What does the message "invalid memory access" mean?

文本:

I was given this powerbook G4 model A1138, which doesn't start up beyond the apple screen. When I tried to use the apple hardware test disk, I received the message, "invalid memory access at srr0:0002c2d4   srr1:00003030". Then there is info on the machine, Apple PowerBook5,8 4.9.6f0 boot rom build on 10/05/05. Welcome to open Firmware, system time and date is 01/01/1904 00:01:20. There is then the choice to type "mac-boot" or "shut down". Typing "mac-boot" will get me back to the apple screen again and no farther, "shut down" works just fine. Also the little timer under the apple will stop after a few minutes and the optical drive will too and then the screen appears frozen/stuck.

I have tried to use a (new) OS X 10.4 install disk and only get the same results. However when holding down the option key at start up, I get a blue screen with an icon of the hard drive and the install disk and both icons have a small x on them, what does that mean? When using the hardware test disk, only the hard drive icon has the x.

Where do I start looking for the problem for this mac? Hard drive?
