    is this the update or bad hardware? osx crashes
    as soon as i rebooted from the 10.5.5 update

    the screen flickered with anomalies like this

    i thought nothing of it well it just happened again 3 times in a row

    one time it went into a kernel panic and as i rebooted while filling out the kernel panic report it did it again

    this time it wouldn't boot it just gave beeps not sure how many its either 2 or 3

    so what's the diagnosis guys?

    Specs:
    27" 5K iMac, 3.3GHz, 256GB Flash Storge, 16GB memory and OS X.11.3.
    Three beeps defective memory or defective memory slots.

    Try reseating the modules very firmly.

    If no joy remove one pair of whatever memory you have and boot again.

    Next try booting from install DVD and run Repair Disk and then Apple Hardware Test, which also checks memory.

    Still no luck beginning to look like a logic board, so maybe off to local Mac dealer.
