27" iMac starts up and stays on white screen and I hear a clicking sound from inside.

I am starting up my iMac and it is frozen on the white screen and I can hear a clicking sound coming from inside?

Hi,
I'm agree with Roger, that could be a HD Failure, but that happens to me once, and the problem was on the Power Supply, so I took it to an Apple Service and it was changed.
At last but not at least, this type of problems could come from the mother board (hope this not to be your case).

As for the folder with a '?', here is some info that might help:

Hopefully you are making regular full backups just in case the hard drive is failing?

MacBook Pro can turn on and off, but does not start up. Stays on white screen with flashing folder icon, does not go to desktop.

MacBook Pro is not starting up. It just stays on a white screen with a flashing folder icon. Have tried restarting while holding the Option key, and the cursor becomes visible and movable, but it does not go to the desktop.

Hello Sonya_Rose,
I found this article when researching the issue you describe here named A flashing question mark appears when you start your Mac found http://support.apple.com/kb/ts1440.
Check the mouse and keyboard
This issue might occur if a mouse or trackpad button is pressed during startup. Make sure the button isn't pressed.
If the issue persists, shut down your Mac with its power button, disconnect any external mouse and keyboard, then turn on your Mac with its power button. If the flashing question mark issue persists, reconnect the keyboard and mouse.
Additional steps
If your Mac still starts to a flashing question mark, follow the steps below. If any step resolves the issue, you don't need to continue to the next one.
Select your Mac OS X startup disk with Startup Manager by restarting and holding the Option key. After your Mac starts up, restart again to verify that the flashing question mark does not appear.
If the issue persists, insert your Mac OS X installation disc. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc.
MacBook Air note: On a MacBook Air, there are two options for starting up from Mac OS X media: Either connect a MacBook Air SuperDrive to the MacBook Air via the USB port and restart the computer, holding down the C key during startup, or use Remote Install Mac OS X to startup from a system software DVD that's located on a partner computer. Once started up from Mac OS X media, skip to step 3.
Restart the computer, then hold the C key during startup.
From the Utilities menu, choose Disk Utility. Don't click Continue.
Select your Mac OS X disk (named "Macintosh HD" by default) in the left side of the Disk Utility window.
Click the First Aid tab.
Click Repair Disk to verify and repair any issues with your Mac OS X startup disk.
After repairing the disk, try to start up normally.
Important: If Disk Utility finds issues it cannot repair, you may need to back up as much of your data as possible (or use Time Machine to back up to a different disk), then erase the disk and reinstall Mac OS X. You should back up important files and data before erasing a drive. Erasing deletes everything on the hard disk (including things on your desktop). Also, you can install Mac OS X onto an external disk, start from the external disk, and use Migration Assistant to transfer items from your usual internal Mac OS X startup disk to the external disk, then erase the internal disk and reinstall Mac OS X.
If the issue persists, and Disk Utility didn't find any irreparable issues, quit Disk Utility, quit the Installer, select your disk when prompted, and restart.
If the issue continues, reset PRAM. Note: After resetting PRAM, if the computer starts up normally, reselect the startup disk in the Startup Disk preferences.
If none of these steps resolve the issue, start up from the Mac OS X Installation disc and reinstall Mac OS X.

Sterling

Macbook start-up but stays on white screen and then clicking noice

I was working on my macbook and suddenly it just became incredibly slow and then it was non-responsive. So I shut it off, and when I turned it back on, it was just a white screen, with the clicking noice in the bottom right corner and then a question mark symbol came up in the middle of the screen and now I can't access any of my important files that I need, Someone help please!!

If you have another computer and a FireWire cable you can try booting this computer into Target Disk Mode by holding the T key at bootup, and then attach the computer to another one via the FireWire cable. This should allow the second computer to see your computer's drive as an external disk.
Alternatively you can try booting up off the Leopard DVD and see if you can access the drive from the Disk Utility software on the DVD. This will be available in the "Utilities" menu after you select your language. From here you can try running a drive repair and hope you can at least get it to be readable.
Unfortunately beyond this, and without any other drive utility software, there's not much you can do without taking it to a technician who can hopefully remove the drive and read data off of it with special hardware. When drives go bad they tend to just stop working altogether.

Plz help. MacBook Pro doesn't want to start up. Stays on white screen starting up!

Ok, so my MacBook Pro is not starting up properly. When I shut it down and turn it back on my Mac just froze on the white screen when starting it up. All I have now is a start up blank screen with the apple and the small spinning wheel below it. Just like starting you MacBook normally but instead it just stays there with the wheel spinning for minutes!!! Nothing come up. Not my sign in screen but the white screen. Pls help!!!

My screen goes to black when i render and a hear a click from my g5

am posting here because problem occurs when using FCP.
g5 problems again, i fear.
curious if anyone else has had this problem...
when i start to render, my screen goes to black and i hear a clicking sound from my g5. if i hit a key on the keyboard, the screen comes back, the render starts up again, and then the screen goes to black again...another click.
ran hardware test...it failed the logic board test...but it failed the logic board test a month ago and when i took it to apple; they said it was bad ram. i replaced the ram and it seemed to be ok until now.
so i repaired permissions using Onyx and then the machine wouldn't restart. pulled all non-apple ram.
reset pmu, finally pulled plug and waited half an hour. tried to re-boot, power light on g5 came on and then went off. wouldn't come back on again.
pulled plug again, called apple.
while waiting for apple to answer...40 minutes...put plug back in and tried to pwr up. it finally restarted, but the same rendering issue.
apple said sounds like logic board problems and is sending someone out early next week...thank god for applecare.
so.....anyone else every have this issue?
thanks
carl

I've dealt with several G5 issues, never heard of this one. Cannot imagine what the logic board could have to do with this since there's nothing particularly unusual about rendering, nothing that is different from anything else the CPU is asked to do.
Please return and close the thread if o get it resolved with Apple's hlep.

Strange problem and clicking sound from speakers!

I have problem with sound but this is strange one and i can't find solution anywhere... I am pretty good with computers and i usualy find solutions on internet when i have problem but this is something i can't solve by myself... My laptop is HP 355 G2 and i have Windows 10 installed on it but the same problem was on Windows 8.1 too... So after clean installation of Win10 the sound was good and worked normaly for 2-3 days and now i only hear a clicking sound from speakers when audio is playing but the strange thing is that when i pick up laptop from the table the sound start to work for few seconds and then the clicking sound comes back again, so i suspect that this has something to do with accelerometer which is built in laptop for hard disc parking in case of drop or something like that... I tryed to uninstal/disable driver for accelerometer but windows install it again emidiatly after reboot, i tryed clean install few times and problem apears again and again... I just don't know anymore what to try to do in order to solve this so if anyone know anything about this please help... And i forgot to say that headphone jack work normaly and when i plug the headphones or external speakers in headphones jack the sound works but the clicking sound still comes out from built in speakers... Thanks in advance and sorry for my English, it is not my native language and there is no support forums on my native language witch is Serbian...

So i tried few more things like disable/enable sound card, driver reinstalation, bitrate changing and everything elese i could find here on forums or on the net (pretty much same stuff like here could be find on internet) and strange thing is that no one have same or similar problem like me... i just don't know anymore what to do...

Imac wont boot - i get a white screen with apple logo, and it loads to about 10%, then screen goes black

imac wont boot - i get a white screen with apple logo, and it loads to about 10%, then screen goes black

Hey there mtriest,
It sounds like you are unable to boot the iMac successfully as it keeps shutting down when you try to boot. I suggest the troubleshooting from the following article named:
Mac OS X: Gray screen appears during startup
http://support.apple.com/kb/ts2570
Disconnect, test peripheral devices and network cables
Note: "Peripheral devices" refers to external devices other than what came with your Mac, such as hard drives, printers, or hubs that you connect via a USB or FireWire cable.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Disconnect all peripheral devices such as external hard drives or printers (leave only the display, a keyboard, and mouse connected).
Disconnect any Ethernet cables.
Start up your Mac.
If you can start up this way, one or more of your peripheral devices (or installed software related to the device) is probably causing the gray screen issue. Connect one device, then restart your Mac to test for the issue. Repeat the process until you locate the device at issue. Make sure the device is powered if it needs to be to operate correctly. Check with the manufacturer of the device for support or possible software driver or firmware updates that may be available for the device. Try a different cable with the device if possible (such as a different USB or FireWire cable).
Note: If you have multiple peripheral devices and the issue only occurs when they are all connected, but not when each device is the only peripheral connected, see the Additional Information section below.
If you are using a desktop Mac with a third-party keyboard and/or mouse device, and the issue still occurs, try starting up with an Apple keyboard and mouse connected instead. Try starting with no keyboard and mouse connected, then connect them after start up. Also, try a different USB port on your Mac.
If the gray screen issue persists with no devices connected, go to the next section (with the peripherals still disconnected).
Perform a Safe BootSimply performing a Safe Boot may resolve this issue.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Start your Mac, then immediately hold the Shift key. This performs a Safe Boot. Advanced tip: If you want to see the status of a Safe Boot as it progresses, you can hold Shift-Command-V during start up (instead of just Shift).
Note: A Safe Boot takes longer than a typical start up because it includes a disk check and other operations.
If your Mac starts up as expected, immediately try restarting.
If the Safe Boot does not work, or the restart after a successful Safe Boot does not work, go to the next section.
There is additional information in the article with further troubleshooting if needed.
Thank you for using Apple Support Communities.
Cheers,
Sterling

Try holding alt when booting to select your hard drive to boot into, if that fails, do it again but select the "recovery" partition (If you have Lion or Mountain Lion)

Hi daveormond,
I'm sorry to hear you are having these issues with your iMac. If you continue to have issues with your Mac shutting down part way through the boot up process, you may find the troubleshooting steps outlined in the following articles helpful (given your description, it sounds like it could be either issue, or a combination of both):
Mac OS X: Gray screen appears during startup - Apple Support
OS X: When your computer spontaneously restarts or displays "Your computer restarted because of a problem." - Apple Support

My Macbook starts up, goes to the white screen with the gray apple, the little loading sign loads, and color wheel appears, and DOES NOT STOP PEIROD!

My Macbook starts up, goes to the white screen with the gray apple, the little loading sign loads, and color wheel appears, and DOES NOT STOP PEIROD!
Even when I restart, shut it down; or when it runs down to no battery, when I plug in the power cord for a while, it loads up to the same stinking screen!
PLEASE HELP ME!

Restart the computer and immediately hold the option key down.
If the computer boots and you see two hard drive icons, use the arrow key to select the Recovery drive, and press Return.
You will get to a screen that looks like the image here:
http://www.apple.com/osx/recovery/
Select the fourth item and press Return.
In Disk Utility, select the hard drive in the left column, then First Aid, then click on Repair Disk.
When that is done, quit DU and restart the computer.

IMac will not get past chime & white screen

iMac will not get past chime & white screen. I have tried all the start up key combinations I can think of (d or c etc) with a start up disc, but no joy. The disc drives seems ok - you can hear it working & it will eject OK.
Any other start up ideas, please?

Have you tried a safe boot? If not, hears how (it's straight from Mac Help):
To start up into Safe Mode (to "Safe Boot"), do this:
Be sure the computer is shut down.
Press the power button.
Immediately after you hear the startup tone, press and hold the Shift key.
Tip: The Shift key should be held as soon as possible after the startup tone but not before.
Release the Shift key when you see the gray Apple and progress indicator (looks like a spinning gear).
During the startup in Mac OS X 10.2 through 10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
During the startup in Mac OS X 10.4 or later, you will see "Safe Boot" on the login window, which appears even if you normally log in automatically.
To leave Safe Mode in any version of Mac OS X, restart the computer normally, without holding any keys during startup.

Hello all,
I have a 14.88G iPod Nano that I currently use as my primary watch. A week or so ago I started to experience a blank white screen when I press the "sleep/wake" button instead of the watch face (I have it set to wake from sleep to display the clock). When I hard reset it, it will come back fine and the screen will respond and work as normal, as soon as I manually put it to sleep by pressing the "sleep/wake" button and then try to wake it the same thing happens and I have a blank white screen that doesn't respond to touch gestures or anything.
What I have tried so far to no avail:
Numerous hard restarts (holding the "sleep/wake" button with the volume - button).
Tried this: iPod nano (6th generation): Hardware troubleshooting
Changed the watch face to display.
Recharged the device overnight (without full discharge).
Since none of this works I'm out of ideas. Eventhough I have a 6G Nano it should no longer be under warranty since I was sent it as a replacement for a different (older) product.
Any ideas? Is this a known problem? Thanks in advance for any insight any of you could provide. Also, what time is it??
Regards,

Hey,
I have the exact same problem as you have described. I also used my ipod as a watch but starting from today, whenever I unlock it the screen turns white until a reset is done. Even a factory reset through itunes didn't fix it.
Have you found any solution?
Bah, this is annoying.
