I went into safe mode, couldn't locate the problem...then restored to an earlier date, that worked for awhile, then problem started all over.
Finally, located that it seems to be my comcast connection. I don't know if it is the comcast receiver [unplugged and reset it several times] that is giving me the problem or if it is a comcast overall thing.
The TV lost it's signal a couple of times in this same timeframe and the laptop lost it's connection, too. [although, at no time did the laptop have either that dreaded black or blue screen.]
Do you by chance have comcast, too?
No I dont have comcast
