21 "iMac 2010 with el capitan making a buzzing sound and won't start not

I have a 2010 21 "iMac running EL capitan who today suddenly makes a gurgling noise and he wouldn't do anything so I turned it off and tried to put it back on and it continues to make a buzzing sound, as soon as I press the bottom of the power to the rear it hums 3 times then stops and emits a 3 stops... on a black screen. All tips thank you

Three beeps usually indicate a problem with the RAM.

See > Startup on computer - Mac Support Apple tones

Sometimes, modules dispose and sometimes the modules go bad. Personally, I would check and/or replace the RAM modules.

If you cannot or do not know how to install or check the RAM for yourself...? Next, you need to contact your Apple Store or FSAA and book a service appointment. See > https://locate.apple.com/country

    Original title: Lenovo SL500 Windows Vista crashed with STOP error message and won't start

    Hello peoples,
    I just installed an iMicro Bluetooth adapter on my computer, and then I wanted to restart my computer. When I turned it on, loading like regular until right after the Vista loading screen, when the Blue Screen of Death (a blue screen with an error on this subject) flashed for about 1/2 second and then restarted my computer. Then he asked me if I wanted to load startup repair or simply start WIndows normally and I chose to start WIndows normally, but it's the same thing, so when the computer is restarted again, I chose the Startup Repair. He said that if I inserted an external device in my computer for me to remove it. But I had no external devices in my computer at the same time! I already pulled the iMicro adapter! So when my computer restarted again, I pressed the button Lenovo Care and charge of Lenovo Rescue and Recovery 4. (This is where I am now, typing away in the Opera browser.) I tried to find help, but could not find anythign useful so far. I installed for many drivers, updates, patches, etc. But none have anything to remove the blue screen of death. Now, after 7 hours, I really frustrated, and this is my last hope! (I don't want to save my hard drive and reinstall, because I paid more than 250 applications and more than 270 free programs on my computer! Of more, more than 350 iPad apps, of which a few are paid! Oh and 700 iBooks!)
    Help, please! I'm really desperate right now, and any help would be appreciated!
    Thanks in advance!

    PS I run Windows Vista Home Basic SP2 (I think) on a Lenovo ThinkPad SL500 (NOT SL500c!)

    PPS Lenovo all computers have this Lenovo Rescue Recovery 4, which is like an operating system of its own. It has a browser that you can install updates and other things. Right now I use Rescue and Recovery. Thanks again in advance and please answer my question! I had this problem for a week and I'm in school tomorrow! Thanks again!

    EDIT: The error message went like this:

    A problem has been detected and Windows has shut down to prevent damage to your computer.

    If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

    Check for viruses on your computer. Remove the hard drives newly installed on the hard disk controllers. Check your hard drive to ensure that it is configured and completed proeprly. Run CHKDSK /F to check for hard drive corruption, and then restart your computer.

  • Problem starting el capitan (sierra) - built-in keyboard and the mouse do not respond

    Hello

    I have a 2015 macbook pro (SSD 256, 16 GB of RAM last el capitan updated) with a wired problem.

    I use it mainly to a cinema monitor and I use wireless keyboard and mouse (office installation program), and of course as a stand-alone laptop when I'm not at my desk.

    When I put the laptop to sleep, everything works fine when I wake up.

    but, if I'm away from the office and I have to restart my laptop, here is the problem.

    The boot process is very very slow, there is no edge, and when I finally have the screen to unlock the safe, the keyboard and the touchpad do not react. Actually, that's not exactly true, they are so slow that they are unusable and get caught quickly, all gel. So I can't unlock and complete the boot. My laptop is unusable ;-(

    At this point, I get a message that if I forgot my password I just need to reboot by pressing the power button, and I'll be able to reset it.

    When I do this and aprΦs the dΘmarrage that more slowly than usual but ok, I get another screen with several options of problem solving. One of them is "keyboard not responding do not. When choosing this one, it asks if you want to remove safe. I tried and everything was back to normal.

    later, I delivered safe and I had the same problem again. I did the thing to be able to restart again and improved to sierra in the hope that it would disappear. However, the problem is still there.

    I thought I could try to restart my office to see if my keyboard and wireless mouse would still work. Indeed, even if responsiveness was not normal, I could unlock and fill the chest.

    I have the impression that my laptop always "believe" it is on my desk, linked to my screen (probably the reason why I don't hear the Bell) and to my wireless K & M.

    It's really annoying and I hope someone has a solution.

    Thank you very much

    best,

    Alex

    I'm having a similar problem with macOS Sierra which I didn't have with El Capitan.  I can possibly move the cursor on the power button and turn off (no), but I must be patient because the keyboard and trackpad are only for a fraction of a second, which only allows me to move the mouse slightly.  After he stop and start back up, everything is perfect until I tried another reboot, and then I'm back to the beginning.

    I tried to reinstall the operating system, reset the SMC, resetting the NVRAM, reboot in SafeMode... nothing worked so far.

  • Mid-2010, with El Capitan iMac turns off at boot

    I have submitted this before, but the thread is dead. I thought I would give it one more try before considering the shop. It starts, I hear the chimes, Apple comes on the screen and progress bar goes to about 60%, then it stops. It started this after I stopped him hard when the machine booted up during the night. It does not start in safe mode. I did the PRAM reset but only on the left side of the keyboard (seen anything recently to do from the right side, but it didn't really make sense to me). I tried recovery mode, run fsck, nothing works. Went to recovery mode to try to boot from the optical and player don't work - spitting just the DVD of return. I don't know what else to try.

    You probably have a hardware problem, I just make an appointment and take the service computer. If the computer does not start even in the recovery Partition that points the finger to a failure or defect HD in many cases.

  • problems when you install a SSHD on an old Macbook Pro (2010) with El Capitan?

    Swapped a HDD internal with a Samsung 250 GB SSHD and I have latency issues with

    video and audio.  El Capitan installed.  I omit something?  Is there something I need to do?

    Computers that can be upgraded to use OS X Internet Recovery

    If your model may use Internet recovery, do like this:

    Clean Install of El Capitan on a new disc

    1. Restart the computer. Immediately after the chime, press Command + Option + R until a globe appears.
    2. The Utility Menu appears in 5 to 20 minutes. Be patient.
    3. Select disk utility, then click on the continue button.
    4. When loading disk utility, select the drive (generally, the entry Out-bumpy) in the list aside.
    5. Click the Partition tab in the main window of disk utility. A panel will fall.
    6. Set the GUID partition scheme.
    7. Define the type of Format Mac OS extended (journaled).
    8. Click on the apply button, then click the fact when it is active.
    9. Quit disk utility and re-enter the Utility Menu.
    10. Select reinstall OS X and click on the continue button.

    This should install it the version of Mac OS X that has been previously installed when the computer was new.

    [Permission to use any part of the foregoing has been granted by khati, exclusively, to theratter.]

    Otherwise, you must use the original disc that came with the computer, boot from it. Use utility disk to erase and repartition the disk for OS X, and then install the version of Mac OS X that comes with it. Update the version of Snow Leopard to 10.6.8 using the Mac OS X 10.6.8 v1.1 updated Combo updater. You can then access the App Store to download and install El Capitan.

  • Lightroom 6.6.1. won't start not on a Mac after upgrading OS to El Capitan

    I use Lightroom since version 3 and never had a problem like this. I've updated my iMac with OS X El Capitan three days ago. After the upgrade I wanted to use Lightroom 6.6.1 but it does not start. It seems that it will start but suddenly it closes without any messages. The next time I try to start Lightroom again it closes immediately, I don't even see the first screen displayed every time that we start a program of Adobe.

    Post edited by: João Alves

    Finally, I could start Lightroom 6.6.1. The problem was with my synched on Google Drive folder structure. I decided to sync less files instead of all records and apparently it was missing some important files to LR 6.6.1 work.
