IMac G5 over heating?

I have been trying to burn a DVD using toast and every time I try my Mac restarts itself. I think it might be over heating. Looking at the temperatures using the iStat Nano widget my CPU regularly reaches 66 degrees but I don't know at which point my Mac restarts as I;m always out of the room. Everything else is working fine. I have burned DVD's before and not had this problem. Any ideas what I should do? Could it be dusty inside?

Hi,
You could check logs in Console to track down the cause of the spontaneous restarts.
Also, it could be related to a power supply issue. There are a couple of Repair Extension Programs for the iMac G5, related to Power Supply Issues, and Video and Power Issues.
Good Luck.

Why is it that I have to install a third party software to control my fan speeds when my iMac gets hot. Should't the system manage this. My iMac is over heating because of this. Is there a way to let me iMac manage the fans?

I've read many posts talking about using a third party software to manage the fans in my iMac. Can the iMac not do this on its own?

You don't have to do anything. The fans will run when the temperature gets hot enough to trigger them.
My new 2012 iMac isn't like my older 2007 iMac in terms of fan noise. I knew when the 2007 fans were running, I could hear the sound of rushing air and under heavy load they were load. Because the new 2012 models are very different in construction I don't hear that typical sound. In fact, until I saw a teardown I wondered if it had fans. The fan sounds more like a hum and I just never associated it with being a fan. Yes, the top of the computer does get hot, I think part of Apple's design is to use the alumnium back as a heat sink.

How do I find out if my Imac is over heated

I wanted to know how to find out if my mac overheats. I think that's what's causing game crashes. If possible I also wanted to find out if my fans work.I haven't heard them come on. Only once.

Hi,
as for temperature and fan readings have a look at iStat Menus http://www.islayer.com/apps/istatmenus/ and (if neccessary) SMC Fan Control http://homepage.mac.com/holtmann/eidac/software/smcfancontrol2/index.html to rev up the fans.
Hope it helps

Over heat!!

I have my new power book 12" for 6 months
every time i work on it (about 1 hour), the whole notebook
gets over heated, the sound of the fans are loud and the process
speed drops and some times the system would halt.
the battery serial isn't in the range of the recycled batteries
anyone know what the problem is?
or does everyone has the same problem?

Those applications, especially if you have the same memory as me (512) will make the processor work for its supper, but should not be causing excess fan operaton or a need for multiple fans. Like you, I live in a warm climate (Bangkok) and none of my computers, apart from my earlier iMac, which had no fan, have suffered from heat problems.
Let me also include D3MON here. Have you (both) checked to see which widgets are working? Sometimes quitting these (or even Dashboard itself) has helped some folks.
If you use the Activity Monitor, are all processes displayed? I just tried top -u and that is not all.
I notice that both of you are using graphics software, and D3MON specifically mentions QuickTime. I occasionally had a problem when using QT with iTunes and video podcasts: the screen sleep would not function. If a restart fixes it for you, how about just logging out?

How can I turn my MacBook Air on after an over-heat-shutdown?

I was using my Mac today and it suddenly froze and the date on the top went funny. I tried pressing buttons on the keyboard and nothing seemed to work. So I pressed and held the power button down and it turned off. Then I tried turning it back on but, it won't. The white status light on the bottom side of the computer becomes bright and then starts blinking with an alarm sound. Im not sure of the reason for that sudden freeze. I think its cuz of over heating, cuz I left it turned on since last evening. (MacBook Air, Intel Core 2 Duo, OSX Lion)

As BobTheFisherman already said, it is impossible to say until you find out just what was damaged. If enough coffee got inside it, it could well be the logic board and every other piece of circuitry inside is fried. Or it could be less damaged and repairable. But you really need someone to open it up, disassemble it and find out just what was shorted out and how extensive the damage is.
I would forewarn you that you may be looking at having to replace the whole machine, in a worst case scenario.

Battery Purging and Over heating Phone!

WHAT?!! I have assumed that my LG Revolution spontaneously purging the entire battery charge at once then over heating and shutting down was a hardware issue! Now I find that it is the result of yet ANOTHER OS SOFTWARE upgrade issue?! OMG are you kidding me?!! I have been PLAGUED with problems since I was forced to upgrade my android OS to 2.3.6 through Verizon! I am ready to make ANY change I have to escape this plague!! I PAY WAY TOO MUCH MONEY for android smart phones and premium service through a so called 'premium' provider to have to put up with economy freakin performance Verizon!!!
I am especially disappointed in Verizon since I took the phone all the way to their coorporate store 5 months ago and all they did was scratch their heads! They tried to sell me a new battery which also immediately commenced to over heat; so of course the next course of action was to try and sell me a NEW PHONE!
I've been sitting here with a DEAD VERIZON phone all day AGAIN trying to rescucitate it!! ****, that **!

Thank you Verizon; you're right. Buying a new phone is the fix! I bought a brand new LG Spectrum at the Verrizon store yesterday and my old LG Revolution immediately began to work perfectly again. That was the fix. Of course....
You think this is messed up? It just gets weirder. Before going to bed last night I took my new LG Spectrum off a 4 hour charge because it was full. It slept all night. When I checked it in the morning it had one missed call and 6 emails; that's it. The battery charge however was completely on EMPTY! OMG!!?? What the....? Yesterday I was rather puzzled by how exceptionally warm/hot it felt while on charge. The charger plug also felt the same. It's on charge right now using the supplied charger but I changed it to a different outlet. It's still very warm/hot. I'm befungled!! I live in a 1/2 million $ condo packed with properly working electronics' so it's certainly not a source problem.
More weirdness: yesterday I was downloading and re-installing programs and updates to reload my new phone. A couple of hours later it went on an all out download splurge all on it's own, one after another it was a stream of unwanted downloads I couldn't stop. I turned off wi-fi, but eventually had to shut down the phone right in the middle of processes..... not a good. (UPDATE: solved this issue. I discovered that all the bloatware pre-installed on the phone further imposes itself by ALSO being set to 'auto update' itself. Oh! cool! and check this out: it won't let you uninstall any of that sh*t! Cool huh? Thanks LG or is it Verizon; I want to be sure to give due credit to whomever is responsible for that *** idea!)
My new not-so smartphone phone, less than 24 hours old, is already fouled.
UPDATE: 5 hours later. No phone call usage today. Emails, texts, a few downloads, and some new phone setup configuring today. Phone is dead after 5 hours of use. Took old phone off 1 hour charge and of course it was as cool as a cucumber, plugged in new phone and it became hot within minutes. I think that the solution is to just go back to using landlines....
Attached below is a photo showing the EKG of the entire life of my NEW phone. 1 day and 7 hours. Hmph? And I am already in the forums. Anyone know what the record is?

I have done absalutely nothing to my 4g apple ipod touch, and it over heats, won't hold a charge, and the front camera will not work. I bought this brand new in december, and i've barely used it. I've tried restarting it and everything, what should i do?

I have done absalutely nothing to my 4g apple ipod touch, and it over heats, won't hold a charge, and the front camera will not work. I bought this brand new in december, and i've barely used it. I've tried restarting it and everything, I honestly think this is out raging because i spend over $200 on this. To have for music and instagram. I use it about an hour a day, but i've only been using it for about 3 months although i've had it since December. Any suggestions that may help me?

Try:
- A reset. Nothing is lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory settings/new iPod
If still problem make an appointment at the Genius Bar of an Apple store.

Over heating on charge and it is no longer showing anything on the screen

My iPhone 5 is over heating on charge and it is no longer showing anything on the screen. I was using it when the screen went white and it hasn't worked since. I have tried to both restart it and to restore it. as the screen doesn't not work it is hard to tell the condition of the phone. However it occasionally makes the lock noise when pushing the lock button and also occasionally vibrates when operating the side switch. I can not leave it plugged in on charge as it gets very hot and it is no longer recognised in iTunes unless i put it in recovery mode.
Has anyone else has this problem or can recommend a solution. I bought it second hard a while ago so it is not under any warranty.
Thank you

Sounds like the battery has become unstable
Take it to an Apple store Genius bar for evaluation Suggest you do not attempt to charge any more
at worse Apple may offer an Out of Warranty exchange device identical to donor
In UK price over the counter is £209

My iPod touch 5th generation had white screened an it won't let me rest it by holding down the home button an the power button for ten seconds I've pulled it in to iTunes an its not being detected what can i do as its starting to over heat?

If you can't get it to shut down or restart when holding down the Home and Sleep/Wake buttons and you can't get it recognized in iTunes to restore it, the iPod may have suffered a hardware failure and will need to go to Apple for service. Someone else here may have additional suggestions, though.
There is no "fifth generation" iPod touch, by the way, just for the sake of clarity; not yet, anyway.

This is a user forum and is not Apple. I would definitely recommend that you stop using your iPhone and take it to be checked.

Exactly what model MacBook Pro do you have?
Many MBP's have two graphic processors (gpu's) and if you are using the dedicated graphics processor, your MBP will heat up a lot more than when the built-in graphics processor is in use. For example, the current non-Retina MBP's have both a built-in Intel HD 4000 graphics processor and a dedicated NVIDIA GeForce GT 650M graphics processor.
You can control which video processor is in use via System Preferences > Energy Saver. If you are running Lion (10.7) there is an option for Automatic Graphics Switching which you should turn off (disable) in order to use only the built-in video processor. In my own experience I have found very few cases where the dedicated gpu gives 'better' performance than the built-in gpu.

HT4061 I got a brand new iPhone 4S on contract last week and since I've had it it's been over heating and it's turned itself off once and every now and then the screen flickers I just wanted to know is this a common thing as I've never had an iPhone befor

My new iPhone 4S that I have had a for about a week keeps over heating a lot and its turned itself off once and I couldn't turn it on for over half an hour,also my screen flickers from time to time and I'm not sure what to do as I not had an iPhone before can anybody help me please I would be very greatful.

No, it's not normal.
Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new).
Frankly though, considering it's new, take it back to Apple.

Laptop over heating then shutting down

Model; Satellite L355-S7812
I've hade this computer two years. It started over heating then shutting down soon after I purchased it. It use to take 4-5 hours before it overheated now its less than an hour. What can be the problem?

Probably the fans. They may need to be replaced. The Qosmio I purchased in 2005 had the same problem. I replaced the fans twice over the 5 years I used it. Fan issues are known problems with certain models, especially those that have high CPU usage. By the way, a Toshiba technician told me never to place the laptop directly on the lap or on a soft service like a bed. The fans can't ventilate properly, especially if they are located on the bottom of the computer. Since I have done that, the fans have worked fine.
