Cpu fan goes crazy and wont start up

maybe its a cron or trashing problem done in the terminal. how can i boot or restart my mac?

See if any of these key combos work...
Does it boot into Open Firmware with CMDOption+of ?

reset-nvram (press Enter)

Have you done a PRAM reset...

Boot off your Install Disk while holding down the d key, (not c key), then run the extended Apple Hardware Test.
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
The usual reason why updates fail or mess things up, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions.
Some people get away without Repairing Permissions for years, some for only days.
If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!
If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates.
May even need to do an Archive and Install if you have room on the HD...
http://docs.info.apple.com/article.html?artnum=107120
I only use Software Update to see what is needed, then get them for real via...
http://www.apple.com/support/downloads/
That way I can wait a week or so, check the forums for potential problems, and get Permissions & such in order before installing.

CPU Fan going crazy (over 3500 rpm) all the time iMac 24"

Hello,
I have had an iMac 24" since Aug 2009. I had no problem until up a month ago (coincidentally after I installed Mountain Lion).
The CPU fan becomes very noisy, reaching 3500 rpm and more. I checked and the CPU temperature is around 90C when this happens.
It happens invariably after very little usage of the computer. Sometimes it's when I'm watching a DVD, sometimes is when I'm copying files from a USB hard drive, sometimes I'm just surfing the web.
I have brought my computer to the Apple Store twice already. The first time they told me I should reinstall the OS from scratch, after erasing the disk (which I did), the second time they told me they had found the problem and fixed it, for free! but it presented itself as soon as I turned it on back home.
The CPU temperature is around 80C right now, and I only have safari opened and I haven't reinstalled any program since I reinstalled the OS.
Do you have any idea of what it could be? Could it be that the sensor is detecting a wrong temperature? In this case, could I set the fan speed manually? I know it is not advisable, but the people from the apple store are not helping
Thanks for any help you could give me,
Biagio

Please start by doing a SMC Reset,
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
If necessary repeat process.

1.8 Power PC G5 Fan goes crazy and stays that way!

So this has been happening for about 2 weeks now. I've tried the suggested "Pull the power cord out and let the SMU restart" thing and that has no effect on it. I would rather not take it in to an Apple Store. Any suggestions? It will usually start up just fine and then give the occasional rev about 10 minutes after boot, then 15 minutes after boot its going all out loud fan noise. If I let it go, it will die down again...but then stop. My temperatures are fine.

Hi Cody,
Might be time to replace the PRAM Battery, 4 years is close to their lifespan...
See which one your G5 has...

Mac Os 10.6.6 update start the fans goes crazy

Hi to all
Some months ago (almost a year from now) my mac start to become hot after only a few minutes it started up and the fan goes crazy but I never realize why. I made some search on the internet but the only answer I found was using some software to reduce fan speed. It didn't work. I run the Hardware test but nothing strange. I also took my macbook to an apple certified repair center but they told me that nothing was wrong. I also ask to another repair center but same thing. So I left my macbook as it was with this super fan noise all the time. A quite disturbing thing but there was no solution and for what I'm doing my machine is ok so why change it? (It was the only solution they gave me)
Last day my hd broke down so I had to replace it. I took my macbook pro a1211 model to an apple repair center they change the hd with a new one.
So I reinstall everything for the beginning. I took my snow leopard dvd formatted the new hd, installed the os, iWork 2008, iLife 2008, Mamp, CSS Edit, Espresso, Pixelmator and few other application such as Firefox, Camino, Etc...
I use the macbook with mac os 10.6, because I had to finish some work, and with my big surprise for two days the machine was super silent no fans, no hot body ..... nothing. I never reboot it and still no fans and hot body wow.
Today I wanted to install the developer kit with ios 4.2 and so I had to update the Mac os x to version 10.6.6 as soon as I made the update after the reboot the fans start again to go like crazy and after 15 minutes of work the macbook body become very hot.
The question is why?
Anyone can help me?
Thanks in advance
Gianfranco

HI R C-R.
The apps i've installed are just a few. Espresso, CSS Edit, MAMP, TextWrangler,Firefox, Camino, Chrome, Opera,BetterZip, Stuffit Expander, Pixelmator, 1Password, Dropbox, Xslimmer, VLC, CyberDuck, littlesnitch, iworks, iLife, wacom tablet driver.
Nothing more. All the software is updated.
Here the data but as you can see nothing strange but fans are on at the maximum speed!

My macbook pro 2006 fan goes high and then makes a fast beep and shuts down it been happening since i updated

my macbook pro 2006 fan goes high and then makes a fast beep and shuts down it been happening since i updated it should i update to lion?

No, this problem should be solved.
The MBP shuts down when too hot, to protect itself. First see if it is a process running astray: start Activity Monitor (in Applications/Utilities) choose <all processes> and click the %CPU column: are there processes that are using more than 50% cpu power? If yes click it and quit it, and tell us which one.

Fan going crazy when booting

When I boot up iMac, the fan goes crazy. After a moment it stops and is quiet again. I unplugged my power and plugged it in again but that does't work. I tried to start AHT by holding D when booting, but that didn't work. I didn't get any discs when I bought my Mac so I can't run AHT using the disc. How can this be fixed?
I also have Windows 7 installed but I don't know if this is relevant. The fan goes mental everytime i boot up. It doesn't matter whether I do that with Windows or OSX.

My ipod is displying apple logo and wont start up, hard reset leaves it the same, disc mode works but iTunes doesnt "see" it even if the computer does.

"My ipod is displaying apple logo and wont start up, hard reset leaves it the same, disc mode works but iTunes doesn't "see" it even if the computer does."
It worked two days ago fine, for two years, until I installed this newest iTunes update, then for one day it kept on freezing and going to apple logo screen mode, then today it only goes to that screen and wont start up at all.
I've tried the hold down two buttons hard reset, that doesn't help. I've tried disc mode... but iTunes doesn't "see" it even if the computer does.
This is a pristine ipod, never exposed to adverse conditions, never dropped, never wet, and it worked perfectly two days ago.
Can I factory reset it somehow? (considering itunes can't "see" it)
[Ipod classic 160gb less than two years old.]

Looks like I might have found the solution on a youtube comment:
R.O:
"Plug into you laptop first, whichever set up you use that has iTunes, i know it won't read it, don't even open iTunes as of yet. Do the typical reboot "Menu +Center button at the same time" and hold it, DONT LET IT GO like we were told, when the apple pops up.. KEEP HOLDING IT it will make a new ding sound I've never heard before. and since its hooked to you laptop already an error message pops up and says apple will need to download something to repair your iPod. I when u see that that when i let reboot buttons go. hit ok on the laptop something downloads for like 20 seconds then the iTunes icon hops around when you open it it has a screen with an iPod classic on it and says "Software version blah blah, iTunes will check for an update on such n such date" AND FINALLY there's a "Restore" button. click that and you will be back to square one with your iPod. Renaming , adding all the music on it, but it will work again, finally. "
I had to do it twice, because my mac froze the first time, but its recognized it now and is downloading the software as we speak...
Now I've clicked the restore button and it's restoring... I'll post again if its a success, otherwise assume failure.

Iphone stuck with apple symbol and wont start up

i updated my iphone and when it finished and went to reboot it just stays stuck on the apple symbol it constantly reboots and will never connect to my laptop i dont know what to do if anyone can help please do

Hi,
Luca224 & Ingo2711. Thanks for bringing this topic. on 29th Nov. I faced the same problem on my iPhone 3GS 32GB Firmware 3.1.2, iPhone stuck with apple symbol and wont start up. I have tried with 10 Seconds Sleep/wake-up button + home button to reset. But didn't work. Did google about an hour with many blogs. Finally I made a call to 3 iPhone care and spent 30 minutes and explained whatever I have done; iPhone customer care asked me to go to nearby iPhone service center in Sydney. BUT BY LUCK CLICKED ON iTUNE AND GOT THE OPTION FOR ONLINE FORUM FOR APPLE iPHONE. Many many thanks to Ingo2711 who has given the solution link and also thanks to Luca224 , who raised the issue. I feel, this is a common problem with iPhones those who using iPhone 3GS 3.1.2...... but try the link http://support.apple.com/kb/HT1808 and thanks to Luca224 & Ingo2711. PLEASE FOLLOW THE INSTRUCTION CAREFULY:
1. Verify you have iTunes 7.5 or later. Apple recommends using the latest version of iTunes.
2. Disconnect the USB cable from the iPhone or iPod touch, but leave the other end of the cable connected to your computer's USB port.
3. Power off the device (Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the the iPhone or iPod touch to turn off. _+(in my case - red slider didn't appear, but i pressed the Sleep/Wake button until the iPhone went off, finally it was just off... i was frustrated... tried 3 times with more patience )+_
4. Press and hold the Home button while reconnecting the USB cable to iPhone. When you reconnect the USB to iPhone, the device should then power on. +_( Do exactly as it says)_+
Note: If you see the message "Charging... Please Wait" or you see the screen pictured below, let the device charge for at least 10 minutes to ensure the battery has some charge and then start with step 2 again. +_(True ... for me it happened 3 times)_+
5. Continue holding the Home button while iPhone starts up. While starting up, you will see the Apple logo. +_( I was nearly frustrated at my 3rd attempet; my thumb was hurting as I was holding the home button for few minutes..... but finally it worked yahooooooooooooooooo...... suddenly changed my decision.... about going to 3/Apple service center)_+
6. When you see "Connect to iTunes" on the screen, you can release the Home button and iTunes will display the recovery mode message:
If you don't see the "Connect to iTunes" screen, then disconnect the USB cable from iPhone and repeat steps 3-6.
Because you must restore iPhone or iPod touch, iTunes will not recover data from the device, but if it was previously synced on the same computer and the same user account, it should restore a backup (if available). See document HT1414, "Updating and Restoring iPhone Software."
If you are still unable to restore the iPhone using this method, check Apple support for further troubleshooting and/or service options.
Note: If you sync both an iPhone and an iPod touch to the same computer, make sure you select the correct backup to restore your settings from (don't select an iPhone backup if you have an iPod touch and don't select an iPod touch backup if you have an iPhone).
**** ( BACKUP FROM YOUR iTUNES : MAC/PC; AS I GOT MY 95% DATA FROM THERE.... GOOD LUCK)******* IF IT WORKS PLEASE POST YOUR EXPERIENCE....*
THANKS

lllaass thank u bro, but none worked for me
i have tried all these methods n above which i mentioned before....
- Powering off and then back on your router.
- iTunes for Windows: iTunes cannot contact the iPhone, iPad, or iPod software update server
- Change the DNS to either Google's or Open DNS servers
Public DNS — Google Developers
OpenDNS IP Addresses
- For one user uninstalling/reinstalling iTunes resolved the problem
- Try on another computer/network
- Wait if it is an Apple problem
in the end i went ot market n paid him 1.94$ and he restored it to 6.1.5... and said apple has closed other ios updation except 6.1.5 ...but still thank u soo much learned some new stuff from u...

Google Maps going crazy and allignment problem

Help - I have got a site - www.elitepolefitness.co.uk which I have uploaded with Fetch (I have my own hosting) the embedded Google map is going crazy and the address is dark grey and left alligned instead of light grey and centered. When I upload the files to Fetch and preview site through there, its perfect. Please help!

Problem solved - I moved the files to different place - onto my Mac HD rather than my external HD. This is a massive pain though, I don't want to store all my websites on my Mac HD. Please try and fix this problem soon.
Could you advise on the next update/new features?
Thanks for your help - much appreciated.
