Hi all, I just received a 12" Powerbook I bought off eBay. I was told that everything is fine with the computer, and the seller told me that he would be reinstalling the software. I just got the computer, and it won't boot. When I start up the computer, it doesn't get past the first screen and stalls with the following error: "You need to restart you computer. Hold down the Power button for several seconds or press the Restart button." From a quick Google, it seems that this is a kernel panic (I don't know...is it?) What do I do about it though? Any ideas?
