Computer while running will ocassionally go to black screen and say 'boot device not found', I'm able to
correct the issue by powering down, waiting a few seconds than powering back up, computer will boot
back up as normal and work fine. This happens maybe once a week. My fear of course is it at some
point in time not coming back up. Is there any corrective action I should attempt now ? I have a hybird
static hard drive (ST500LM000-1EJ162)...Thanks..
