I noticed my external drives, even when Time Machine was off, active at night when computer was asleep. ??? Anyway, in the morning, the video had died again, screen was black and wouldn't wake up. Already has replacement logic drive so NVDIA video card problem was not solved. How to I get to the System Log to see what actually happened? No error message when I restarted.
