My MacBook Pro won't start- 3bleeps
Hey. My MacBook is a 15" pro late 2008 non unibody, I haven't replaced the ram but the MacBook will no longer start up, I just get 3 bleeps, I have tried swapping the ram and the screen just stays blank, no backlight, nothing, when I put them back in the original position I get 3 bleeps. Does any one have any tips or advice that I could try, cheers.
MacBook Pro, Mac OS X (10.7)
