hello, i found an old clamshell ibook today. it started right up and all; seemed to work fine. well, now it wont boot at all. im by no means talented in this area, but i love to tinker around with stuff, i tried putting an airport extreme card into the wireless slot, and of course i dont think to shut the machine down to pull it back out. basically the screen distorted and froze. did the logic board get toasted? thanks in advance
