    I just got my macbook back from the Apple Store (The Power Board and the Top casing (keyboard, mouse) had to be replaced).

    When I just turned it on, however, I hear this screeching sound, and when I install something, the fan goes berserk, and the screeching sound gets higher in pitch!

    What should I do? This never happened before? Is it a hardware problem or is it the software, "Fan Control" from Lobotomo that I installed?

    PLease help!

    take it back, apple obviously messed up. If you're nice they might just give you a whole new machine.
