this doesn't happen every time, but often enough, and only since 10.3.5:
i get this black screen (when waking from overnight sleep) telling me in several different languages to restart from the power button. when i do, everything is fine
i've repaired permissions and SMART is verified
the only other thing i've done is use the new SystemOptimizerX which runs cron scripts, prebindings, empties caches ect. (i do this manually, not set for "overnight")
please tell me it's not my logic board (again)
