Q: I cannot start my g5 mac os x 10.4.11, startup light flashes six times

I cannot start my Powermac g5, with OS X 10.4.11; startup light (which you can see under DVDrom drive) flashes six times; I have 4 GB RAM, I have tried to change the  memory bars in different position or remove 1 couple but no change; I have also tried to install the hard drive system in another mac and from there I could well open the drive and see all  the files; then I put the drive back on my machine but computer does not start.

Can anyone help ?

PowerMac, Mac OS X (10.4.11)

    Hello,

     

    1 beep = no RAM installed

    2 beeps = incompatible RAM types

    3 beeps = no good banks

    4 beeps = no good boot images in the boot ROM (and/or bad sys config block)

    5 beeps = processor is not usable

     

    In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.

     

    Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.
