System stuck on white screen and beeping sounds

Power button turns screen from black to white and computer starts making intermittent beeping sounds. Tried SMU reset, hard reset, disconnecting cables but the problem stays the same. Any other suggestions.

I had a similar problem on my 24" iMac purchased Dec 07. It was OK from a cold boot, but would go to the white screen and 3 beeps on any reboot. If I held down the Option key I could select the only disk and it would boot OK. I tried detaching all external disks - no change, ran HW diagnostics, - showed no problems. Ran disk verify/repair from CD, no errors. System info showed no problems with POST or the DIMMs.
I first re-seated both 1Gb DIMMs - no change.
Swapped the DIMMs into opposite slots - no change.
I removed one, fixed the problem.
I put in the suspect one by itself - problem returned.
This is original RAM that came with the system, trying to get the suspect DIMM replaced now, but system is OK for the moment on 1GB.

  • HT1338 i cant get in to os system. the screen just stuck in white screen and apple logo

    i can not get in to my os system. the screen just stuck in white screen and apple logo

    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
    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.
    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.
    Step 3
    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 damaged and the drive is probably malfunctioning. In that case, go to step 5.
    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 4
    Sometimes a boot failure can be resolved by resetting the NVRAM.
    Step 5
    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 6
    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 7
    Repeat step 6, 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 backup.
    Step 8
    A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
    Step 9
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

  • My MacBook Pro 13 won't start has white screen and beeps

    I used my MacBook pro lastnight and worked fine. Tried to turn it on this morning and it won't start. Does sound like it is going to then before login screen shows ur goes to a solid white screen and beeps every 7 seconds. Need help school is about to start again.

    Check this out.
    I think you have bad RAM, so either you've recently put in new RAM, knocked some RAM loose from the socket (really hard to do), or the RAM went bad (maybe).
    You might need to see a real tech.
    Upon further review, I think your MBP has a serious problem.  You need to take it to an Apple Store for repair.  If you bought it within the last 12 months, you will be able to get warranty service, as long as you're not at fault.

  • I downloaded the new itunes update and now no videos will play. I get a white screen and no sound. also a bunch of songs i have purchased no longer play.

    i have a bunch of files that can't be located and some songs that i purchase that when you click on them they skip to the next song. also all my videos, movies and tv shows i purchased come up with a white screen and no sound they show they are playing 

    "Add Folder to Library" is still where it always was, in the File menu.
    The new "innovation" is that the File menu is hidden by default!  But you can reveal it by using CTRL+B.

    I used to install the rEFIt to boot with win7. When I deleted win7, I didn't uninstall rEFIt. Nothing wrong with it. One day after I watched movie in full screen,I pressed esc to quit. Then I found the touchpad didn't work. I can't turn off air. I just pressed power button for a little while. It rebooted, then my nightmare just began...
    I have tried everything, PRAM, command+R, literally everything. No change.
    But when I plug a CD-ROM with USB, I can only here one BONG, just once, then white screen, Like waiting for something...
    I took it to a service center in China, they told me the CPU had broken. SInce it's one month out of warranty, they wanted to charge me for like $250....
    I really don't think that's CPU's problem. I checked the history, it seems like somebody else also had the problem before.
    Can anyone give me some hints??? Thanks!!!!!! Or I have to take it back to America to check....

    Impossible, there are zero, as in none, zip, nadda viruses for OS X. If you have viruses on it they are for MS Windows and will not affect OS X. I suspect the hard disk has crashed, if you have backup then it's not a big deal to have it changed, just take it into your local Apple Store or AASP for service. If you have not been backing it up you may be in for a painful lesson on why backup is critical.

  • My ipod nano has a white screen and beeps twice, Can i fix it?

    I left my ipod in my pants and they went througth th washer and dryer, I put them in white rice for two days and it still has the white screen and beeps twice, Can i fix it?

    Hello Emmuhhlieee,
    Thanks for using Apple Support Communities.
    For more information on this, take a look at:
    iPod nano (6th generation): Hardware troubleshooting
    http://support.apple.com/kb/ts3474
    Display shows a white screen
    Try putting the iPod into disk mode:
    Reset the device (press the Sleep and Volume Down buttons simultaneously until the display turns black—about eight seconds).
    When the display turns black, hold down the Volume Down and Volume Up buttons simultaneously until the device enters Disk mode.
    While the device is in disk mode, sync it to iTunes and try to restore.
    Best of luck,
    Mario

  • Ipod nano: white screen and beeping twice

    I have an ipod nano 4th or 5th generation. When I try to turn it on, it displays a white screen and beeps twice. I have tried the basic things: toggling the lock switch, holding down select and menu buttons simultaneously, doing that and then holding down the play and select simultaneously. Even restored it. Updated all of my itunes software. Still broken. What next?

    Hi
    It seems to be ok now... I had to go out and it ran out of battery, when I switched it back on it  appears to be fine.
    If it happens again (hoping that it doesn't!) and i do the reset.. will that remove all the music that's on there?
    Sorry for the ignorance
    Thank you for the answer

  • HT201412 my ipod touch 4g is stuck on white screen and none of the buttons work and holding home and sleep button doesnt work either

    hi im abishek and my ipod touh 4 g is stuck on white screen and holding he power and hoe button doesnt work.what should i do?????!!!!!
    and also my ipod doesnt show upp on itunes so i cant restore it.

    Try:
    - iOS: Not responding or does not turn on
    - Also try DFU mode after try recovery mode
    How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - Try on another computer
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • Stuck on White screen and pinwheel after installing Leopard

    Tried to install Leopard last night, everything appeared to go fine. But this morning when I woke up the screen was stuck on a white screen with apple in the middle and the grey wheel below it (yes it is moving) so I think the cd just wont finish running. Problem is can not get the disc to eject or the computer to do anything. Have tried everything I could fine on website including turning off and unplugging for 30 minutes but when turn back on still get the same screen. Help, Im new to Mac and very frustrated. Thanks

    When you turn on the computer, hold down the mouse button. The disk should eject.
    Did you notice if the disk passed the selfcheck.
    Leaving an optical drive running actively overnight is not a good idea.
    During any install, it is always best to babysit it. That way you can quickly spot anything unusual and take care of it immediately. You can also see the progress and read any information screen that pops up.
    After you remove the DVD, the system may still not boot for other reasons, but if you have problems, restart it and hold down the shift key to enter the safe mode and see if it boots.

  • X200 black screen and beep sound when power module is plugged on and off

    Hello,
    I have the following problem. Today I turned on my X200 without power module, and when I plugged in power - the screen starts to flicker. This was not before, and I am using my laptop only during a week.
    After that I turned on the laptop with power module, it was OK, but when I plug out and plug in power module, computer makes "beep" sound and becomes black for a second. Is that normal behavior? 
    Thank you!

    does your battery hold a full charge. is it in good shape.  is your machine under warranty. you could try support, but they're probably just gonna tell you to open a service claim.  another thing, did it always do this or is this something that just started. did you just download any updates and this started right after. or did it just start doing this for no reason.

  • 2011 Macbook Pro Stuck on White Screen and Won't Shut Down

    Greetings,
    I just received a 15 inch Macbook Pro with a 2.2 i7 processor earlier today. On my previous computer, a 2009 MB P with a Core2Duo, I've had a shutdown issue on it for the past week or so: when I click the power button, and confirm the shutdown, the computer would start shutting down as normal, however once it reached the white screen with the spinning loading symbol at the bottom, it just got stuck on that. As I've transfered my old data to my brand new computer, I'm still having the same issue with it. I was wondering if this was due to a worm, or some software incompliancy? If anyone could shed any light, I'd be greatful.
    Thanks.

    Were you using any of them when the issue occurred (or just prior to it)?
    Have you looked for updates on all of them?
    If you want to do some digging, open Console and look at the logs at, and just prior to, the time of the issue.
