Hi, everyone. I hope you can help me.

 

I've just installed a new Hd in my iMac G5, formatted the hard drive, and now trying to install OS X (10.5.6) from the install cd. The installation goes well utill "about a minute" is left, and then the machine freezes. At the top left corner it says "SYS" in a small black square...

 

What can I do to fix this?

 

Hope you guys can help me!

Thanks!


iMac, G5

    Try rebooting the system, and see if it boots into Leopard.

    If it doesn't, try a full disk check, the disk may be faulty.

    Hi, edex67.

     

    The hd is brand new, and just formatted. Have run a disc check and it is ok. Rebooting does not work.

     

    Just tried to reinstall, and the machine locked down at 1 percent of verifying the install dvd. This is frustrating.

     

    Can it be the issue of condensators that I've read about elsewhere?

    By condensators do you mean capacitors?

    If so, it could be. The iMac G5s do have particularly bad capacitor issues (like the Dell Optiplexes of the era).

    Maybe dvd is a little bad. Look at dvd.  Any defects?

     

    I'd try a minimal install to work around bad spot on dvd.  Try to customize the  install & leave everything out.  You can add it in later with Pacifist.

     

    Try boot up install dvd.  Go into utilities.  Go into terminal.  If you know unix, play around. If not just let things sit.  See if machine stays up.

     

    some unix commands

     

    type command then press return

     

    id

    ls

    pwd

     

    if it crashes, you found out some thing bad.

    The dvd is good, and it has been verified by the computer before install.

    I can do some commands sometimes, but other times it crashes. It does not seem as if it is any particual software error that makes it crash, cause it crashes at such random times.

     

    @edex67

    Yes, I do. But I have done a visual check against images of bad capacitors, and they look alright.

    So you booted up the dvd.  click on utilities.  Got into the terminal.  Did some unix commands on the command line.

     

    Sure sounds like a logic board problem to me.  or some other hardware problem.

     

    I'd take the machine to an apple store & have them look at capacitors.  I read were they can be bad when not looking the part.  I've read where there is a solder problem with some parts that are heat related.

     

    does the machine stay powered on?  capacitor problems with powersupply too.
