Long story shortened a bit. I have a 2-yr old MBP 3,1 (the first Santa Rosa line) which has recently hit a slew of problems (bad fan, new display, new hdd, new logic board) over the last 3 months. I thought all was fixed then yesterday it suddenly dies, starts kernel panicking on boot, and I can't even boot from an installer disk. I took it in to the Genius Bar today and the guy puts a stick of their RAM in and it seems to work +/- ok. He won't do any more until I put the original RAM back in (upgraded to 4 gigs a year ago). I take the laptop home, and it magically starts working. I grab a couple backups and it starts kernel panicking again so I grab my original RAM and put it in. Now it's still kernel panicking and I'm effectively completely locked out of my MacBook Pro (the RAM worked fine in my wife's 3-year-old MacBook which takes memory of the same specs). Any ideas or am I just screwed? I'm scheduled to take it back in tomorrow, but at this point I don't know if I can afford more repair time (been without the laptop for probably 3 weeks out the last 3 months and I am a PhD student... integral to my work).
