Hi, new member here. I just bought a used Mid 2009 MacBook Pro 15" and I need some help. The person I bought it from said that the RAM is bad from what the tech person he took it to said. When you press the power button, the fans turn on and you get the Apple chime but no display, you can insert and remove a CD though. I'm wondering if it is a display issue though. I can't test different RAM in it because my friend is being a tight a** and won't let me borrow his Pro to try out his RAM in and my RAM in his. Got any ideas?
