I have been having this super annoying problem with my windows 8.1 laptop, and I can't remember when it started but it has gotten worse. there is this black box that pops up on the the screen every 2 min. (NOT LYING I HAVE SERIOUSLY TIMED IT) Anyway the only thing I have seen so far was it says SYSTEM 32 in the green bar on top. Now where this really bothers me is when I'm in full screen mode, watching a movie ,playing a game and so on it just minimizes to the taskbar and I have to open it from there, otherwise if I'm in windowed mode this "black box" still pops up but doesn't minimize the program.
Usually I would try and figure this out myself but I have gotten nowhere, and the internet has LITERALLY got nothing and the frustration is killing me, so please I need some ADVISE.
