PowerMac G5 freezes right after startup

I am working with a Quad PowerMac G5, and it has been freezing every time I start the computer, often seconds after pressing the power button.

I have tried starting up the computer in Open Firmware mode (command option O and F) to reset the ram, but before I can start the sequence (reset-nvram...set-defaults...etc.) the computer freezes.

I have also tried to reset the PRAM, but the computer only resets again and then freezes.

Finally, I have tried to boot Tiger with the intention of running repair/disk permissions, but, once again, it freezes before I can start the process.

Any suggestions would be appreciated! Thank you

Try a safe boot. Cold boot holding down the shift key.

when you say freezeing, is it throwing a kernal panic message of does it just stop? Also do you have another mac from which you could boot this machine using fire wire target mode?

I would check the ram to ensure it is fully seated as that can be a cause of freezing.
Also unplug, reseat all the internal cables as I have seen this occur if a cable has loosened which cuases a slight change in the way the pc sees thevoltage thus causes a freeze.
