imac intel 10.4 wont start up. i don't get apple logo as the screen just goes white. i can hear click-click-click then a question mark instead of apple logo. if i insert install cd 1 i get apple logo and install instructions with no hardrive logo to install on
Yikes, sounds like the Hard Drive is dying.
Which exact iMac is it?
If you don't know the model, find the Serial# & use it on one of these sites, but don't post the Serial# here...

My ipod nano 6th gen doesn't start. When I plug it, only blink the apple logo on the screen. I try to reset it holding by 8 seconds start button and volume down and doesn't work. My Ipod doesn't have any shock or water damage. How can I do?
Hey rulosrojos,
The article linked below details a number of troubleshooting steps that can help restore functionality to your iPod nano.

IMac starts with sound but remains with Apple logo and the clock running indefinetely
After software upgrade ( from mavericks to new mavericks ) iMac doesn't start anymore. It remains always in the same mode: after the sound of start the Apple logo and the clock that runs indefinitely without the start of the software. Someone knows what to do?
Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use either of the techniques in Steps 1b and 1c to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 10
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 11
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 12
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. -
Hi
I've just reset my iPhone 4s as I was planning to sell it on. After the normal stuff you see on a reset I've been left with a phone that just has the apple logo on the black screen and it appears to be frozen and wont do anything?? any ideas?
I've tried holding down top button and round button which makes it go off but as soon as you push top button again it comes back and again its frozen.
Thanks for any ideas in advance?You need to put your iPhone into recovery mode to restore it: If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support

Try to backup and restore you device in itunes...restoring the device is like removing the iOS software off the device and re-add in a newer software, after you have restore you device, MAKE SURE YOU SET UP YOUR DEVICE LIKE A NEW DEVICE, DONT NOT RESTORE FROM BACKUP!!... give the device a chance to use the newer software and see if the issue still persisting, if the issue still on going then its would be a hardware issue.
Call Apple Care and see if your device is still under warranty to get it replace -
On start up of my new iMac it locks on the grey screen with the apple logo and the progress wheel spins. Boot up in safe and this is where it stopped at "BootCacheControl: Unable to open /var/db/bootcache.playlist: 2 no such file or directory. "
Reinstalling MacOS does NOT fix the problem for me. I'm still searching a solution !

My iMac turns on the start up chime sounds, you see the apple icon on the screen and then it just shuts off. Any ideas?
Do these two resets:
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
The 5 second timing is important to a successful reset.
PRAM RESET
Zap the PRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys. -
My iMac 27" is 2 years old. The screen just start to sleep every 2-3 minutes and then one has to reboot it. I bought the unit from Incredible Connections in South Africa. They sent it to the South African distributors Core. They report LCD screen defect and charged me R7500-00 to replace the screen and sent it back after 4 weeks.
It does not go to sleep anymore; but when switch on; there appears a flickering band of lines on the screen which last for about 20 seconds before the machines starts to work normally.
It seems there is still a screen problem!
We had to send it back again.
The other problem is that you just get no communication out of the Core workshop and you cannot communicate with the technician.
They had still not provide a technical report in spite of repeated discussion with the manager of Incredible Connections.Sounds like the graphics card might be the problem. Run the Hardware Test in extended mode. If you get an error it can be trusted, but getting a negative may not be all that meaningful. Bring it back to them and let them check out the machine again.

When I started my iMac today, it started beeping like an alarm horn. I shut it down, and held the startup button a little longer to get it to start. Shortly after starting up, a dark 'film' slowly comes down over the screen and I get a message saying I have to shut down the computer. I've tried to start from the disk, and before I can even run a repair off utilities, it happens again. What's up? Am I screwed? HELP!!
What you are seeing is a kernel panic, often but not always connected with a hardware or peripheral issue, so, unplug everything except mouse and keyboard, reboot and hold the shift key as soon as your hear the chime, continue holding it until you see the Apple Icon and spinning progress indicator, then post back.
It will take noticeably longer than normal to start. -

My iMac is less than one year old. Without warning, the screen suddenly goes black. It used to happen ocasionally, but now it happens all the time. Numerous people have posted about this issue. Why hasn't Apple solved the issue. For what I paid my computer, I expected more from the product than I have gotten. I was a PC person for years and most of my associates told me that I needed to get a mac...I am starting to regret having taken their advice.
Sorry you're having this problem.
A few years ago we had a similar issue on one of our machines, it was an early MacBook. Ended up being a cracked circuit connection on the motherboard. Changes in temperature caused the crack to expand and contract resulting in a shut-down followed by an automatic reboot. Sometimes over-and-over. I understood from AppleCare at the time that those symptoms could have also been any number of things including a intermittent issue with a powersupply.
If you take it back to the Apple Store at some point, I would ask them to have it run some CPU intensive tasks that closely resemble what you are doing when the screen goes black. It took us several try's to find the problem. Calling AppleCare each time to discuss it and troubleshoot before making the trips to the Apple Store really moved things along. In fact, it wasn't until the Apple Store had cracked the case from the inside that things kicked into a higher gear and AppleCare phone support sent out a pre-paid FedX package to send it to a refurbishing facility. Never a problem since and I know the people who have the machine today.
PS Can identify with the trip to the Apple Store, our closest one is in Knoxville, 2hrs from us. -
How do I fix a initializing problem with my macbook pro? I only get to the blank screen with the apple logo and the "processing something" sign... it just doesn't start the system....
Please help
MarceloIf there is no loading bar, it's usually a problem with a third party kext file in OS X itself.
You can press the power button down to force a hardware shutdown, then reboot holding the shift key down on a wired or built in keyboard, this will disable them and you go around and update your third party software.
Gray, Blue or White screen at boot, w/spinner/progress bar
Also take this time to backup your users files off the machine if possible.

Ok so I have tried evey combination of restarts. It tries to boot up, the start up bar appears on screen, but the computer just goes completely after the bar is a third of the way across. Is is doomed?
Have you tried booting into the Recovery HD and running Disk Utility to see if anything needs fixing on the HD. Restart holding down Command+r and once it hopefully boots select Disk Utility>Repair Disk. If anything gets fixed click on repair disk again until you get a clean pass. Try restarting as normal from the Apple menu once done.
Do you have backup to restore from if it proves to be the Mac has a hardware fault? -
Hi,
I was wondering if someone can help me. I have a MacBook Pro, it has came up saying I need to free up space on the disk as it full every time it starts up, so I log in and no icons or applications show up on the screen just my background wallpaper, the only thing I can do is the force quit keyboard shortcut but there is nothing to quit, I have tried to start up in safe mode but again there is no icons in the desktop,
I have my disks that came with my laptop I have went into disk utility to repair disk and I still seem to have the same problem .. No icons or apps or anything lol just the cursor I can only shut down the laptop via power but and the press shut down.
Please help I am going out my mind with this thing :(
