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.
View 3 RepliesI'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?

over the past few weeks my blackbook has been shutting down more and more frequently from what I can only believe is overheating. I just checked my computer upon startup with SMC fan control - it starts up at about 70 C and at about 3500 RPM. Yet, after a few minutes, the fan immediately drops down to 1100 RPM or and fluctuates between 800-1400. I try to force the fans to spin with SMC Fan control, but nothing happens. I've looked all over the web and I can't find anything definitive. I know that macbooks tend to overheat. What can I do?
View 3 Replies View RelatedI'v just noticed, after installing iStat menus, two different CPU usage measurement graphs. Core 2 duo, so apparently one for each core or chipset, whatever . But the weird thing is, that sometimes, while watching movies, burning dvd etc. (sample "high usage" situation), when the CPU temp. goes around 60 celc. and fan spins at 6200 rpm, one of the "core graphs" shows nothing, like the core is shutting down (screen attached). It's annoying, because the whole system slows down, I can't do anything, and after like 5 mins it gets back to normal (after closing for example the movie). Any solution for this or should I just get used to it?

View 5 Replies View RelatedI've googled to see if I can find a solution to this but not had any luck - wonder if you could help. My Mac Mini is 1.5Ghz PowerPc G4, 512Mb RAM, running Mac OS X Version 10.5.8. I bought it second hand a couple of years ago and in the past while it's really been playing up a bit. It first started overheating and shutting down when I was doing really resource intensive stuff - for example, opening a large amount of RAW image files. However, it's now started taking to shutting down when I'm doing normal browsing, using Spotify etc The machine also tends to hang a lot, and I can't really stream videos very well either. The vents at the back of the Mac definitely aren't blocked and there's plenty of space around the machine to let the air circulate.
View 6 Replies View RelatedMy Macbook is 1.5 years old (13in, white, 2 GHz). About two weeks ago, it would randomly shut off. It would restart fine, but shut off sooner. Sometimes, it wouldn't even restart. Now, it's at the point where when I power it on, it rarely restarts past the white apple start-up screen.
My thought is that it is overheating. Are there any more ideas? What can I do to save my macbook?
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.

View 1 Replies View RelatedMy Macbook's been overheating and shutting itself down the past two days, usually when on YouTube. Having installed the Fan Control system preference, I can see the fans aren't running at all. My first thought is that they might be broken, but this happened for a little while last year, too, and the fans started working again after a while. Also, it's been miserably hot in my area the past week, and I wonder if that's contributed to it, too (even though the laptop's in an air-conditioned room). Anyway, should I wait and see if the fans begin working again, take it to a repair shop (warranty's expired, so I'm not keen on that), or maybe buy a cooler pad?

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.

I checked [URL] and there seems to be issues with power on some models, but his serial number just misses the infected batch.
I looked into my issue a little but recently my IMac G5 started randomly shutting down when left unused for a bit but that seems to have stopped as far as I have noted. Now occasionally when it goes into sleep mode it will freeze on the black screen and the fan will go crazy. I plan on buying a MBP, if the update ever comes out, and then ill just completely wipe the IMac and give it to my parents, who still use the original I mac, G3 or something. I read a certain series of I Macs were having motherboard problems, W950 or something, but mine wasn't that serial code.
View 2 Replies View RelatedI have a G5 2.7ghz powermac. Recently it began switching itself off at start up. If it did boot up - it would only last for a few minutes that it would freeze.
I clean out the dust from the inside and even took the cpu cover off - none of it has made any difference. I have also replaced the lithium battery. Has anybody else experience this?
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.
I just bought a brand new imac running 10.5.7 3.06 Intel Core 2 Duo 4 GB 1067 MHz DDR3 i downloaded Handbreak to rip some of my dvd's and put them on my external hard drive as soon as i open handbreak and start ripping a dvd, the fans in my computer start whirring away, pretty loudly i downloaded the istatnano widget to check my fan rpm's and temps
While Running Handbreak:
Fans:
CPU Drive - 3605 rpm
Hard Drive - 2408 rpm
Optical Drive - 2195 rpm
Temps:
HD - 57
CPU A -46
CPU A - 80
GPU - 53
GPU Diode - 48
GPU Heatsink - 47
Ambient - 27
is this ok? is there something wrong? the fans are just so loud
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?
View 6 Replies View RelatedI had my iBook G4 a few years ago, and since I was about eleven when I had it, I'm not sure I always took the best care of it, but it's always worked pretty much fine up until about a week ago. It's started shutting down randomly. It also sometimes randomly goes to sleep in the middle of things. In particular, it doesn't seem to like starting up, or the internet, especially if I'm on youtube. I've tried a PMU reset, as it worked once before when my laptop wouldn't start up, but it hasn't worked properly. It's worked from anywhere from a minute from the time I start up again, to about a day or two at most, but it always seems to shut down again.
I really don't know what else to do with it... and I don't understand how computers work at all.
I recently got my 3.2ghz mid 2010 21.5' imac. I noticed that its been getting really really hot on the top on the top left and right corners of the computer. Usually i am watching tv series (.avi) files on it using quicktime and vlc and i checked the temps reaching these as follows
HD 54
CPU A 50
GPU diode 71
GPU heat sink 68
memory 58
optical 51
and the fans are at
CPU fan 1470 rpm
HD 1099
optical 1000
are these temps okay? or is htemachine over heating for the activities i am doing, usually i amjust msning, and watching tv series.
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?
View 4 Replies View RelatedMy 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.
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?
View 22 Replies View Relatedif anyone with the latest 15" DL DVD Al Powerbook has had it shut down unexpectedly? I'll just be doing something (checking email, surfing web etc) and it'll just turn off no warning, no "shutting down" message, no low battery warning, nada. just dies. I'll be able to reboot using the power button straight away (even using battery, so it's not a low battery charge problem) and it works normally again, but has to do the full reboot sequence. It's a bit spooky really. i'll be happily going along and suddenly nothing. Problem is, it'll only happen after i've had it running for a few days (i just shut the lid after i'm done with it) so it would be very hard to prove to Apple. Anyone else has had this happen?
View 3 Replies View RelatedMy iBook (about 3 years old) all the sudden started continuously restarting. The screen would dim and a black window would appear saying that the computer needs to be restarted with a picture of the power button symbol behind it. I have done that and now the same thing keeps happening every time my computer turns back on. It has happened 4 times in the last 20 minutes. One time as soon as it restarted, it shut itself off as soon as the desktop appeared. Does anyone know what this means?

View 6 Replies View RelatedI 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.
