I've had a dell inspiron  15 7000 series (7559) for about a month and so far I have loved it.  Yesterday when I went to shut it down, it didn't shut down like it normally does.  A unexpected window popped up, but the display shut off before I could read it.

Today I've been having trouble with video playback.  It's not just on one application or site.  Netflix.  YouTube.  Facebook.  Even the free Microsoft Solitaire Program that came with the computer. Approximately every 10 seconds there is a jump in the playback or program.  It's almost as if another application is interrupting the current processes.  I've also tried to go into the Dell Help and Support Application, which I've had no problem previously accessing.  And for some reason its saying it can't connect.  Any help would be appreciated.
