My Mac G5 is presenting me with the power LED flashing two times, a pause and repeats the two flashes. The information I could find states that the memory modules are not present but I have two 512MB modules installed.
I tried replacing the memory with known good memory with and had the same results. I've also replaced the 3.6V battery and the 600W power supply.
Nothing seems to work and my system still can not get past the memory check, no beeps, no gray screen, mo splash screen, nothing. However it will power-up with all the fans turning, and I can hear the hard disk drive movement.
How can I figure out why the memory will not initilize?
