    I wonder if the hisses are distorted beeps?

     

    Does it restart fine once running?

     

    Older meanings...

     

    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.
