I have a 6 year old Huawei that briefly shows a black screen with coding being processed - usually when I start a program, sometimes when I go to a website (but not all programs or not all websites). I know.....notebooks are cheap, but I would like to take this opportunity to learn more about the hardware in notebooks - maybe crack one open and play around. I am very comfortable building a desktop - have never bought an assembled desktop - but never taken a notebook apart. It is still the same install of Win 10, an i5 with 16gb of ram and 500 gb memory disk (maybe mr.2). Does anyone know what is going on?
