Computer wont start - did the PMU RESET - will turn on without monitor

PROBLEM :
I have done a search....about 30 pages....read thru approx 70 posts and external links....really need HELP. PLEASE.
I just moved recently. Shut down the computer (but did not park the drives). 48 hours later, I set up my powermac quicksilver G4 - and it will not turn on.
WHAT I HAVE TRIED :
Zapped the PMU - 5 seconds, then the power button for 5 seconds with the cables all removed.... nothing
Zapped the PMU - 5 secs and powerbutton 5 seconds with the battery removed
and the computer would go on ONLY WITHOUT the monitor being attached....as soon as I plug the monitor cable back in, it shuts down immediately (as if someone pulled the plug)
Zapped the NVRAM next
Zapped the PMU again
Took the battery to Radio Shack - it read 3.71 (so it is good)
QUESTION :
Does anyone know what I can do? Please....and suggestions!
TIA

I have Apple Remote Desktop (which may or may not change the playing field)and I am able to login in with my laptop, and shutdown etc....
I just tried this.... to see if there was anything I could do remotely.
--> Is there something that can check the video card that I can run on my computer remotely?
I FOUND ANOTHER THREAD with a user with the same problem....is there anyway to contact this person to see what was done to solve the problem?

  • E540 After BIOS update the computer wont start

    Hi!
    After I did an BIOS update from windows the computer wont start. Only the green FN key and the red "i" in the word ThinkPad lights up!
    I can't access BIOS.
    Tried tho remove the small CMOS battery for an minute

    If these long boot symptoms, following the BIOS update occur, multiple customers have reported success in resolving them  by disabling Intel AMT and setting the security chip, TPM, as active in the BIOS.
    Steps to disable Intel AMT and enable TPM settings as below.
    Boot into BIOS
    Select Config
    Select Intel AMT
    Press Enter key on Intel AMT Control and select Disable
    Press ESC twice
    Select Security
    Select Security chip and select Enable
    Press F10 and click Yes.

  • HT201406 My phone keeps trying to facetime randomly during phone calls, it will also mute itself and put itself on speaker phone.  Anyone else have this problem?  I did the factory reset and I am still having issues.

    My iphone 4 will randomly try to facetime, mute itself, or put itself on speaker phone during a phone call.  I did the factory reset, but I am still having this problem.  Does anyone know what may be wrong, or has anyone else had this problem before?

    I have the iPhone 4s on Verizon and never had this problem until I recently updated to iOS 7.0.2. I have the same case on it for several months. Yesterday, when I was talking on the phone with someone, it appeared as though I lost the call. But when I looked down at my phone, it was trying to Facetime with someone in my contact list. It happened again today. Different person, but both people have names that start with "A", so they are at the top of my contact list. Very frustrating! So, obviously updating to the latest iOS either did not help or was the cause of the problem.

    i upgraded to yosemite last week, now my computer wont start. it stops at white screen with apple logo. what do i do?

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
    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 a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
    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 in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is 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 11. 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.

  • My computer wont start!

    My computer wont start and i dont know why!

    If a SMC reset fails to bring life to the MBP, make an appointment at an Apple store genius bar for a free diagnosis.

    I assume you have a functioning power adapter attached to your MBP.

  • My iPhone 4s was playing music now won't on my sony dream machine how do I fix. "This device is not supported by this I-phone".  I have turned  off phone unplugged sony and did the pin reset on bottom.     Help please I need my tunes

    My iPhone 4s was playing music now won't on my sony dream machine how do I fix. "This device is not supported by this I-phone".  I have turned  off phone unplugged sony and did the pin reset on bottom.     Help please I need my tunes

    Try plugging it up to your computer and launching iTunes and either resetting it to factory settings or resetting to last sync. Hopefully it just noticing it's plugged up to iTunes will fix it. This happened to my friend once and all she had to do was plug it into her computer and that fixed it.

    I am having problem downloading application on Mac app store, when I try to login and start downloading the application, it will say "Your device cannot be verified"

    Back up all data before proceeding.
    Step 1
    Triple-click anywhere in the line below on this page to select it:
    /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
    Right-click or control-click the line and select
              Services ▹ Reveal in Finder (or just Reveal)
    from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and test.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination  command-C. In the Finder, select
              Go ▹ Go to Folder...
    from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
    Log out, log back in, and test. If there's no improvement, continue.
    Step 2
    Reset your computer’s PRAM.

  • Computer wont start after apple logo shows up..

    I have a friend who owns a MBP 13 Late 2012, and suddenly he explains computer after he shut it down, the gray screen shows up and apple logo too, but never enter to the OS.
    I have had this problem with a 2009 iMac in the past and they told me it was a problem of humidity and or dust, and so they had to change the Motherboard.
    Have any one experienced this ?
    I even did the PRam reset several times with no luck, actuallu It wanted to start (get into the OS) but MBP kept with little spinning circle.
    Any thoughts?

    So I received the MBP, and did the Command R to get to recovery mode, and after the World spinning, I got this Message: www.apple.com/support and then -5010F ... (image 1)
    Power it off and reboot it with OPTION key, and selected Macintosh, and after that the Apple logo shows up with the little circle spinning infinitely.
    What do you think? Doesnt go any further than this: (image 2)

  • My computer is not recognizing my ipod shuffle.  The computer says to use the ipod reset utility.  When I tried doing this it told me that it was for a 32 bit version which I obviously do not have.  My computer is only a few months old.  What do I do now?

    My computer is not recognizing my ipod shuffle.  The computer says to use the ipod reset utility.  When I did that it came up with another message that it was only good for a 32 bit version.  I guess I do not have a 32 bit version.  I just purchased my computer a few months ago and it uses the windows 7 operating system.  What do I do now?

    Not sure if this helps:-
    The music files, were they bought from your iTunes account or did someone gift them to you after buying from the iTunes account? If they are yours you can download them again if you clear or de-authorise the ipod, it has to be done by whoever gave you the ipod to do this (the registered  owner). If they were bought for you on another itunes account I don't think Apple let you use them as they are copyrighted and they don't belong to you, they belong to the person who bought them. If the music files where ripped from music cd's then click and drag them to a new folder on your desktop and have the person who gave you the ipod to de-authorise and unregister it. Then you re register it and put your files back from your desktop folder in your iTunes folder and synch. Hopefully that would work.  Any files which you did not buy, I would not know how get around this, best bet is to take it to you nearest Apple  Store and explain that they were gifted to you and ask how you can use them.  The best way to gift music files is to buy the gift tokens and give these. Hope above helps.

  • Computer wont start up

    So today I went to start working on my LR and FCPX projects and when I got to the office for no reason at all my computer wont start up.
    I've tried holding the "shift", "command" & "V" key from what I read to do, and now I get a black screen which pretty much said what the grey screen said.
    This is the strangest thing.

    According to your profile your Mac has v10.8 installed.
    Startup your Mac while holding down the Command + R keys so you can access the built in utilities in OS X Recovery
    From there you can repair the startup disk if necessary or restore OS X.
    Hopefully you had all your important files backed up in advance just in case.

    You did import these important photos over to an alternative storage medium, just like you would with any digital camera, right?
