24" Imac shuts down during startup, HD replaced

So my iMac (running Mavericks) was running really slow and wouldn't respond often. It got to the point where it was freezing up or getting the spinning wheel all the time. I assume the HD was failing and bought a new one. I originally had a WD SATA 1TB drive in it (original from apple) So I basically ordered the same thing from Amazon. A WD SATA 1TB. I followed all instructions on iFixit for HD replacement. Overall the installation went fine. Not my first time under the hood of one of my Macs. I ran the recovery mode, formatted the new drive and restored from the time machine backup. All going smoothly. Now when it boots I get the gray screen, apple logo, spinning gear then complete shut down. Zapped PRAM, rest SMC. I'm at a total loss what to do next. PLEASE HELP!!

Try to boot up in Safe Mode. Hold down the "Shift" key as soon as you turn on the computer. This will force a check of the directory, turn off extensions and login items and more.
If that doesn't work, I recommend booting from the Mac OS X install disk and using disk utility to check the drive. Slide the install disk in the drive and then restart holding down the "C" key. Keep holding it down until it is booted up. From the menu select "Disk Utility", then highlight the hard drive, then click "Repair Volume".
Lastly, if that doesn't work - go get a copy of DiskWarrior which is known to fix just about any hard drive problem. Everybody should have a copy of this on hand anyway.
Good luck!!

  • IMac shuts down during startup

    My 1.8GHz 20" iMac G5 will shut down soon after I hit the power button. Sometimes I get a grey screen for a few seconds before it shuts down and other times I only see the power light before it shuts down. You can hear things running but I am not sure if it is the fan, hard drive or both.
    I took the back off and the first three LED's seem to check out okay. I also reset the PRAM to no avail.
    My iMac had been in storage for a while and seemed to boot fine when I first tried. I plugged a portable hard drive into one of the USB jacks on the keyboard and got an error message about USB overcurrent. Before I could even finish reading the message and react to it the machine shut down and hasn't been able to start ever since.
    Does anyone have suggestions on a self help fix before I take the machine in to the Apple Store?
    Thanks,
    Sean

    How long? It's possible you may need a new battery?

  • Shuts down during startup

    IMac shut down during use. On startup I get a progress bar on white screen then shuts down again. Any thoughts?

    Hi Eric
    When I put in my system DVD (I'm assuming that's the one with the operating system install) there was no change.  I still hear the computer power up, I get the white screen (and now hear the DVD churn), get the Apple logo, get the white bar across the bottom of the screen that shows progress, and then poof, the computer shuts down (with my operating system DVD in it).
    Cheers,
    Chris

  • MacBook Shuts down during startup

    My MacBook started acting slow the other day and then today when I started it up, it was in a constant lock up with a spinning pin wheel. No force quit commands or anything would work. So, I restarted it and now after the Grey screen with the Apple logo, the MacBook shuts down. The only thing I can get running is by holding C with the Leopard disc in there.
    I tried to run Disk Utility from there but everything failed. I'm assuming I need a new hard drive? Is there anyway to save data from within the Leopard disc bootup? Maybe over a network?
    Thanks

    Hello,
    I am having this very same issue. It shuts down during startup. I can boot into Windows, and using the Leopard startup disc, Disk Utility could not work any magic. I do not have a second Mac or access to one for any backup purposes. I have no idea what else to try, does anyone know something besides backing up through firewire, on how I can either save my computer's data or resurrect the drive? Thank you for your help.

  • My imac shuts down during the startup process - possible startup file corrupt..??

    startup process begins normally...
    grey screen - then the apple - then the spinning wheel -
    sometimes shuts down during spinning wheel, sometimes it gets to the blue screen then shuts down

    Zap the PRAM and Reset the SMC, then try again. If no go, Bboot with the SL install disc, launch Disk Utility, repair the disk, and restart normally. If that doesn't do the trick reinstall SL and then run Software Update if that does.

  • IMac shutting down on startup - Can't enter safe mode as wireless keyboard doesn't connect quickly enough

    Hi all,
    I was planning to use bootcamp to install Windows 7 on my mid-2010 21.5" iMac.
    Bootcamp recommended I usk disk utility to repair the drive. I had a snow leopard install disk in the drive, (I didn't realise Lion already had it's recovery tools built in to the hard drive.)
    Disk utility said it can't repair the drive and recommended I start backing up my data (because the hard drive could be about to fail). Fine, so I restarted, with the intention of backing up everything (all my work for the last 12 months). So I press the power button, grey screen comes up, then the apple logo, then a progress bar appears (found this odd at first, but later found out it has something to do with disk utility and a bad hard drive) it gets to around 20% and then all power is cut from the iMac and the hard drive stops/everything powers down.
    Now, I can't seem to get my iMac to boot into recovery utilities or into safe mode because it doesn't connect to the wireless keyboard in time before it shuts down. So, if I use a wired keyboard (I have a dell USB keyboard that I can take from the office), will I be able to boot into safe mode?
    Also, if the disk in drive is causing the problem, then I can't remove it because the wireless keyboard won't connect/register any keypresses.

    Ok so, status report:
    Wired keyboard is non responsive when I plug it in before/during boot. So i guess it needs to be plugged in before the iMac shut down. That's that out the window.
    Plugged in headphones and I can't hear the startup chime so don't know when to start holding buttons.
    To make matters worse, the wireless keyboard is no longer paired with the iMac, getting a green blinking light which indicates it wants to connect to a computer or device.
    So I can't enter any commands whatsoever, can't remove the disk in the drive or boot safe mode. It's my worst nightmare.

  • Computer shuts down during startup

    Hey everyone,
    it shames me a little to ask for help about computers because I am usually ok with doing this stuff myself.
    This time, however, I cannot seem to fix the problem indefinitely.I need a laptop for school and cannot afford another so any help would be greatly appreciated!:
    I will just point the facts out:
    After a few years use (two) it now shuts down during (windows) startup.
    I ended up cleaning the Heatsink/fan yet the problem persisted.
    The model is a Toshiba Satellite A200-PSAF6A.
    I am no longer under warranty.
    The school techs cannot help me.
    A few oddities that I noticed:
    It starts up fine when the power plug isn't plugged in.
    It starts up fine with the power plugged in only in safe mode.
    Using CCleaner and Defraggler temporarily fixed my problem (for about 5 minutes or so).
    I hope that you guys can help me. It's just annoying that I cannot fix this myself..
    If any further information is required please just ask and I will reply with as much haste as I can under my current circumstances.
    Thanks,
    Norak.

    During a "cold start" I may get up to the windows login screen and then it shuts down and restarts. (sometimes it doesn't make it to the windows screen and turns off to restart). Then it will start to load windows and the little bar at the bottom will be loading windows and then freeze. I would have to hold the power button down to turn off and restart. Then I start windows normally and it usually works OK, sometimes I have to do this step again, but eventually I get into windows. Then if I shut down and restart it starts up fine, unless I wait for it to cool down.
    Since this started happening, I have reinstalled vista 32bit to out of the box condition and updated to the latest bios, to no avail.
    Computer has always run hot since new, seems to have very poor cooling. But the fan operates, most of the time on full boar.
    Do you think this is a software issue or a component issue, or cold joint.
    BTW it will not shutdown at all if I keep the computer in the F12 key settings area,im not sure what this place is called, but you choose to boot from cd here.
    Okay, this is weird and I'm not sure if this has anything to do with what I had mentioned earlier. I was having some issues with my DVD drive, it was rattling bad and the spin off time was off causing coasters on almost every blank DVD, so I had the thing sent in for a replacement. They put in a new DVD drive, checked the status of my BIOS (V 4.2 which I had all along) and returned the unit back to me sometime around April 22, 2010 -- ever since the thing was working fine. I'm not sure if the bad drive had caused the unit to work erratically.
    Before it was sent in, the issue was of course with the DVD drive, the startup then shutdown problems, plus a whole plethora of other small problems which I didn't bother to mention on my first post. For instance; the illumination lights that controls the media -- sometimes they would not turn off when I shut my computer down. The light stays on even after the computer powers off and I'd have to unplug the AC power cord for the lights to completely shut off.
    My initial problems with the laptop was:
    Media lights won't go off,
    DVD drive rattles very loudly and burns bad media,
    Shutdowns during startups,
    The screen housing would creak every time when I wanted to adjust the position (this happens when I adjust it slowly).
    After they replaced the DVD drive, everything seems to work fine. It's been almost two months now and I haven't had issues with any of the above mentioned problems.

  • IMac keeps shutting down during startup loading bar under apple sign

    My electricity went out and came back on a minute later. When my computer started up again the font was back to original factory setting. I then restarted my computer and every time it would load up it would shutdown. The computer chimes and then reaches a grey screen with an apple sign. Below it is a loading bar. This bar loads about 10% then goes back down and loads from 0%. A couple minutes later it shuts down after staying at 0%. It keeps doing this routine every time I start the computer. I then did a command s and rebooted the computer to factory reset it. The computer still shuts down and has the old habit of reaching 10% and 0% with the loading bar but now after the loading bar is at 0% it then disappears to the Apple sign and a loading circle. It then shuts down again. This iMac was originally 10.6.8. but i believe i updated it to 10.9.4 and was purchased new around 2008. I also tried to put in a CD with Firmware Restoration CD 1.7. but that didnt work. Can anyone help? or has anyone had similar issues?

  • Desktop G5 shuts down during startup

    Just sold our Desktop G5 to my in-laws. (It has always worked well for us.) Put 10.4 on it and everything has run just fine for a couple months. All of a sudden, it turns off during startup. It tries to restart, probably because I put the settings to restart in case of power outage. It sometimes gets to the desktop, even starts to open some applications as usual. Then other times it turns off during startup, only getting as far as the gray apple startup screen. We have changed everything we can such as different electrical outlet. (grabbing at straws.)
    It did have a cd in it but when managed to get it out. This had no effect on the problem.
    Also tried resetting SMU, with no effect on problem. Also held down option to get to chose startup disk while the 10.4 cd was in drive, but still does the same thing. Held C down too to force it to cd but did not work....same problem.
    Thanks for your help.

    I have a Powermac G5-I only have in the computer what was factory installed. The computer is a little over 5 years old. The problem started after I booted up and logged in. My desktop and pointer were frozen. I could not escape and I tried to shut down doing a force quit. No Luck. I eventually had to unplug the computer from the wall. Upon restarting the computer, when it came on, all I got was a gray screen with the Apple logo. After about a minute of this, The internal cooling fans would come on full blast. I also tried booting from the start-up disk (I had to install the disk manually, because the drive would not respond to the key command) with no luck. I have taken it to the Mac store. Their conclusion was it could be the motherboard or the CPU's, but they weren't certain either. Do you think it could be possible that it's not the CPU or Logicboard? The expense for replacing both, almost doesn't make it worth it. Any ideas?

  • Mac Mini shuts down during startup after update

    I've got a Late 2009 Mac Mini running Snow Leopard Server. Occasionally, it takes me awhile to restart after updates, so this could be due to the most recent update or possibly the combination of the last two...
    I went into my office, saw that there was a Safari update and decided to let it do its thing. When I came back 30 minutes later, my machine was off. I turned my machine back on, got the gray Apple screen with the spinning cog and the progress indicator for the update. A little over 10% through, the progress indicator reset. No biggie, I figured. Second time it got to the same point, it just shut down. Nada. When I restart, it does the same thing.
    I've tried resetting PRAM.
    I've tried resetting SMC.
    I've tried booting in safe mode, but that isn't working at all – just does the same thing as when I (fail to) boot normally.
    Everything but one of my screens and my keyboard is disconnected. ****, I even tried booting without either one connected (I just waited to see if it would turn off), and it failed.
    Can't think of or find anything else.
    Anyone?

    Humm.. you'll need to startup from your System Install Disc to test, repair or restore from Time Machine.
    Some options for Starting up from your Install Disc include:
    1. in an External Optical DVD Drive.
    2. from another iMac in Target Disk Mode.
    3. from a copy on a Thumb Drive or External HD.
    It's to bad that you are using Time Machine on the second HD instead of a clone with Carbon Copy Cloner - Home or SuperDuper! that you could boot from for testing, repairing and/or restoring.
    If none of the above helps?
    There is one good thing about a Mac Mini, it is much easier to tote into the local Apple Store or AASP than an iMac. see > Apple - Support - iMac - Service FAQ

  • Old iMac shuts down on startup

    Was hoping to help a friend erase his old iMac disk and reinstall OS so that he can recycle it, but it hung up at finding the hard drive on reinstall and then after quitting Install, it now shuts down on every startup. I've tried resetting PRAM, hardware test, etc., restarting from install disks with no success. Any suggestions?

    Try holding down the option key then power on. This brings up the startup manager. Click on your hd. Click on right arrow key.
    Sometimes if volumes don't appear in Startup Manager (what you get when you hold down the Option key at startup), you need to reset the Mac's PRAM, NVRAM, and Open Firmware. Shut down the Mac, then power it up, and before the screen lights up, quickly hold down the Command, Option, P, and R keys, until the Mac has chimed twice more after the powerup chime. Then, before the screen lights up, hold down Command-Option-O-F until the Open Firmware screen appears. Then enter these lines, pressing Return after each one:
    reset-nvram
    set-defaults
    reset-all
    "The reset-all command should restart your Mac. If so, you have successfully reset the Open Firmware settings."

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    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. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually login 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.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

  • Mac mini shuts down during startup

    Lately my Mac mini running osx lion got really slow and then when I shut it down for the night the next morning I tried to boot it up. It didn't boot up after 2 hours of grey screen and spinning wheel. I tried clearing my NVRAM but nothing happened. After that I tried to repair the disk but it said "cannot repair disk, backup as many files as you can and reformat the disk". After that I tried to reboot again and After about 30 seconds it shut down. During those 30 seconds it was normal except for there was this loading bar at the bottom. I have no Mac osx install disk because when I upgraded I just did it through the app store. Is there any way to backup my files without being able to use my computer?

    See if the Mini will boot into Target mode...

    If so it shoud appear as a FW drive the other Mac, we can check the system logs on the Mini for clues, or perhaps Repair the Disk if the other Mac is same OSX or newer.

  • Support direct3D graphics, 3D PDF toolkit

    It would be nice if in Acrobat's 3D tools, it would support both OpenGL graphics based models and Direct3D graphics based models. I use Autodesk Inventor 2011 as my 3D application.  Adobe does support some Inventor files, but none after about the 200
