    Z390Dark, 9900K.

    During POST, reaches D5, starts over, never enters UEFI.

    Bad CPU?

    Anyone?

    D5 = Bootblock code is copied from ROM to lower system memory and control is given to it. BIOS now executes out of RAM.

    memory or memory controller is dead

    Must have been memory controller. New CPU and all is well once again.
