Q: My powermac G4 won't boot

When I try to boot it lets out 3 loud beeps and the monitor light and power light flash at intervals, Also sometimes it powers on with no boot indication (beep, Apple logo) but the power indicaters light up.

    Hi, sounds like a RAM problem, but have you blown the dust out lately?

     

    Can you count the beeps or flashes?

     

    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.
