lots of very odd stuff...many safe mode starts-malewarbytes, ccleaner one or two vram starts....goofy stuff on beach ball- windows slow to open ..deleted cache got rid of extensions blah blah--does not like my hd discs I have plugged in via a 3.0 hub and other inconsistent operational anomalies...biggest deal is takes over two minutes to boot up from a complete shutdown...so is it operator problem? sierra? both or full moon?--Thank You
