    I just purchased (2) 2GB PNY PC-5300 memory sticks for my black Macbook but when I install both 2GB stick my MacBook will not boot but when I install (1) 1GB and (1) 2GB it boots up fine with a total of 3GB listed in the About This Mac and it doesn't matter what combo I try with the sticks. The 3GB works but the 4GB does not. Any answers as to why would be great.

    Which model of the MacBook? More information on the specifications are needed.
