Three beeps when trying to install snow leopard
Hello there,
I bought a MBP early 2011 on ebay but it has a problem, it gets stuck on a white screen with the apple logo and a spinning wheel. so i decided to buy a new hdd and os x snow leopard. when i try to intall snow leopars onto my computer, the MBP beeps 3 times, i did a research and looks like its a ram problem, but i try my rams on my pc and they did work. so i would like to know how can i fix this problem and could it be caused by the worng os x, i have os x 10.6.3 ( bought it from apple). do you guys think i need a newer os x. thank you in andvance.
