Hi Guys, I got a Mac Classic for my bro at the Thrift Shop. I saw it on display and it was like $7 so I was like "why not" I tested it there and it seemed fine. I brought it home and it seemed fine. The next day it wouldn't work. Whenever I flick it on it stays Idle at a grey screen with tiny black horizontal stripes. It stays like this for hours. Yesterday, I turned it on and it worked (mind you this is like 2 months after I first got it) I ran Norton and SAM and they all came out fine. I turned it on this morning and it stayed at the screen again. Whats going on? How do I fix it.
