HT1752 Liquid On Top of PowerMac G4 Tower, Won't Boot

Liquid got onto the top of my PowerMac G4 tower. Now it powers up but won't boot. Has only the logic board been fried, or could there be even more damage? Any chance of recovering files from the hard-drive?

Impossible to tell what is damaged, but pull the Hard Drive & try something like this...

  • G4 PowerMac mirrored drives won't boot after software update

    This IS NOT about my PB but a PowerMac tower, G4, mirrored drive....running 10.5 (I think).
    After some month of neglect, did software update yesterday.... 7 programs including a security update, iTurnes, QT, and I'm not sure what else.
    Now it won't boot.
    I have a Disk Warrior CD, but I can't get the SuperDrive door open to try to boot from it.
    Help GREATLY appreciated.
    Thanks,

    Updating
    Certain steps appear to minimize the risk of an update producing problems.
    Number one is to make sure you have a bootable clone backup of your computer in case you do need to back out of it again. This is the only guaranteed way of not having to worry about the results of an update.
    Some like to boot from their installer discs or an external backup and verify (and if necessary repair) their internal drives as well as drive permissions. This is done with Disk Utility. You can verify a drive while booted from the same drive but sometimes this produces spurious errors. Repairing a drive (if necessary) has to be done while booted from another disk. Permissions repair can, and is probably best, done when booted from your internal drive.

    [Safe Boot takes longer than normal startup|http://docs.info.apple.com/article.html?artnum=107394]
    I like to download the update onto my computer and install it from there rather than let Software Update do it. I know a few people who had problems with doing the update via software updater found a manual install to work.
    Repair permissions again afterward.
    It helps to only install one update at a time and to run the computer for a while to make sure it is behaving well.
    The more cautious even like to unplug third party peripherals (see [comment by BDaqua|http://discussions.apple.com/message.jspa?messageID=9040746#9040746]).
    Almost all of the above steps (except backup) have been questioned as to necessity because probably many people have done successful updates without doing them. I say they can't hurt, they can very likely do good (especially if your computer isn't regularly maintained), so why not do them to be safe.

  • G5 Tower won't boot from other hard drives

    I have recently purchased a used G5 tower and cannot get it to boot from a second internal drive nor from external Firewire Drive - all running system 10.5.8. My G5's primary boot is a Western Digital Serial ATA on Bus A. On Bus B is a Samsung Serial ATA drive, and attached via FireWire is a Western Digital 1TB Mybook (with 3 partitions - one with system 10.5.8). When I go to System Prefs and choose Start-up disk, the Samsung on Bus B *does not appear* (although it shows up on my desktop). My FireWire WD shows as a Start-up drive, but when selected as my startup, and I reboot, the machine starts from the WD on Bus A again.
    I've been with Macs ever since the 80's and served as system and network manager for all our units--installing, upgrading, and troubleshooting dozens of Macs in our unit. I'm now retired and this is the first time that I've encounter a problem like this. I've tried switching buses and jumpers but nothing seems to work.

  • Powermac G5 desktop won't boot

    2004 Powermac G5 desktop: when I push start button sometimes only get fan sound other times if I push start button again I get chime and other times it goes to apple logo on gray screen but no spinning wheel. how can I boot up?

    BDAqua: thank you so much for staying with this. after 11 tries it got past the chime on the 12th try and holding down the CMD+s keys at bootup yielded a black screen with the following:

  • PowerMac DP G4 Won't Boot With All RAM Sticks Installed

    A few weeks ago, my 800 MHz dual-processor G4 started having frequent kernel panics. I tried all sorts of things, including changing the PRAM battery, resetting the firmware, and resetting the PMU. Then, one day, it would only power up but not boot, so I took it in for repairs.
    The shop I took it to determined that the logic board was malfunctioning and replaced it. The computer no longer has any kernel panics.
    The machine was designed for three 500 MB RAM sticks, which is what it had ever since I bought it over five years ago. Now, apparently, it won't boot with the last one installed, though it will with two. The shop replaced the new logic board and and even swapped RAM, but the problem still persists. Neither the power supply nor the hard drive appear to be malfunctioning.
    Does anyone have any ideas what's going on? Any ideas or advice would be greatly appreciated.
    Thank you.
    G4 800 MHz Dual Processor   Mac OS X (10.4.9)  

    squeakmaster, welcome to Apple Discussions.
    Have you tried the following with one 512MB RAM stick:
    1. Palce it in the first RAM slot. Does the Mac boot?
    2. If so, remove the stick & place it in the second RAM slot. Does it boot?
    3. If so, remove the stick & place it in the third RAM slot. Does it boot?
    The results of this test should reveal (1) if the stick boots in one or more RAM slots, the RAM is good and (2) if it fails to boot in a RAM slot, there is a problem with that slot.
    Do this with each of the tree RAM sticks & post back the results.
    When the logic board was replaced, was the firmware updated to be compliant with OS X. (Note - The firmware is installed on a chip on the logic board.) Check your Mac's firmware (Boot ROM version) version. Mac OS X: Available firmware updates
    http://docs.info.apple.com/article.html?artnum=86117 If an update is required, the update must be installed (using OS 9) BEFORE you install OS X.

  • G5 tower won't boot; fans ramp up until I shut down

    I'm running a Dual 1.8 GhZ PowerPC G5, with 1.5 gig of RAM. I recently replaced the power supply, as the one that came with the machine died.
    I left the machine running last night, and this morning I found the fans ramped up as high as they could go, and the screen telling me that one of the external devices had been disconnected improperly. (This had happened once or twice while I was using the computer before I went to bed. Couldn't figure out what the problem was.) I shut down the machine by holding down the power button. When I turned it back on again, it wouldn't boot. I get the startup chime, and the main HD spins up, but the screen remains blank (the light on the display still works the way it should).
    I was somehow able to get the machine to start from my backup drive once, so I verified and repaired the main drive. It checked out fine. I tried another restart, and the machine wouldn't boot again. It has since refused to boot, getting no farther than the startup chime.
    I've tried pressing the power management button. I've tried booting from the Leopard disks, and I've tried zapping the PRAM. However, it appears that the keyboard isn't having any effect, as the last two didn't work either.
    Anybody have any thoughts? I've removed and reseated one of the RAM cards, but haven't had a chance to try the rest yet.
    I can't afford a new machine right now, so I'll try pretty much anything to get it to work again. Thanks!

    UPDATE: I removed the Belkin PCI card I had installed in the machine, and it started up with no problems. So, it would appear the card is the problem. It's been working fine for months. Is it possible that it just up and died for no reason?
    This is the card I had in the machine:

  • G5 tower won't boot beyond chime, fan is possessed?

    Hi, have been having problems with my Dual 2.5 GHz PowerPC G5. Fan has been running loud and fast, and on last restart, whirred like crazy w/no reboot. Shut off by pressing power button on front of unit and waited a few minutes. Now when I try to turn on, I get a chime and brief noise as if trying to start but then nothing but blank screen (if I leave on, the fan gets loud after a few minutes). Also tried unplugging power cord for a few minutes then restarting, but that hasnt worked. Cannot find my OS X disks (augh!), so what now? Would appreciate any help.. thanks .
    P.S. Just bought a new super-de-dupery mac pro and was getting ready to backup my G5 before transferring files. How does it know...?

    I had the same trouble 2 years ago.... Turned out to be a bad RAM chip. I had enough RAM to pull two bad chips. I have been running on 3GB since then. The computer ran fine until this AM. I cant start it but the fan doesnt wind up. Good luck.
    Bad RAM may sometimes cause the power LED to flash in a particular pattern on power up, though this usually happens when you don't get the boot tone (or as we like to call it, the chime). Something to note when you attempt to power up.
    See http://support.apple.com/kb/HT1547 for some information, some of which applies to G5s.

  • Help!!!! trying to install leopard on a powermac g5 tower

    ok im new here and i would like to get some kind of help. i have a powermac g5 tower that is been giving me alot of problems. i currently have 10.4.11 and trying to upgrade to leopard. but every time i do the install process it quits on me and tells me the source media is bad try to install again or restart it. i did that already and still no go. so i contacted the apple people and they first tell me that my opitical drive was bad so i go ahead and replace it. still gives me the error message. ok so i call again they tell me ok that my hd is bad i need to replace it. ok so i being the dummy and listening to them go buy a hd and try to install it once again nope still gives me the error message so i call them again and they tell me ok that i need mac os tiger and the leopard should just install fine. nope i bought tiger for cheap on ebay and nothing no luck i cant get to work i keep on getting the message that the source media is bad and i need a new disk . so im really confused as to why i cant get leopard to install in to my g5.
    p.s. i do have another copy of leopard because the mac people taught that my disk was bad but i know for a fact that the one that they sent me is not bad also.
    p.s.s .
    please help me to try to fix this problem thanks

    sorry about the late answer. but i do not have the tiger cd like the one in the picture mine is gray and it says on the dvd for g3g4g5 install dvd. also the leopard cd has the big x on the dvd. i called once again the apple people to see if they can help me now they tell me that my ram is bad. so first they told me my optical drive was bad. then my hard drive, then my video card was not right. then i needed mac os tiger to install leopard. so now i need ram. also all the plugs for the optical drive are installed right and the hard drive also installed right. and i tell them the specs and they tell me they are more then fine for leopard. so now im going to purchase some new ram to see what happens. also is it true that mac os leopard needs original apple ram to work. i keep on reading about that

  • Operating system on a PowerMac G5 tower

    I have a later 2005 PowerMac G5 tower with the intel. I took it to the shop for a previous problem and the tech asked me if I wanted to Upgrade to Snow Leopard. I need to know if "Snow Leopard" is compatible with a Intel PowerMac G5. OR What the Latest OSx is compatible with it?

    japamac has you covered on the model question.
    If it is truly a G5 then Leopard (not Snow Leopard - oh why did Apple have to give them similar names?) is the highest system. If the technician was offering to upgrade to Leopard I would seriously think about going for it. Tiger is no longer supported and Leopard will be the last OS that machine will run. Then too, it is hard to find a copy of Leopard and if the shop has a copy they will sell you at Apple's retail price I'd go for it. The main hesitation would be if you still use OS9 generation software since Leopard does not have Classic.

  • OS 9 Powermac G3 Won't boot from CD

    My OS 9 CD won't boot on my B&W G3. I want to install OS 9 and then install OS 10.3 on top of that but I can't get it to boot from the OS9 CD. Any ideas?
    Message was edited by: plop1234

    The Option key at startup should bring up Startup Manager where you can select from available startup disks. If you have the Mac OS 9 disk in the drive, it should be one of the options. Your Panther system should be another option.
    If you are using a non-Apple keyboard, I'm not sure it will work, but the Option key is the Alt key on a Windows keyboard. If you were using the C key at startup to boot the optical drive, maybe that's why it did not work, because it was not an Apple keyboard.
    A dead PRAM battery can cause startup problems. If it was very weak, resetting PRAM may have drained it the rest of the way. It looks like this

    If you have a voltmeter, you can check your battery to see of you get 3.6v.

  • Powermac G5 won't boot - but safe mode works fine!!!

    [The computer described below is a Powermac G5 dual core 2.7gHz, purchased in late 2005, running OS X 10.4.11]
    Here's an odd thing... a few months back, my powermac stopped booting. It wasn't a power supply issue. I would get the white screen with the apple to come up, but when it was time for the blue screen with the user logins, the screen would go black.
    I tried swapping out all the RAM, and nothing worked. Was able to get safe mode to work, once, and then never again. Finally I broke down and took my baby to Tekserve.
    Tekserve took a MONTH to get it back to me, and they claimed it was a bad RAM set. This sounded really odd to me, since I thought I had correctly tested several sticks of RAM, and even no RAM, without any success. But I'm not one of the experts, so, hey. My computer was running again and that's all I cared about.
    Well, now, about 3 weeks later, my computer will not boot. It started with the loud fans. Now I'm not having any fan noise, but it still won't boot. Here's how I've troubleshot it so far:
    - The computer boots FINE in safe mode. I verified the disc in safe mode, and everything checks out. Everything also checks out using fsdk -fy in single user mode. So no disc problem, apparently.
    - When I reset the PRAM using crtlopt+pr after the chime, the screen resolution changes from 1200x1024 to 800x600. After the white screen, I do get the blue screen, but WITHOUT any user login, and the mouse cursor does not show up.
    - When I reset the NVRAM using open firmware (reset-nvram, set-defaults, reset-all), I'm back to my normal problem of white screen followed by black nothingness (and emotional despair).
    Tonight I'm going to try swapping out the RAM again, but if that doesn't work, what's next? I don't know where I put the original Hardware Test DVD that came with the powermac... is there a program I can buy to see if this is my logic board, without bringing the powermac back into tekserve? I live in NYC and have no car; bringing this heavy item into Manhattan is a real issue for me!!!
    Anyways, any and all info is greatly appreciated. I really hope I'm overlooking something obvious. Natch, neither Apple nor Tekserve want to give me any advice without me shelling over more of my hard-earned cash. And this all went down 3 months after applecare expired... sigh...

    Very interesting... they're telling me (at Tekserve) that this problem is caused by bad sectors in my SECONDARY drive. Doesn't make any sense to me at all, but that's what they're saying... pretty sure the RAM and video card are fine. I tried resetting NVRAM and PRAM, and that did nothing... safe mode works fine, as I mentioned... even got it running in normal mode for about 30 seconds one time.
    It's the shop now, so we'll see, when I get the computer back, what the real problem was. It makes me flabbergasted that bad sectors in my secondary drive could have any effect whatsoever on boot!

  • Powermac G4 (OS 10.4.11) won't boot past grey apple

    1- My PowerMac G4 (running OS 10.4.11) won't boot past the grey screen with the apple.  Any suggestions?

    I found somewhere else how to hold down the mouse on starting, which opened the tray.  I was able to startup with the disk, holding down the C and get to the Disk Utility window.  Tried repairing the disk, but got this message:
    Fist Aid failed:
    Disk Utility stopped verifying "Macintosh HD" because the following error was encountered:
    The underlying task reported failure on exit. <OK>
    and in the info window it says,
    "Verifying volume "Macintosh HD"
    Checking HFS Plus volume.
    Catalog file entry not found for extent
    The volume needs to be repaired.
    Volume check failed.
    Error: The underlying task reported failure on exit (-9972)
    1 volume checked
    0 HFS volumes verified
    1 volume failed verification
    Sounds pretty ominous!  Of course, the recommendation is that I backup everything , but how can I if I can't get to the desktop to back it up?  (It hasn't had a lot of use for sometime, but is available as a film scanning station, and so that I can access scanned images on my iMac.  I doubt that there is a whole lot on the drive that isn't backed up, but I would prefer to back it up for sure!)
    Thank you again.

    Reinstall Lion, Mountain Lion, or Mavericks without erasing 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
    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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
    Reinstall Lion, Mountain Lion, or Mavericks
    OS X Mavericks- Reinstall OS X
    OS X Mountain Lion- Reinstall OS X
    OS X Lion- Reinstall Mac OS X
         Note: You will need an active Internet connection. I suggest using Ethernet

  • Powermac G5 - ocz Agility 4 ssd won't boot

    G5 Power mac - ssd storage upgrade - ssd drive won't boot when blessed.
    1. Installed 2 new drives into old G5. Upper slot - 2TB sata hdd, Lower slot - 256GB ssd OCZ Agility 4.
    2. Formatted both drives as Mac OS extended (Journalled).
    3. 2TB drive partitioned into a 'Data' partition. (~90%) + a 'Backup Boot' partition (~10%)
    4. Installed 10.5 onto the ssd.(Named 'System 10.5')
    5. Restarted system as part of install.
    6. System booted back to installed disc.
    7. Went into 'Startup disc'. Selected ssd with 10.5.
    8. Restarted system. System still boots to install disc.
    7. Installed 10.5 onto 'Backup Boot' partition on 2TB drive.
    8. System restarts OK.
    9. From 2TB hard drive system. set ssd to startup disc.
    10. System restarts to 2TB hdd.
    11. Restart system, hold down option, ssd appears. select as boot disc.
    12. System boots to ssd, and the welcome animation starts to complete the install.
    13. Download the 10.5.8 combo update and install.
    14. System doesn't reboot to ssd, but 2tb hdd.
    Aware the booting requires a system folder (drive) to be 'blessed', I started poking around the web to verify if the ssd was set for the startup.
    Running the command : 'bless -info' returned the following:
    finderinfo[0]:    215 => Blessed System Folder is /Volumes/System 10.5/System/Library/CoreServices
    finderinfo[1]: 239774 => Blessed System File is /Volumes/System 10.5/System/Library/CoreServices/boot.efi
    finderinfo[2]:      0 => Open-folder linked list empty
    finderinfo[3]:      0 => No OS 9 + X blessed 9 folder
    finderinfo[4]:      0 => Unused field unset
    finderinfo[5]:    215 => OS X blessed folder is /Volumes/System 10.5/System/Library/CoreServices
    64-bit VSDB volume id:  0x9FC3EB20743384E4
    So the system was 'blessed'. Tried the 'option key' method at startup but still not getting the ssd to appear as a valid boot option.
    Looked on the OCZ website which has a Mac OS boot utility for flashing the firmware on the ssd drive BUT the drive is already on the current firmware : 1.5.2
    Running out of ideas, short of re-formatting and re-installing the system onto the ssd.
    Any ideas of other fixes?
    (Feedback really appreciated).
    Screengrabs of sata drive profiles attached. (hopefully)
    Thanks in advance.
    Ps. Ssd drive appears on desktop reads / writes / etc when booting into the hdd.

    THANKS BDAqua FIXED !!
    I hadn't installed the ssd into the top slot due to not being able to easily fit the apple rounded hd screws into the mounting tray - hence just letting it sit in the lower position. By working out the holes of the OCZ tray with some other hd screws, I was able to fit the apple hd screws then slot into the top (upper) position & the 2tb drive in the lower position.
    Now all working as expected. Thanks again.
    Matt.

  • Powermac G5 won't boot past apple logo screen

    I'm trying to repair a Powermac G5 (dual 2.0, the first model I believe, with a new Radeon 9800 graphics card) that won't boot and I'm having some problems that I can't seem to diagnose.
    The machine will boot to the openfirmware prompt or target disc mode and will show the 'OS not found' icon if left to boot from the HD (which has been wiped). If I try to boot from either the included restore disc or a retail 10.4 DVD I've tried it will show the boot screen with the Apple logo on it but no spinning status indicator underneath. It just freezes on that screen. Once it showed the status indicator but it just continued to spin for about 30 mins, at which point I gave up. Same issue if I try to boot the hardware test (except it freezes on the hardware test loading icon rather than the Apple icon). The superdrive appears to work as it is accessible in target disc mode.
    I've reset the SMU and reset the PRAM via the keyboard shortcut. The one thing that leads me to think it's a firmware fault is that when I run the 'reset-nvram' command it gives an OK, but when I then run 'reset-all' it freezes rather than rebooting. Any ideas anyone?

    I am having the same problem with my Power Mac G5. I have had a problem with the machine for the last few months, I just turned it off waiting for Leopard (started using a laptop for projects).
    I got Leopard, tried to boot off the DVD, I only get to the grey Apple logo and then after a few minutes the fans kick on high and I just have to shut the machine down.
    I didn't want to lose any thing off my hard drive so I went and bought a new one and installed it, when that failed to install to, I bought a new optical drive. It still won't boot off the optical drive. I can go into the firmware and choose which drive to boot from (I choose the optical).
    My configuration at this point is a new DVD drive, new unformatted hard drive, I have used a laptop to try to install from using the G5 in target mode, using the laptop in target mode to use as an optical drive. All of these steps have failed.
    I have 4 gig of RAM, Pioneer 112D DVD, Maxtor 250 Gig HD, I have reset the SMU, I have the NVidia card (can't remember which model).
    Any ideas where else to look for a solution?
