Hi

 

Had problems w/ my g5 1.8 OSX 10.4.11 for a while now-- i started getting shutdowns, no restart sometimes for days then..just starts. Fan full on sometimes...til I shut down. I get the multi-language error message sometimes and other times it just goes out even after hours of use.

I cannot reinstall OSX, the dvd drive has died too. I know...great. I bought a 500 gb drive w firewire capabilities = but the adapter cable for firewire is like 40.00... ridiculous. I'm on disability.

 

so after much mucking about like doing a bunch of things I found here (  ..PRAM, NVRAM, and OSX utilities...) during one set of maintenance I realized that half my ram is not working. I pulled the second slots out ( I have 2 x 516 and 2 x 128 {I believe} sticks...) and then swapped with the first slots ram ...both sets of ram seem to work fine in the first slots but neither works in the second dimm slots ( i am aware of the dimm pattern going center - out). Is it possible the logic board or a controller or other hardware device has failed? With all 4 sticks working it doesn't make sense that the 2nd dimm slots would fail but I guess anything is possible?

 

I would really like to get this mac working..I am trying to get a loan for a new imac when the haswell models come out--speculation and rumors say this month...but I need a second mac for my music mixdowns. Ideas...suggestions appreciated...thanks ( new imacs, mini's and cash also appreciated  :-)

G5 1.8, Mac OS X (10.3.9), 1.5 gig RAM

    If you have Installer Disc which came with your G5, try Apple Hardware Test if it's a hardware problem.

    Or chech RAM with system Profile(Apple menu ->> About this Mac -->  More Info)

    Great work, sounds like a Video card problem now, though becase of the temp think can't rule out the lead-free solder issue.

     

    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...

     

    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive

     

    Reboot, test again.

     

    If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed.

     

    Check the System Preferences>Other Row, for 3rd party Pref Panes.

     

    Also look in these if they exist, some are invisible...

     

    /private/var/run/StartupItems

     

    /Library/StartupItems

     

    /System/Library/StartupItems

     

    /System/Library/LaunchDaemons

     

    /Library/LaunchDaemons

    Does Safe Mode work OK?

     

    .should I go on??? Intel??

    If you want more headaches, I highly recommend it!

    "Try Disk Utility

     

    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.

    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)

    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*

    3. Click the First Aid tab.

    4. Select your Mac OS X volume.

    5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."

    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.

     

    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

     

    Tough without the Install disc, but some things to try...

     

    Does it boot to Single User Mode, CMD+s keys at bootup, if so try...

     

    /sbin/fsck -fy

     

    Repeat until it shows no errors fixed.

     

    (Space between fsck AND -fy imoprtant).

     

    Resolve startup issues and perform disk maintenance with Disk Utility and fsck...

    Just recently I ran into a problem when I tried to Verify my hard disk and when it tried to verify the catalog, it responded "Invalid sibling link." Repair Disk didn't work. I searched the web and Apple's site, and couldn't find anything useful except to buy DiskWarrior or reformat the drive. Knowing that OS X is built on Unix gave me a few clues on how to proceed. The solution is pretty simple:

    1. Boot off the OS X CD (reboot, hold C while booting).
    2. The installer will load up, go to Utilities in the menu and run Terminal.
    3. Type df and look for the drive that has your Mac system mounted---you'll have to unmount this. On my MacBook Pro, it was /dev/disk0s2.
    4. Type umount /dev/disk0s2, replacing disk0s2 with whatever disk your OS lives on.
    5. Type fsck_hfs -r /dev/disk0s2. If you umounted the wrong thing, it will complain that you can't repair a mounted drive. Go back and umount the right thing and repeat this step.

    Just for fun, you might want to run another fsck_hfs on your disk (use the -f option because your drive is probably journaled). Hope this helps someone so they don't buy a program that's going to do pretty much what we did with fsck_hfs, and so they don't waste time searching for an answer to no avail. By the way, TechTool Deluxe (3.1.1) didn't find the Catalog problem for some reason (you'll have this on a CD if you have AppleCare), which is why I resorted to fsck.
