The 17" is an Intel and has an increasing level of vertical lines on the screen. Also lately it has started freezing for no reason. Have nothing attached but keyboard.
So decided to buy a second hand 20" Core Duo( it's actually older than the 17"). I tried Migration Ass. but for some reason it did not work with all files so I connected in Target mode. I believe this is not the way to do it.
I have a drive that I use for Time Machine but can't boot from that either.
There is an OS. X.4 stuck in the drive and won't come out. The 17" is running X.6.8 and I believe the 20" was the same.
Tried reseting PRAM
