Q: Following update, no display on G5

Following 10.5.8 update, G5 has no display (blue screen).  Have performed safe mode, repair, Reset SMU/PRAM.  I can view the desktop if I connect to iMac.  Is it safe to assume the video card needs to be replaced?

    Sounds lie it, but does Video show if you bootfrom the Install Disc holding the c key down?

    Come to think of it, I had video when booting from install disc while holding c key down.  I went to Disk Utility from Installer menu, chose First Aid > Mac OSX Volume > Repair.  The result was Volume Header needs minor repair/1HFS Volume repaired.  Checked Permissions and all priviledges were verified or repaired. Upon reboot, blue screen.  Upon several reboots, blue screen.....?

    You say G5, but there is no info regarding what is in the G5.

    What graphics card are we talking?

     

    Blue screen is often a software issue, not necessarily a hardware issue.

     

    If you can boot to Safe mode, remove any User Login items.

    Thank you.  The PowerMac G5 has a NVIDIA GeForce 5200 Graphics Card.  When I boot to Safe Mode, unable to view desktop, blue screen.  I also searched for application enhancer software but not installed.  The blue screen occurred during a software update to 10.5.8.

    Do you have the original software install discs with the AHT on them?

    If so, run that.

     

    The machine wouldn't happen to show video when booted to an OS install disc would it (not then, now)?

    If so, reinstall of the OS may be in order.

     

    A corrupt update file could be the culprit.

    Might download the OS X, 10.5.8 Combo Update to your other machine. Then, via your network, reinstall the update.

    This would likely patch any failed kexts.

    Thank you. I was hoping to avoid the reinstall but will go that route. Appreciate the help.
