an error after i installed yosemite does anyone have any suggestions?

The next time the problem happens, note the date and time the problem occurred, then go to Applications/Utilities/Console and copy the log starting at the time of the crash. Paste the log in a reply. Please do not use a screen shot as they can be hard to read. If there are repeated runs of the same messages, please post only one run. Be selective about what you post and don’t post huge amounts.

Computer keeps shutting down when trying to update Thunderbolt Firmware Update 1.2! But says I have installed it 4 times already.

Hello All,
Today I updated my MacBook Pro Early 2011 from Lion to Mavericks. I then went onto my App Store and it says I have an update that I need to install. This update is the Thunderbolt Firmware Update 1.2. Everytime I press update, it says that it is downloading, but suddenly my computer just turns off with no warning when the download hasnt even started. I'm worried that this will damage my computer! What I don't understand is that App Store says that I have already installed this update 4 times. But if so, why is it still saying that I need to update it?
Any help will be most appreciated!
Celine

Unfortunately after that I have no other suggestions... if it was my computer I would reformat the entire computer but you need a good backup to do that something is obviously corrupt and not acting right otherwise if you have another computer that you can use to update..

My Computer Keeps Shutting Down... HELP.

can anybody help me? my computer is fairly new. i have an i mac i bought at best buy and nobody on this earth seems to have a clue what is happening. after about 10-30 minutes of using the computer everything connected to my computer just goes black. it's connected to a surge protection outlet and everything else plugged into the outlet seems to be continually working. but after a short time my computer just goes black and i have to wait a long time after unplugging everything in the back... then plug it back in and usually it starts back up and then goes black again... it is an annoying never ending cycle and nobody so far has a clue what is happening... PLEASE SOMEBODY HELP US... we are computer challenged. thank-you.
rhea and eric

Which mac do you have?
I had the exact problem on my 2 year old G5. It was serviced 5 times by the apple store geniuses. The power source was replaced 3 times, the motherboard once, and something else done.
They resolved this finally, after the 5th repair, by giving me a new G5 (on the eve of the new models being introduced a few months ago - must have had a few of the older ones in the back room <G>).
Anyway, it was only at that visit that the genius acknowledged a power source problem on the G5's.
So if you have a G5, ask specifically if it could be that known problem.

My computer keeps shutting down by itself

Hi, I have a HP desktop PC. I runs great but in the last couple of days it seems to have a mind of it's own.
While your on it or off it, it only stays on for maybe 5 -10 minutes. Then it restarts by itself. Does anyone
know what could be causing this. I have checked all the settings and everything seems OK. Can someone help?

I've always had good luck just cleaning out the fan areas with compressed air.
