Hello. I just purchased 2 Centon 2GB RAM sticks for my early 2008 15-inch 2.4 GHz Macbook Pro. It is the DDR2-667 SO-DIMM, 200-pin. I have Windows 7 on my MBP via Bootcamp. My MBP had 2 1GB Samsung RAM. When I replaced them with the new RAM my MBP worked fine at first. After running a few games I got a BSOD. After attempting to reseat the new RAM my computer isn't even recognizing the new RAM.(I get those beeps when I start the MBP up) I put back the original RAM and my MBP works fine. Does anyone know what I should do?
