Intermittent Display Loss
I think I'm in the correct forum for this puzzle. My laptop display suddenly goes black and I hear a sound like when one inserts a flashdrive. Then the display quickly comes back up for several seconds before again going briefly black and finally returning, i.e. the blackouts occur in pairs. The second outage causes another sound like when one removes a flashdrive. After that everything goes along fine for another fifteen minutes or so before doing the trick all over again. This behavior seems to've developed out of nowhere. My brain's memory is vague, but there's a chance the last change I made before the black screens started might've been an Ethernet or WIFI driver re-installation, for what that's worth. Got any remedy ideas?
