    If you tried to install a Copermine PIII (800MHz) into a laptop that had a
    Katmai PIII (600MHz) and vice versa, you may well have damaged both CPUs.

    Sounds like you weren't grounded when you handled them, and they got zapped
    with electrostatic charges.
    And/or, do they have any little DIN switches that got accidentally changed?
    And/or, are you sure they are plugged in correctly, with no bent pins, and
    fully seated?
    And, how do you know that a PC boots if there's no sound and nothing on the
    screen?
    Incidentally, what's the CPU? #pins? socket? etc
