Just started this recwently

 

6 years old 1.8 gig PPC. it starts but I suddenly lose sync to the monitor...it goes black...I've gotten a message once that OSX needs a restart...power is on but it just goes dead.I end up restarting and sometimes it works for hours, once it would not start at all for 1 start up..very strange.

I wonder if I can reinstall OSX without losing my stuff? my dvd does not work so i cannot burn dvd's...hasn't in years so I cannot back up...unless i get a usb drive.

 

Thanks...any suggestions ( other than a new MAC ..cannot afford it right now)

 

OSX 10.4.11, 1.8 G5

not good...

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

    Unless you elect "erase and install", reinstalling OS X does not erase your data.

     

    You will have a challenge without a working optical drive, but if its read capability is operational that's all you need to reinstall OS X.

     

    This may not fix your problem.

    Is the restart message you are getting in multiple languages? If so, you are having a kernel panic, usually caused by hardware.

     

    You can't reinstall the OS X system without a disc drive.

     

    If you get an external hard drive for backup, get an Firewire connected one. A Firewire connected external HD will be bootable, whereas a USB HD will not.

     

    Do you currently have another internal HD that you use for backup?

    I do get problems w/ my network too..it says 'The application settings have been changed by another program..." when I try to use it...I have to click to unlock, then it gets stuck in the spinning beachball, so I force quit and re open it at which time...it works.

     

    I remember that hideous mess.

     

    Simple fix: System Preferences > Security. Check the box for "Require password to unlock each secure system preference".

     

    I believe that wording is correct, but it is at least approximate. I am not at my Tiger machine at the moment.
