I had done a bit of research and I'm still a little confused. I went to use my macbook and the screen was purple with lines all over it, so I restarted it. When I restarted it, the screen was black and it was making beeping noises. It makes about 1 beeping noise every 5 seconds. I read that one beep means there is no ram installed. Is there any way to fix this without going to apple or am I just better off buying a new macbook? My macbook is 4 years old so I don't have applecare anymore.
