I have a MP 1,1 that requires a restart after a few seconds. My son appears to have disconnected the monitor without turning the MP off first. Possible cause and effect? Or is it likely the logic board just gave up the ghost? No other recent changes, it's running 10.6.8. Or something else? Thoughts appreciated. It's a 2x2.66, 1 TB, 8 GB, 7300 graphics.
