IMac :: Freezes After 15 Minutes Of Being On - Overheating?
Aug 21, 2009
My Imac freezes up a lot, usually after 10 to 15 minutes of being on. I suspect it has something to do with overheating. I have to get my data off of the drive before I take it into the Apple store for fear that they will will just replace the drive and all will be lost. I have a fan blowing on it now in the back and am copying data onto an external drive little by little until it freezes up.
I bought it last fall and have a 3 year warranty on it and this will be my second time bringing it in for repair. The first time it was a problem right out of the box when I brought it home and it was replaced. It's a 3.06 processor, 24 inch screen. I am not impressed by the hardware reliability and the all in one system. I am regretting buying the imac after being a PC user for so long and I am using my Windows PC to write this. I suspect the cooling system could be better on my IMAC given the compressed footprint.

This is my first Mac user problem posting going back to my original SE! Power PC based imac running leopard 10.5.8 starts up but then mouse freezes after a few mins. Managed to change sleep mode to 15mins - same problem. Can't boot from Disk as same problem, also command+option and shift all still have mouse unmoved! Obvious change of keyboard and mouse have no effect. Could this be related to offspring's addition of ipad plugged into usb a few weeks back? He tends to unplug the device without ejecting!

Over the last few months I've noticed a trend with my dual 2GHz G5 at home, it often locks up and the fans go full-throttle. It sometimes happens when I'm using it and often when I leave it idling for a while. I've noticed that the CPU A and CPU B temperatures start around 120 degrees F when the machine is first powered up and steadily climbs to around 150. Is that normal? The dual 1.8GHz G5 I have at the office doesn't run hotter than 110 degrees. The fans haven't failed. Is there a coolant link? Is there anything I can do to diagnose this, or do I simply need to call AppleCare?

My computer, a Powermac G5, Dual 2.0Ghz, 1st Edition Released Oct 2003, will just freeze. It usually happens within 5 minutes of booting into the operating system. I am also unable to boot from the Leopard or Tiger DVD's to try and install a fresh copy of the OS as they freeze during the install. This is what I have tried so far, but to no avail:
Resetting the RAM and Graphics Card
Resetting the Power Management (PMU)
Resetting the PRAM
Now this is the even stranger thing. I installed a copy of PowerPC Ubuntu Linux 8.04 and it works fine. This makes me think that it is unlikely to be a hardware issue.

When I start up my computer everything looks normal, all icons are on the desktop and my cursor is able to move. The problem is I can't affect any of the icons on the desktop (folders, files, etc)-every thing is frozen. After about 3 minutes it unfreezes and everything then works. what is the problem?

I just purchased my mac book pro on the 18th of may from an apple store, brand new. I decided to upgrade the RAM myself since it is a much better deal, however once I replaced the RAM my computer began to run much slower and it began crashing (showing a gray window that says "please restart your computer" in many different languages) so i restarted my computer and the problem continues, after 12min of running that window appears. I replaced the RAM with the original and the problem still continued. I have run normal hardware tests and extended hardware tests as well as PRAM reset and still nothing changed. Does anyone have any idea what is going on? I'm totally lost on what is going on with my brandnew macbook pro!I should also add, I have been running the extended hardware test multiple times to see if it will crash during that and after 1hr it hasnt crashed yet.

My Macbook with 4 gb RAM won't boot standard, safe, or Recovery.. All three results in grey screen with apple logo and spinning wheel which freezes after a few minutes. It also won't boot a bootable Mavericks usb with install package. I can boot single user mode and also view whats going on in verbose.. I am including a photo of where the script stops. PS: I've already tried resetting PRAM and the SMC has been reset as well.

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.

iMac is been in on the repair bench more times than I can count. Luckily, most of it was under warranty. But I was just wondering, if anyone here's got the same system (or knows someone that does) and has 'modded' it to run cooler?

I got an iMac i5 recently, and I've downloaded iStat. It seems as though the HD hovers around 55C, and I think 60C is the maximum. Are there any precautions I should take, or is there nothing to worry about?

I don't know if it is a fan or a drive that starts up and runs really fast and loud, then the computer shuts off. I always thought it was the fan, but now am not sure. I have moved it to a place where it is exposed to more air, but that has not seemed to help. Does anyone have an idea or solution to this problem? The nearest Mac dealer is about 80 miles away, so if I can fix this on my own, I would like to try.

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?

Yesterday a friend gave me a really nice 17" iMac G4 he was planning to throw out because it was having problems. I would really like to get this working and would potentially be willing to buy parts to repair it. I have a significant amount of Apple hardware experience, but would like to get the opinions of people who may be more familiar with iMacs than myself on these forums. The problem is that the computer has random kernel panics. Sometimes it occurs as soon as the computer is turned on, sometimes after it has been on for a few minutes, sometimes after a few hours. So far, I have replaced the RAM with known good sticks, have replaced the hard drive with a tested good one from my collection (and these were both upgrades to boot!) and I have re-applied thermal paste (Arctic Silver) to all key components (CPU, ends of heatpipe, GPU) but to no avail, I still have the same problem.

I was using my Imac G5 (pre iSight) and it suddenly shut down. It smelled of burnt plastic so I immediately disconnected the power and all accessories, laid the computer down, and took off the cover. Everything seemed normal, except the smell of burnt plastic coming from the fan and faintly from the power supply. I took the metal piece covering the fan and hard drive, and attempted to clean the fan. After about an hour I put the cover back on, plugged my computer back in, and started it up. It again shut down after about half an hour of use. What's wrong? Do I need a new power supply? I checked the Apple Recall and my serial fits, but the symptoms do not follow the ones in the recall.

I have brought a new iMac 27'' the i5 model. I have noticed that the fans never change speed no matter how hot my processor gets ? Is this normal ? I have ran prime 95 and istat pro to check the temps and fan speeds. Nothing changes apart from the temperature.

Ive had my Imac for about 9 months and havnt had any issues with it until the past 2 months. The first issue was that i would leave it running for the day and i would restart and get the flashing folder issue. I would then go through all the appropriate steps- unplugging from the power source for 45 seconds +, try booting it with the OSX cd in, ect. At first these steps worked. The next issue i had was a power outage. I followed the same procedure when i went to start my imac up again (mind you it was within 10-15 minutes of it being turned off) and these steps did nothing and the flashing question marked folder appeared every time. I called Apple support and after 2 hours they insisted that it was a faulty hard drive. I let the imac sit for the rest of the day and before i went to bed i decided to give it one more shot. It booted up just fine.
Ive come to the conclusion that im only getting the boot error when it has been running for long periods of time and that the casing feels hot when i try restart. I was wondering if you guys could let me know if my theory of over heating causing the boot error is correct, and if so is there anything i can do myself to help correct the problem? I really want to avoid going to a mac store because its so far away from my location.

I have an iMac G5 that is starting up, then working okay for 1-2 minutes. After that, the processor usage goes way up, and the fans start spinning loudly. It's a first generation 1.8 GHz with a 17" display. Mac OS X Leopard. Recently, it spun up and then shut down and wouldn't start again. The room it's in is < 75 degrees F. No malodor, or other symptoms save for hot to the touch. Has been left shut off and unplugged for a few hours, and still has this problem.

For about a week now, every time I boot my iMac mid-2007 20" running 10.6.3 I get the following problems
-Booting takes about 15 minutes of seeing the apple logo, and a bar that fills slowly under it...
-When it finally boots all the dock icons are reset to the ones you get with a brand new mac, spaces and expose is reset as well.
-Spotlight reindexes Macintosh HD.
-Adium loses all contact icons
-Mouse loses all it's custom settings.
-Login items are gone, I have tried not to re-enable those.
-Shut down takes about 10 minutes as well, while I see only the blue screen of shut down...
It seems that it is losing more and more settings every day. Today I had to turn on time machine again, although it was on before shut down...
Is this like losing an application support folder or something like that?
Applications do not seem intact as well.
Safari loses all web screenshots from cover flow iTunes reupdates the library etc....
What's up witn all these?

Ive just recently bought a 27 inch imac and having problems with the sound. when i want to play something like music or a dvd it takes about 15 minutes before the built in speakers will kick in.
Has this happened to anyone else? if so have you found the solution to get around it? as apple technical support cant seem to help me with the general settings and audio MIDI set up

I updated my late 2012 27" iMac from the latest Mavericks to Yosemite. now it takes 30+ second between mouse click and action. For example, if I click on iTunes it takes 30 seconds to a minute before iTunes opens. I get the pinwheel while waiting. I rebooted and the startup hangs on the progress bar for several minutes, then black screen for several minutes, then eventually gets to desktop.

My iMac takes 3 minutes after logging in, until it allows any inputs. Stays stuck on the desktop, none of the hot corners work, nor does the dock allow inputs for about 3 minutes. I checked the Console immediately after it allows me to, and theres a bunch of stuff on the IOkit that seems to be the culprit.

Every since I upgraded my OS to 10.9, my performance has been going downhill. Now, even though I have reformatted my hard drive and have not even put any new data on it, it takes 45 minutes to restart and 25 minutes for me to open the window to write this message. Below is my system info. Why my system seems to have slowed down so much. You can see there is nothing on the hard drive to slow it down.

I have a mid 2011 27" iMac that is taking longer than 3 minutes to boot. I've tried turning off everything in the start up menu, but that hasn't worked. In one of the other questions like this, Linc, I believe said to go to terminal and post to questions the output showed up in Text edit, and I have posted them below:
Step 1:
Loaded kernel extensions:
com.logmein.driver.LogMeInSoundDriver (1.0.3)
Loaded user agents:
net.culater.SIMBL.Agent
com.seagate.SeagateStorageGauge.plist

I have a newer iMac 24" bought in 11/2007. I have the mini-dvi to vga converter and when I connect it to a external tv capable of 1024x768, the iMac freezes and does nothing. I disconnect and the screen turns blue and the flickers back on and everything works. I have made the connection then booted up, and I have tried every resolution all the way down to 640x480, same thing it just locks up the screen, but again as soon as I unplug the mini-dvi to vga cable from the iMac it flicks to a blue screen and everything comes back. I have reviewed dmesg nothing, and revieiw /var/log/messages. Is there any troubleshooting I can do. I am old school unix/linux guy just converted my family to Apple and would like to use the display on my tv to watch my iTunes movies.
