I would reinstall:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

Imac shut off and the fan is really loud...

I have an iMac 27" i7, 16 gb ram. The screen randomly shut off and the fan became really loud. Tried turning it off and back on, but still did the same thing. Tried resetting the PRAM, heard the chimes, but then did the same thing. Is it overheated?

Check it. Install an app like iStat Pro to check the temperature, and post it here. There are different temperatures (CPU, hard drive, graphic...). If you want, just take a screenshot of the widget (holding Command, Shift and 4 keys, and selecting the widget) and upload it here, pressing the photo icon at the top of the reply box.
Apart, you should run an Apple Hardware Test extended test, to check if there's any problem with the iMac > http://support.apple.com/kb/ht1509 If, after running it, it shows an error, copy it here, because the Mac has got a hardware issue

I have a Macbook Pro that I have just renewed and transferred over my old hard drive (also from a Macbook Pro). Now when I turn on the computer and ITunes opens I get error (-50) and then error 5002 when I try to sign in to ITunes Store - Help!

My dealer has tried and failed (twice) to correct this and I have tried deleting the two items in the Itunes folder but no luck!

were you able to get help on this? I need help on error 5002 as well. thank you

My computer has been freezing and then emitting a consistent beeping until I shut off the power. It has been getting really hot and the fan gets really loud. This has been going on for months. What's going on?

I just had my macbook pro checked out and all of it's systems restarted to solve its beeping and freezing problem. However, it is still shutting itself down when I close the lid and becoming very hot. When I open the lid again the screen is black and I have to continually hold down the power button in order to turn it back on. Does anyone know why this is happening?

The fan gets really loud sometimes

I just bought my Mac a couple weeks ago, not more than a month ago, and I haven't really downloaded a lot onto my computer. But sometimes the fan comes on really loudly, like it's having a hard time cooling the computer. Granted this happens usually when I'm on a site or using a program that is graphic intensive, but it only started doing this sometime this week. Could there be something wrong with the computer?

Your MacBook is behaving as it should. The fan will come on when the CPU is working overtime.
You can run Activity Monitor in the background and see what processes are consuming CPU cycles when the fans come on.
It is Abode Flash more often than not on a website that gets the CPU working hard and the fans going.

My macbook pro is overheating and the fan is really loud. How can I fix this?

My mackbook is overheating and really loud

Try an SMC reset.

If that does not solve the problem, what temperatures are you experiencing in your MBP and what applications are you using?
Ciao.

HT4993 my buttons dont work and music wont play out loud

Music/ videos only plays if i have headphones in have reset phone turned on and off and also restored phone nothing has worked. Has anyone else had this problem and if so what did you do?

You may have busted the speakers. This tends to happen when people drop their phone a lot or you might just have a flawed iPhone. Consult with your cellular carrier or apple store, if you still have a warrenty, you may be able to get a new iPhone.

My cousin tried to restore his Iphone without a back up and now when he turn on the phone its stuck in the apple logo like it its all deleted need help on what to do !!

tried everything used itunes but it doesnt appear in the device list so i cannot do much what else can i try?

just relax and try this http://support.apple.com/kb/HT1808

I have a new Macbook Air and for the last few days the fan had run continuously, this is the first time it has ever run, and now it won't stop, the fan starts up as soon as I turn it on. The computer is not hot.Any ideas on how I can fix this please ?

I have a new Macbook Air, 6 months old, and for the last few days the fan had run continuously, this is the first time it has ever run, and now it won't stop, the fan starts up as soon as I turn it on and the computer seems to running more slowy.The computer is not hot but I am worried it may burn out,.Any ideas on how I can fix this please ?

Hello dwb,
Here is the screen shot, just the top half, there are another 10 pages, but I guess this should enough for you to have an idea of waht is going on, bit small I am afraid. No, I don't have any apps setup to run when I open my computer, the kernel, varies between 290 and 305 per cent ish.
Would that PRAM thing help ? I think it may be the computer itself, well something inside, as this the first time that the fan has ever started running since I have this computer, even when I have 3 or 4 apps running.
Thank you again for your advice,
Regard,
Beauty of Bath

I just replaced my hard drive on my imac and now when i turn the computer on the fan is running and slowly gets louder and louder. how do i turn it off?

thanks.

If your machine was made after 2009 you probably installed th wrong HD. Beginning in 2009 Apple began using HD's that had an integrated fan sensor. If you did not use one of these drives then that is the problem. You should contact OWC (www.macsales.com) or visit your local AASP and they will help you select the correct HD to use.

I have created PDF from hardcopy by using my scanner. After I run OCR option for my PDF by using Acrobat Pro 9. But "Text-to-speech" functionality of the PDF says that an error message comes up that says the page is empty when I turns on the read out loud

I have created PDF from hardcopy by using my scanner. After I run OCR option for my PDF by using Acrobat Pro 9. But "Text-to-speech" functionality of the PDF says that an error message comes up that says the page is empty when I turns on the read out loud option in Acrobat. Kindly help me to sortout this problems?

So I tried generating the same PDFs on two other computers that have Acrobat 9 Pro. Results were reproduced. The verdict is:
- complex PDF files (that is, containing cross-references, tables of contents, and bookmarks) generated by Acrobat 9.x Pro are roughly 2-5x larger than the identical file generated with Acrobat 8.x Pro.
- different PDF conversion settings make a negligable difference (less than 10% rather than 70-80%).
- using the "Reduce File Size" or "Optimize PDF" option cuts the file size roughly in half, almost always resulting in a "image downsampling mask" warning message, which requires acknowledgement (that is a problem for batch processing or automation).
- adding an Acrobat watermark to the file cuts the file size roughly in half.
- just using Save As to another filename has no effect on file size.
- generating the PDF in Acrobat 9 with links but no PDF bookmarks still results in the inflated file size.
- generating the PDF in Acrobat 9 without any links or bookmarks results in approximately the same file size as the Acrobat 8 PDF with full links and bookmarks.
It appears that Acrobat 9's manner of adding links is what's bloating the files, and in my case it's probably not related to images or image resolution/print quality. It's a shame, because Acrobat 9 seems to have made some improvements to the Review Tracker interface, and a few other bells and whistles which I haven't really gotten around to exporing yet. But unless I find a way to keep my links and the PDF file sizes comparable to what I was getting with Acrobat 8 Pro, it looks like I'm going to stay with Acrobat 8.

Does anybody have problems with the Macbook Pro Retina 15' fans being really loud even when playing flash games like candy crush or tetris?

Hey guys,
So after a few months of using the MBP 15' Retina, I've discovered that the fans are incredibly loud even when playing flash games like candy crush or tetris.. are any of you guys having the same problem? Like all of a sudden from be quiet to unbelievably loud just as the games load. So yeah, hopefully someone has the same problem as I am having.
What I was thinking was that the MBP Retina 15' is such a beefed up laptop, it shouldn't require that much CPU to run flash games that are not even THAT graphically intensive to which making the fans that loud..
Thanks!

Believe it or not, Flash REALLY isn't the issue.
It's hardware makers making devices with less processor performance and requiring software makers to fit into a certain requirements of such. Namely iPhone, iPods and iPads.
Flash is designed to give a lot of features and work across many operating systems, browsers and platforms as a write once solution.
Flash has a certain level of processor performance requirement, which hardware makers like Apple want to build less powerful machines using less expensive processors.
Apple has removed Coverflow 3D effects from iTunes and discontinued the 17" MacBook Pro, leaving only the 15" as having a more powerful 3D capable graphics capability.
So Apple is obviously on a anti-heat/performance quest as they further thin up their hardware, trying to kill Flash by punishing Mac users who want to run it.
Flash runs without a fan sound on my older Mac with dedicated GPU and older OS X verison, no sweat.
Head to your System Preferences > Energy Saver and if you have it, uncheck Automatic Graphics switching, this will use the dedicated GPU and shorted battery life, but if your on power should reduce the heat and fan noise.
Another option is to use SMC fan control and set the fan default speed slightly faster, this will keep the machine slightly cooler and not trigger the higher fan speed as often.
If your running 10.8, you will need to System Preferences > Security > downloads to "Anywhere"
SMC FanControl is over at MacUpdate.com.

Need help , when we turn on the mac i can hear the fan and there is a picture of the world flashing for about a minute or 2 on start up . But the fan I can hear non stop ?

A flashing question mark or globe appears when you start your Mac

Computer is unresponsive and fans are really loud.

Last night I walked into my room to hear my G5's fans blaring loud. I tried to move my mouse and the entire screen was frozen. I didn't know what else to do but to hold the power button in to force shut it down. I let it sit for a few minutes and then powered it back up. It made it all the way to my desktop but would not load my icons and the fans started blaring again. So I forced it shutdown again. After powering it back up 2nd time it won't go pass the grey apple screen. The fans are blaring loud again.
What is causing this and how can I correct it. I am able to get online via my Macbook Pro but I really need to get to the bottom of why desktop is acting crazy!!!
Thanks!!!

No.
That is why I always advise,
CLONE and run Disk Warrior on clone, then test that out.
And in the past and for PowerPC, Applejack.
If it is with cache files, those are of course temp files, and which SD doesn't copy, some of which now 10.6.x is better at clearing during a SAFE BOOT but for which people use to use AppleJack (and Maybe Leopard Cache Cleaner) and since we are talking PMG5 10.4/10.5 PPC.
To check all the files, TechTool Pro 5.x or Drive Genius 3 (never used DG, never needed to).
Have multiple backups.
All of these system and disk repair and maintenance? mostly so you can mount and backup any files you need to, and then proceed to restore from good backups.
Usually, people are lucky and they can continue to work. Disk Warrior used regularly and for preventative maintenance (rebuild but also scan files and folders).
HFS+ is not reporting errors (they can be just weak sector, more retries on read) and even ECC is not perfect either at stopping memory errors.

Imac G5 will not boot up. there is power but the screen is black. About 30 sec after turning it on, the fan comes on loudly.

I have an old imac G5 (non Intel) The screen went blank but the fan turns very loudly. I cannot reboot the computer. whenever I start it I get power and black screen and the fan comes on loudly after about 30 secs. I have tried rebooting pressing varius keys, but no luck. I once got the flashing question mark, but I can't get that either. I'd like to reboot from the disc, but I cannot insert a disc. Any help out there??

If zapping the PRAM does not get it working, it's time for a new iMac. Repairs will not be worth the cost. Put it towards a new iMac.
I've been there, done that. Had my burial last summer.
