    I started to have problems with random crashes of Mail and some other programs, ran Disc Repair (it found some problems and repaired them twice over a two week period).

    Started getting a series of three beeps, silence, three beeps, etc. on restart.

    Ran Apple Hardware Diagnostic and it found a problem. Error code was:

    4MEM/4/40000000: 389151d8

    I don't know what that means, but I have two 2gb memory sticks in this machine. Does the code indicate RAM failure?

    I'd be grateful for any advice or information.

    1,2, or 3 beeps at start up indicate a RAM problem. Remove one of the sticks of RAM and recheck. If no different, remove the second stick and replace the first. Check again.
