Can't Install Leopard On mac G5

[bradley1023]

Hello all

I was given an old imac G5 and it still had the previous owners old files on it and tiger installed. So i booted it up with a Leopard CD and successfully wiped the hard drive without any trouble. But have had no luck trying to install the OS, at any random time it will just freeze up entirely and the fans will kick in high speed. looking in the log as it downloads i have noticed it creates many thousands of the same error

"unable to find db handle 2" its also said "unable to find db handle 1" many times. I am more then happy to supply more information just not sure what you will need, thanks in advance

What kind of Mac OS X 10.5 Leopard DVD is it? Retail or Restore or Drop-in DVD?

The DVD is retail and i know it works, as i have used it to reinstall the OS on my other G5 in the last couple of months.

Pull the drive out, stick it in that other G5 and install the OS on there then stick it back in this reluctant G5.

Thats a plausible idea and it will probably work but the other G5 is my day to day computer that i use, the very one i am writing this on . So i am not sure i am ready to put a Hard drive in it that could possibly be troublesome in my good Mac until i get some more answers, especially when i have read some other similar problems where the hard drive was the culprit.

I have since found out that it does not only freeze while attempting to install the OS, sometimes it will freeze and put the fans into hyper-speed before its even made the boot up chime. It also froze and fans sped up while trying to remove the partially installed OS from the Hard Drive. I have the impression this is some sought of safety mechanism where it turns the fans up so it doesn't overheat, but where could the problem lie?

I would first try replacing the 3.6 volt lithium battery located on the logic board. As these go dead, they can cause all sorts of boot up problems. You should also reset the PMU following these instructions from Apple.

I'd also remove and reseat the RAM just to be sure the contacts are clean.

Then try a reinstall of Leopard.
