    ok, i installed 4gb (2x2)of ram in my alum macbook pro 2,4ghz 15" and in the 1 first time i didn't took off the battery but it went well and booted ok, after that i turned off the computer and the next time keeped making noises.

    i tried put the old ram and it's everything ok, i tried both ram slots and memoryes and the 1rs booted ok alone but the second didn't, what is happening, it's the second ram damaged or have you another explanation?
