    A weird thing happened after I installed the latest 10.5.6 update downloaded from apple.com. The update I downloaded is the combo 668.7MB dmg.

    After installation, I restarted as promted.

    The MP restarted, then System Profiler showed only 12GB out of 16GB of RAM installed (I have 8x 2GB, but Riser B's DIMM 1 & 2 showed "empty""). Next the sys froze when attempting to open Activity Monitor.

    I restarted OSX, now the screen of death at Apple logo

    I turned MP off, took each RAM Dimm out and physically reinstalled. Started the MPagain, same thing.

    Repeated RAM physical reinstall as before.

    Restarted and everything works --16GB of RAM. FYI, my RAM is from OWC.

    Any idea what went wrong? Does it sound like a software/RAM/MP issue to you? :confused:

    I think you could of avoid removing the memory, if only you knew how to reset the SMC and the PRAM
