IMac :: No Warning - Just Shuts Off - Overheating?

Sep 14, 2009

I've been having trouble with my new iMac that i purchased recently (26th of August actually). Whenever I'm doing something CPU intensive, the machine just shuts off, but usually it's not right in the middle of whatever I'm doing, it's after I close the application. For example: I was playing SimCity4 the other day, pretty old game to cause this problem I would think. As soon as I exit the game, the system shuts off. No warning, nothing, just shuts off. This will happen when i close VMs (it actually happened yesterday while I was running the VM), etc. So I've reset the SMC/PMU, PRAM/NVRAM, and I've even reseated the RAM. Still the same problem. I've taken it in to a repair center in town, hoping I'll get it back by the end of the week. Does anyone have any idea why this would be happening?

Mac Pro :: Under Desk - Overheating - System Shuts Down

Aug 10, 2010

So I am about to order a 2010 Mac Pro. I am looking for opinions from users who own or have owned any recent model (last 2 years) Mac Pro in terms of how much heat they throw off and how much open air space they need. The reason I ask is my custom desk at home has one of those wooden "compartments" that a tower or workstation computer can slide into. If I put the Mac Pro in there, it will be exposed on the front, but the top and all sides will be surrounded. I am sure you have all seen the type of desk slot I am talking about. Its a bit like putting your mac pro in a coffin. with only one side open. do you think this will be a major problem and cause overheating? Or result in the Mac Pro shutting down? If so do you have any suggestions because my desk area does not have any open room for the computer stand with all open air around it.

MacBook :: Overheating And Slowing Down - How To Make Fast And Prevent Overheating

Oct 1, 2009

I have a new macbook, see stats below.

Up till last week everything was fine, I could run 'Second Life', photoshop, email, a browser, download stuff, play Itunes AND watch a movie all at once without any trouble.

But recently the computer has gone a bit weird.

It started getting very hot, much slower and turning itself off.

Hardware :: Computer Shuts Off Unexpectedly?

Jul 29, 2010

I have a strange problem with my late-2008/early-2009 MBP. In the last couple of days, I have been using it and the screen goes black suddenly. It happened once for just a few seconds and then recovered, but today it completely shut off-- even though the battery was mostly charged (and I had received no warnings)-- so I had to reboot.

A few possibly relevant facts about this computer and this incident:

1) I've had it over a year and never had this problem before.

2) I had the logic board replaced recently because of an issue with sleep mode. This problem never appeared before the logic board was replaced (although this may be a coincidence).

3) Both times the problem happened this week, the computer was running on battery power.

4) Earlier this week (before the incident), I got a little warning to "Check battery" or something similar. The warning went away, though. Maybe this is a faulty battery issue?

5) When the computer completely shut off, it was also running a Time Machine backup. I noticed that TM has been having trouble today-- giving warnings about errors. Not sure if this could be related.

OS X Server :: Computer Shuts Down - Right After Start Up

Feb 25, 2008

My comp. has worked perfectly, Then I installed some updates, Itunes i think? And the comp. Shut down, and when it restarts it works for a min or two, then freezes, and i get the beach ball, that just spins around and around forever.

if I don't try to open anything, or do anything when i restart it, it will just shut down, and restart, then when it comes to the Grey screen with the apple and the little circle below it, the circle looks all pixilated, and just freezes

that is the version its on (Taken two days ago, and sent to a buddy for other reasons completely)

MacBook Pro :: Computer Turns On For Half Second Then Shuts Off

Sep 3, 2010

Macbook pro intel core duo. My macbook is turned off, when I press the power button the light goes on and the computer starts making sounds of turning on for about half a second and than shuts off. I tried removing the battery and putting it again, I tried to hold the power button (the light flickers at one point and eventually shuts off as well after 2 seconds), and tried turning it on with the adapter plugged in and unplugged.

Software :: Computer Shuts Down After A Minute Of Inactivity

Jan 10, 2010

After just over one minute of inactivity (no moving mouse, typing, etc.), I get a "Logout, Cancel, Restart, Shutdown" screen. If I don't quickly click out of it, the computer totally shuts down. I have an Intel Macbook. I don't believe it's a hardware problem; I've run the hardware test and it comes up clear.

Nov 1, 2009

I've got a four year old Macbook Pro 17", running 10.5.8 OSC, 2.33 ghz, 3gb 667 mhz ddr2 sdram.

The power cord was unplugged, although the battery was fully charged. I plugged in my Canon printer for the first time in over a year. It printed half a document, then the computer shut down. I pushed the power button and got the start up chord, but then it shut down again. Tried this a few times. Then I unplugged the printer and plugged in the power chord. it started, but it's very slow, and I keep getting the pinwheel.

MacBook Pro :: GPU Panic Error - Computer Frequently Shuts Down

Jul 1, 2014

Recently my MBP retina late 2012 started crashing with the screen going all black leaving the keyboard lights on. I had to force it to restart. After a couple of attempts I could finally access the computer for about 10 min before it crashed again, during which i could see the logs. As of know it has been on for 1 hour without any issues but when I run some more hardware-intense programs it crashes. Since i bought the computer from a private person without insurance im not entitled to the 3 year warranty. 

Im getting these errors:

MacBook Pro :: Gray Progress Bar Starts And Then Computer Shuts Off

Aug 27, 2014

My MacBook Pro will not start. It chimes and the gray progress bar starts and then the computer shuts off. I am able to start it holding the Command +R keys and access Disk Utility. That is where it says my S.M.A.R.T. drive is "failing". I have a backup from Time Machine from a week ago. I am concerned the computer is going to die. What should I do and is my computer going to die?.

IMac (Intel) :: Desktop Fan Comes On And Then Screen Goes Black Shuts Computer Down Every 5 Seconds

Jun 4, 2014

I have a 27 inch desktop. Upon turning the computer on within seconds the fan comes on. Then it goes to a high fan. Then it goes to a black screen. Then it shuts off. Then if you click the mouse it will come back on. This cycle repeats itself every 5 seconds. Only one time in the past month did it turn on normally and run for me.

MacBook :: Unable To Use System With Battery / Computer Shuts Down Hwen Start From Battery

Apr 18, 2008

My battery needed replacing for a couple of months before i dropped it from about knee level onto a sidewalk. After the drop I got the not charging icon. I thought maybe the battery had just finally died. so I did not panic about the no charge. The laptop works fine when plugged in to power with the old battery on or no battery at all. Not at all when unplugged.

When I put the brand new battery on the lap top, the computer shuts down halfway through boot up. I tried holding the power button down through boot up reset, as well as removing all power (plug and battery) and holding down the power button for 10 seconds reset.

OS X :: MBP Overheating Due To Flash?

Apr 2, 2010

Before I start, here are my late-08 MBP stats:
2.5GHz C2D
512MB 8600 GT

OK, with those relevant stats out of the way, my MBP will usually sit anywhere from 120-125 F just browsing with iTunes playing in the background, Mail open and maybe Parallels. However, I after letting my sister use my computer and her going on Farmville in Facebook, I noticed it was running up around 140-150 and a couple times reached 160-163 (these numbers are via two different temp apps).

When I looked, there were 3 flash programs going on...two pop-ups for a seedy cam site and Farmville. Closed the two pop-ups and the temps dropped back to 147-150. Once Farmville was closed, temps went back to normal. My question is it normal for flash applications to make the laptop run so hot? Is there some sort of update I might need?

MacBook Pro :: Overheating Before Booting

Oct 20, 2010

What could possibly make a macbook pro overheat before it is even booted? I have bootcamp installed so I can run solidworks and a few misc programs in XP. The machine always runs a bit toasty for my liking under windows so I use smc fan control to crank the fan and then reboot into XP pro. This works great as long as I dont need to sleep the computer and re-open later. In this situation the fans dont resume the higher speed I specified and I get temps in the 70-80C range.Thats not really the problem though. Today I started the machine (from a complete shutdown) and held option to bring up the bootcamp chooser. Meanwhile I was distracted with something at work so the computer sat like this for 15 minutes. No OS had booted, just the gray chooser screen. When I came back the fans were running full blast! The overheat protection had come on. I quickly booted into snowleopard and the temps were in the high 80-low 90's. After a minute it was back to normal 50's but I'm puzzled. All software is up to date.Nothing was even running?!? How is this possible? Nothing should have been straining the system.

PowerPC :: Mac G5 Shutting Down - Overheating?

Nov 27, 2010

I've got an early 2005 model Power Mac G5. Bought it from a hospital and it's really clean inside. Lately it's been shutting down spontaneously without warning. I thought it might be an issue with overheating, but I'm not that familiar with normal heat levels for a CPU. I installed iStat nano and checked the temperatures. I took a screen shot of the widget. Temperatures are in Fahrenheit. Can anyone tell me if I'm on the right track? What do I need to do to solve this problem?

MacBook Pro :: Overheating - How To Cool Down

Jan 5, 2008

I have a 2.0 macbook with 2g ram 80gb harddrive with 29gb free. My problem is that my macbook runs idle at around 130-140 degrees fahrenheit. When I go to Youtube it goes up to around 160 degrees and when I go to Google Books and open up a page my macbook reaches around 180 degrees I also do a lot of audio production and temperatures reach a steady 165-180 if I have a fair bit of processing going on.

What the hell is going on? I need to use google books for school and don't think it is safe to use my MB at such high temps. Also with all of the audio work I do I imagine that the lifespan of this computer will not last very long.
