    Hi Guys, Please help. I have a PPC G4, all of a sudden I switched on and the machine beeps. First 1 beep then 3 beeps, the screen stays black, it keeps doing this continually. I really don’t know what to do? Can anybody please advise me as I need to somehow get the machine to boot up. Thanks:confused:

    Zap PRAM & NVRAM. Google "resetting pram and NVRam."

    Check your ram sticks one by one to see if it's a bad stick of ram.
