Hi everyone, I just bought a MacBook Pro from 2007 on eBay today. I tested it when I picked it up, it seemed to work fine. The seller didn't turn it off when he gave it to me but just closed it. Later I reopened it and for no more than five minutes I looked around on Finder. Suddenly it attempted to restart and then froze. I turned it off and never managed to turn it back on. At first it was just not reacting when I'd press the power knob. Then once suddenly it turned on while it was just lying there. Directly I had a kernel panic : grey screen with the apple in the middle, and white text on black underlining saying things like "panic (cpu caller 0x....)" and "Mac Os Version : Not yet set". Just that and then nothing. Turned it off. Now when I turn it on I hear the fan. Sometimes it seems to stop right away, sometimes it goes on but nothing displays on the screen anyway, sometimes the fan seems to go a bit out of control... What the hell is going on ? Is there something I can do or do I just return it right away ? Thanks in advance for your help! Antoine PS : I told the guy on the phone about the problem, he said that's weird he never had that, and advised me to take out the RAM and put it back in, which I did but it did not help. He did mention having changed the 1Gb RAM for a 2Gb one as the second slot is defect. Also the battery has to be replaced but right now it is fully loaded and I'm using the power cable of my wife's 2010 Macbook too.
