Power mac G5 turns on but will not boot up

Hello,
I have the last power mac G5 quad core made before apple switched over to intel. I have not used he computer in about 3 month and it worked fine when I put it into storage but when I tried to turn it on today it will not boot up.
There is constantly a yellow light on near to where the RAM snaps in even when the computer is off. (this is the 3rd light up from the bottom and the only on that is on at this point)
When I press the power button a red light turns on for about one second. Next to this light are the words LED806 Checkstop and it is offset to the right of the other lights a little bit when looking into the side panel of the computer. This light also lights up briefly when I press the power button to turn off the computer.
After pressing the power button another red light turns on just above the yellow light that is always on and the screen is still black. Then the screen eventually turns grey with the apple logo as it normally looks except some of the pixels are off colored a bit in square patterns across the screen. When this happens a green light turns on just below the yellow light. Now there are three lights on all at once.
Next the screen briefly turns light blue and then a little darker shade of blue and the computer will not boot up or go any further than this point.
Can anybody tell me what is going on here and is there any way to fix this?
Is there any way to reset or reboot the computer this the install disk?

Hi Mike,
LED 1—CPU A:  red—contact Apple or an Apple Authorized Service Provider
LED 2—Overtemp:  red—contact Apple or an Apple Authorized Service Provider
LED 3—Power On:  red—the main power is on
LED 4—Trickle:  yellow—Power Mac G5 is plugged into the wall correctly
LED 5—Open Firmware good:  green—no problem
LED 6—CPU B:  red—contact Apple or an Apple Authorized Service Provider
LED 7—Checkstop:  red—contact Apple or an Apple Authorized Service Provider
Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...

    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.

  • My ipad turns in but will not boot up. screen stays blank. I've tried resetting it and rebooting from itunes. It says it is done but the screen still stays blank. The apple icone will show up intermittetly.

    I turned on my ipad after charging it and the screen went blank. I tried the home button and on off button and that did not help. I went to iTunes and rebooted the ipad and restored it and it asked me to reboot from the ipad but the screen is still blank. It will go to a blue screen if I hit the on/off button. What else is there to check?

    If you restored the iPad, there is nothing else to check. I suggest that you make an appointment at an Apple Store Genius Bar and let them evaluate your iPad.

  • MacBook Pro Turns On, But Will Not Boot

    I recently have had trouble with my MacBook Pro (2.4GHZ Duo Core purchased in late '07).  Last night before I went to bed I put my computer to sleep after normal usage of my computer.  I did not update anything such as firmware or progams in the past few days.  I had it connected to a WD external drive and an external monitor as I have for months.  When I went to wake up the computer this morning it would nothing appeared on the screen as it normally does.  I waited and tried different things, but no luck.  After a minute or two, I just turned it off by holding the power button down.  After a moment or so, I turned it back on.  The cd-rom drive spun up, but the computer did not post (chime), hard drive seemed not to be active, and nothing appeared on either the external display or the internal LCD.  I then turned off the computer again.  I disconnected everything, removed the battery for a few minutes and then tried to start it again.  The same result appeared each time: cd-rom spins up, no hard drive activity, no display.
    I tried various things that was suggested in the Apple Support area such as resetting the PRAM & SMC, as well as trying to get it to boot in safe mode and entering the BIOS.  Nothing.  Before I take it into the Apple store to have it looked at since it is very far away, I was wondering if anyone had any input on what could be wrong and if I am able to fix it myself.  Thank you.
     

    It's possible that you have the NVIDIA problem:
    http://support.apple.com/kb/TS2377
    Not really sure why it won't boot at all. People have reported suddenly getting no video at all, but I think they usually do get the startup chime.
    Probably the best bet is to make the trek to the Apple Store, as this sounds very much like a hardware problem. They should be able to test specifically for the NVIDIA problem.
    Good luck!

    Try booting in Safe Mode by holding your Shift key down when booting. Also, try holding the eject key down when booting to eject the DVD. If you plug a mouse in and hold the clicker down when booting, that should eject the DVD.

  • My macbook pro will turn on but will not start up.

    My macbook pro ['08 Silver keys] will turn on but will not start up. Screen is black and keyboard is unresponsive, besides power button. Help!

    ugh, no chime is not good, as that means it is not getting past the firmware POST phase.  Is the sleep light blinking fast?
    One thing to try is to access the RAM slots, remove, then replace and reseat the RAM.

    Yes the original Install Discs can be replaced for a nominal fee. Call AppleCare, you will need a credit card and the serial number of the machine. You can use the AppleCare Contact Info for the phone number on your part of the planet.

    My bad Eric. The startup preference recognizes the primary as a 10.8.3 startup volume but when u select it the system does not boot. I can only boot from my external backup drive

    Yes, This is a New Build, though Windows XP is already on the Hard Drive From a Previous Build. I Had a K8N Neo Platinum Motherboard with ATHLON64 3400. MB caught the hiccups and I changed everything out. So My Hard Drives have to be reloaded but not wiped??
    Yes, that is necessary. Also leave only one HDD temporary where you planing to install your OS, when installation is done then attach your other HDD(s).
    "So My Hard Drives have to be reloaded but not wiped?"
    No need to be wiped, only Windows re-installation.

  • My mac has full battery but will not turn on, instead it releases a tone instead. three low rings, why?

    Hi i have a mac book pro, older model. my battery is full but will not turn on. instead it play a tone of three sequential low toned beeps over and over again. ive have this problem before, thought it was just a sighn of over heating because id let it sit for a few hours and it would start up again. now its been off for a week and still the same tone with no responding at all. please help i dont understand why at all.

    #00 Phillips driver is needed to access the RAM modules.
    Take out the modules, clean the contacts with alcohol and make certain that they are firmly seated.
    Ciao.

  • How can I link my iPad Air and iPhone 4s via Bluetooth, please?  They haveBluetooth turned on but will not find each other.

    How can I link my iPad Air and iPhone 4s via Bluetooth, please?  They both have Bluetooth turned on but will only search and find nothing. The words 'Now Discoverable' appear under the search panel.

    for the devices to find each other via Bluetooth you would need to turn on the iPhones cellular hotspot and then let them search for each other. As far as I have found this Bluetooth connection is only for connecting the iPad to internet via iPhones data plan.
    To transfer photos you could setup a new photo stream and put the photos you want transferred in it. When it syncs to the iPad you can save directly to the camera roll and delete the photo stream. You may also be able to delete the photos old photos and re-add them to photo stream so it looks like they are new to the iPad.

  • Sonnet Encore Zif G4 Installed but will not boot.

    I am back and feel like the frustrated enator. I called tech support at sonnet and got the upgrade installed but B&W will not boot.
    I checked Sonnet tech page and I have no PCI cards installed and the hard drive that was attached out. However I can not get the power plug that was attached to it off could this be the problem. If so how does one pull it off?
    I also read some place may have been a post at site the some 256 ram may not be compatable with up-grade. I have 4 sticks of pc 133 non ecc in the B&W. Problem?
    I replaced them with 4 sticks of 64 ram pc 100 but still would not boot. Old ram that is untested.<

    After doing the firmware upgrade on the G3 some memory that worked before the upgrade will either not work or will not be fully seen. I had a couple of 128M sticks in my g3 that only showed up as 64M after the firmware upgrade, and one 256 pc133 that did not work at all.
    I seems you are trying to do three things at once: firmware upgrade, cpu upgrade, and memory upgrade. Doing all at once without confirming the success of each install makes troubleshoting your problem difficult.
    Go back to ONE.
    - take out the G4 upgrade
    - put the original G3 cpu
    - remove all but one stick of memory
    - boot into OS9 with the one stick
    -if no-boot then remove that stick, try another...
    - confirm that the G4 firmware patch has been properly installed (do it again)
    (even if you can not disconnect the power supply line from the PCI card thats fine as long as the card is not in the slot)
    -after booting with one stick, reboot and add ONE stick of memory , confirm memory in System Profile. Continue untill you have all your memory confirmed and working in OS9
    -once you have all of your installed memory working in OS9 boot into OSX, confirm the memory in System Profiler.
    -if no boot in OSX remove all but one stick, try that.
    -if one stick works, take it out and set it aside, try another, test each individually.
    -install all the working sticks you have
    -recheck that all the memory appears in System Profiler
    -Now reinstall the G4 upgrade with just one confirmed working memory stick in.
    -If that works put in one stick at a time and reboot, checking for the memory in System profiler each time.
    If this works you should have a happy mac. If not you will be able to report back with exactly where problem is.
    I know this is a lot of rebooting but IF you have a bad memory stick it is the only way to find it, and you have to ensure that all the memory is osx compatible before trying to install a cpu upgrade.

  • Mid-2009 MacBook Pro sees internal SATA hard drive, but will not boot from or format

    I inherited a Mid-2009 MacBook Pro (15-inch, 2.53 GHz model) with a very strange issue.
    It first presented itself as not being able to boot from the internal SATA hard drive that came with the computer. Nothing I tried could get it to boot, so I assumed the file system was corrupted beyond repair and booted from a CD to try to format the drive. Disk Utility on the CD would not format the drive, giving me strange error messages like "Unable to write to the last block of the device".
    At this point I figured the drive itself must be toast, so I pulled it out and put another known-good SATA hard drive in, booted from CD, and attempted to format. Again, same error messages and an unsuccesful format.
    So I had the bright idea of formatting one of the drives in an external enclosure and then putting it in the MBP to see if OS X would even install. No dice. Get a cryptic error message before installation even begins.
    So I installed OS X on the drive in the external enclosure and put it in the MBP, and it attempts to boot, but never goes anywhere.
    So to sum up, the symptoms I'm seeing:
    MacBook Pro CAN see internal SATA hard drives.
    MacBook Pro WILL NOT boot from any internal SATA hard drive and cannot format or install OS X to any internal SATA hard drive.
    MacBook Pro WILL boot from any CD or external device and seems to work properly otherwise.
    At this point I'm thinking it's one of two things: the hard drive ribbon cable or the SATA controller on the logic board.
    Since the MacBook Pro seems to work completely fine other than this one issue, and will boot properly from both external devices and the CD (also a SATA device), I'm thinking and hoping that it's just the hard drive ribbon cable. From my searches online, I've heard that this batch of MacBook Pros is known to have issues with the hard drive ribbon cable, but it seems in most cases this manifests itself by the Mac not being able to see a drive at all.
    I've done quite a bit of troubleshooting to get to this point, but right now I'm just looking for any feedback at all. Specifically I'd love to know a way I can easily test to see whether it's the logic board or the cable.

    UPDATE: An interesting development!
    I just tried a third known-good SATA hard drive, one which I believe supports SATA I only (but I'm not sure), and unlike the other drives that the Mac sees but cannot properly interact with, the Mac can't even see this one when I put it inside.
    Frustrating as this may be, I believe I'm actually getting closer to a solution since my symptoms now appear to be closely aligned with people having SATA ribbon cable issues.
    Onward!

  • Mac Pro Processor heating and will not boot

    Hi All
    I have a 2009 Mac Pro with dual processors, this has been a great system until recently it started to shut itself down after around 20 minutes of use, I tracked this to a processsor getting too hot and shutting down.  I air dusted the unit and replaced increased the fan speeds.  Now the mac pro will not boot.  As soon as I insert the power the motherboard flashes red and will not power up the system.  Is there something I can do myself?  Can I clear the mac bios?  Any thoughts or advice would be appreaciated.
    Cheers

    thanks Hatter, I appreciate your advice.
    The system is running 10.6.2, or was running.
    I tried the SMC reset:
    SMC Reset using "unplug, hold power for 5, release, plug in
    SMC Reset using "unplug, hold power button, plug in, release
    No change either way.
    What happens is, watching with the case open, when I plug the power cord in and two red lights flash on the motherboard "CPU A" and CPU B". And nothing happens from there, no fans, nothing.
    I wil try to remove the heatsink if I can find the right tool.
    Do you have any other thoughts?

  • Hard drive detected but will not boot Windows Vista or recovery disk

    Hi,
    I have a very similar issue with a HP Pavillion a6355.uk, the hard drive kept crshing windows and then it finally just kept getting pass the HP boot menu options, and then all I get is the DOS "@press ctrl+alt+del to restart".
    The hard drive is detected and passes all the tests, after pressing F9, going into the F10 options. F11 does not do anything, so cannot recover windows/the system.
    I have tried changing the SATA connections on the motherboard, no difference. I tried the recovery boot disk I created when it was working and it will not boot with the old or new hard drive I bought to replace it (same size and compatable).
    I cannot find where to partition the new hard drive or format the c: on the old one (it had D: for the recovery, but as it won't boot, cannot access this).
    I have also tried the HP website to dowload the drivers for the new one, but the page does not load up to show any drivers or Windows to download.
    http://support.hp.com/gb-en/product/HP-Pavilion-a6300-Desktop-PC-series/3644673/model/3671505/driver...
    The next page just keeps looping or not proceeding when I put in details.
    I can’t find anywhere to get hold of my copy of windows vista for this PC or get a disk to re-install on a new drive or fix the old detected drive, can someone please help!!

    Just what size HD and is the drive Sata II or Sata III?
    Vista 32bit .iso    You must have a valid installation key, which should be on the COA sticker on the computer, to activate the installation once it completes.  ImageBurn to create the .iso disk.   Driver page Vista (not 64 bit)
