My Mac will not start up and I get a 3 tone repeated beep. What is this?

Whenever I try to start up my iMac all I et is a series of 3-tone beeps repeated endlessly and I can't get it to start up. Also now the apple repair disc is stuck in the drive and I can,t eject it.

Hold down the option key while starting your iMac
You should see a screen with some imagines of hard drives appear.
Press the eject key to eject the disk, then select your boot partition (likely named "Macintosh HD") and hit the return key.
If you still hear the three beeps, the computer may be unable to access its system memory. Preform the resets detailed in these articles:
https://support.apple.com/kb/HT3964
http://docs.info.apple.com/article.html?path=Mac/10.7/en/mh26871.html
Or try as den.thed suggested if you have recently installed memory into your computer.
If your boot partition does not appear when you hold down option and "Recovery HD" also doesn't appear, or if it does not allow you to eject the disk, you may be experiencing hardware issues. Try the above resets, and if they don't work, you will need to go to your closest AASP or Apple Retail store for service.
Good luck.

Give this a try:
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. 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 main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

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.

My macbook will not start up. It gets stuck on teh opening page with the apple. It was working fine and all of a sudden i cant get it to work. Does anyone know what could be wrong with it? Or, is there a bypass to the start up page?

You won't lose your files unless something goes very wrong -- which may already have happened. You absolutely must have a backup before you do anything else. If you don't already have one, boot from your installation disc and follow the instructions in this article under "Instructions for backing up to an external hard disk via Disk Utility":

Flip4Mac shouldn't have been a problem.
The Windows version of anything won't run on a Mac, the binaries are different. So no "PC Studio".
So the only thing I see is a Mac version of Kies, which allows you to manage your Samsung phone.
The spec call for a 10.5 or later, is very unlikely to work with 10.6.8 or 10.7, as there was some "changes"
Usually holding shift key while booting disables the third party kext files that cause the computer to freeze, which would allow you to remove the offending ones from your System/Library/Extensions folder.
Your remedy would be to hold c boot off the 10.6 installer disk (or hold command r boot if on 10.7) and simply overwrite OS X with a fresh copy (leaves your files and other programs alone), that will bump out the Samsung hacks in OS X itself, then immediatly software update to 10.6.8.
If you need replacement 10.6 grey disks then call Apple with a credit card and your serial number (about this mac >more info)
There is nothing you can do at this point without a fresh version of OSX 10.6, unless you know where all the Samsung hacks are and can remove them from Single User mode (aka root)

Well, you downloaded a bootleg copy of iOS 7 beta and have installed it on your phone without being a developer. It has bricked your phone and you cannot get help here because doing what you did has voided your warranty. Have a nice day.

Display "Application over 20MB" when I type OK button, the appearance will not go away and make me unable to open other applications, what to do and whether it must be restarted

display "Application over 20MB" when I type OK button, the appearance will not go away and make me unable to open other applications, what to do and whether it must be restarted?

The 20 meg message is the download limit for 3G. If you can't get rid of the 'OK' message then you can do a reset by pressing and holding both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
You should be able to download the apps by switching to wifi on your iPad or downloading them on your computer's iTunes and syncing them or dragging and dropping them over to the iPad device.

My Mac will not start up i have tried safe reboot and verify file from disk utility to no avail am reinstalling Yosemite but couldn;t do it to recovery and its taking hours any ideas please

Followed some instructions to reboot as will not start and its taking ages any ideas please

Slow down and write clearly. What you're writing doesn't make sense. You need to write exactly what the problem is, and make understandable. Otherwise, no one will respond to you help request.
This (I May have found solution in 7 Mac start u options every os x user should know on a forum , gives recovery mode etc I had started to try to download yosemite again but that's what was taking forever! So I stopped it going to try the 7 options listed if not appointment at Genius - note to all back up your work, pictures etc I will be debased if they cannot recover them...) is slang. We don't speak slang.

My Mac will not start up like normal and I don't knwo why

My iMac will not start up like normal and I don't know why. I tried to run Skype then nothing happend so I tried to restart my computer, but then it never loaded

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 boot failure is to secure your 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 your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into 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, boot 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. The easiest way to deal with the problem is to boot from an external drive, or else to 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 boot 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 boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot 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 booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot 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 your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot 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, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 6.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot 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 reboot as usual (i.e., not in safe mode.)
If the boot 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 your 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 reboot as usual.
Step 9
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 10
Repeat Step 9, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your 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 boot 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.
