Thank you for your support.

You need to take it in for service, it may be a stuck key or component failure.

Intel OS X 10.7 iMac has white screen and three-alarm sound, won't start up

The 3 beeps during start-up are telling you that the RAM is bad.
If you can access the RAM modules, you may try taking them out and putting them back in, perhaps it's only bad contacts.
If that doesn't help, you'll need new RAM module(s).

it really depends on what exactly the problem is. take is to an Apple Store or AASP and have them look at it

You may not have done anything. Parts can go bad on their own.

What do i do if my ipod wont turn on/off, shows a white screen, wont do anything, and wont connect to itunes

what do i do if my ipod touch wont turn on/off, shows a white screen, wont do anything, and will not connect to itunes

Let the battery fully drain. After charging for an hour try a reset
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.
and restore as necessary.

Festus,
I'm getting you have a MacBook rather than an iMac, if so you may want to request to have your post moved to the correct forum. However please read Gray screen appears during startup to begin troubleshooting your problem.
Also when posting please do not type in all caps, it is considered shouting. We can "hear" you fine.

Does anyone know about a white screen upon start up?

My daughter has an older MacBook and we have upgraded software. She tells me that she has a white screen upon start up each time she turns on (boots up) the laptop. I tried to boot the machine up to see what IOS version she has but can't get past the white screen. I trried moving the mouse and pressing arbitrary buttons to no avail.

Try booting from an installer DVD. If that works OK, then reinstall OS X.

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.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. 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.
d. 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 the technique in Step 1b, 1c, or 1d 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
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
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 11
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 12
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 13
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.

Intel Imac stuck at white screen and 3 beeps sound continously....

Intel Imac stuck at white screen and 3 beeps sound continously when power on. Pls help......

Well Barry, as for the Ram, all this while are install by apple technician since very day i bought iMac on july 2008. Just wondering What's actually went wrong..
Very first day I bought iMac, few days later, system cant even on. AppleCare Centre exchanged a new set of iMac.
two weeks later, i notice several dead pixels appearing on screen, call to log a case with them, later on, they changed a new panel.
After several months pass, been using happily with iMac... but since now, this problem occurs. So fastrating... My third time encounters problem with iMac. sign
Any suggestion? If not, I guess i have to bring this bulky iMac to applecare centre again. sign

Imac have black screen. Start Computer sound come on, no picture. The last time I used the computer I put it to sleep, it never came back. i tried everything that was suggested including puting in the start up disk. The disk would not eject. Some one

Imac have black screen. Start Computer sound come on, no picture. The last time I used the computer I put it to sleep, it never came back. i tried everything that was suggested including puting in the start up disk. The disk would not eject. Some one suggested how to remove it and that did work. Computer going to Apple hospital Tues. July 3, thank you for all the suggestions.

There is nothing wrong with the OS update.
Delete ALL your email accounts.
Restart Playbook
Put the accounts back and ensure they are all set with PUSH ON. Manual (push off) will burn battery.
Similarly delete your wifi connections and add back when required.
Turn off wifi is not connected to wifi.
Any "hunting for connection" in email or wifi will burn up battery.

White screen at start, eMac

I have an older eMac (probably about 7-9 years old, I bought it used). It was working fine this morning, but when I shut it down to take a nap and restartd it this afternoon I got a plain white screen and no action. I got the usual welcome sound, but the white screen never made its way to the usual desktop art. Is there any way I can get the computer restarted? I do have some of my startup disks, but I'd upgraded to OS 10.5 and added memory chips to the machine several years ago. I do have a newer MacBook Pro, but I like using the eMac at home since it has a bigger screen (I added an external screen when the monitor in my eMac unit died) and a better keyboard. I'd also like to reclaim the data on the hard drive, if possible. I live in a remote part of Alaska, so I can't walk down to a Mac store to get this fixed. Luckily, I have been backing up most of my stuff on an external hard drive. Does anybody have any suggestions (by the way, I haven't been able to get the disc drive slot to open since the white screen appeared).

Hello,
To open the tray try holding Mouse button down while starting, also, you can open the door at the top, look for a tiny hole to stick a straightened out paper clip in to open the tray manually.
If 10.5 be sure not to use a 10.4 or less Install Disc to repair the drive.
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, 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 at top of the screen. (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. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
Tough without the Install disc, but some things to try...
Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
/sbin/fsck -fy
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).
Resolve startup issues and perform disk maintenance with Disk Utility and fsck...

Does holding alt key at bootup show any boot options?

White screen upon start up

Hey sorry if this has been answered but im not in the mood to go scrolling through dozens of pages to find what im looking for.
So here goes. Today i decided it was time to set boot camp, however before i could do this i had to defrag as my imac is around 20mouths old and the drive looked a bit messy. (note : it worked absolutely fine) Defrag finished and my computer was back to normal use, i postponed setting up bootcamp for a day and shut the imac down. When i rebooted later the typical white screen appeared with the happy spinning wheel. HOWEVER underneath this was a loading bar that i have never seen before, this loaded to about 10% then went back to the start and got to about 30/40% before the computer shuts itself down.
WHAT IS GOING ON? please help im a university student a i desperately need tis to do my study.
PS i have tried the trick of unplugging (that is mentioned all over google) it didn't do anything.

Did you (or your defrag utility) verify the integrity of the drive before defragging? If not, sounds like your drive was probably damaged in the process. Try [repairing the hard drive with Disk Utility|http://support.apple.com/kb/TS1417]. Most likely this will not be adequate to get your computer back up and running - you may need to go so far as reinstalling the system - but it's a start.
