Hello, i have a HP Notebook model 15-DY0017DS.. It is only 3 month old and only one week after purchasing.. It started glitches when i moved it or lifted it, by splitting the normal window and another window showing on the top corner ( only a small part) whilst the screen, cursor and keyboard remained function less until force restart.. Then it continued with irritating buzzing sounds.. Failure to turn on by displaying black screen (with white bleeping lines in a interval of like 2 sec) then recently when i lifted it, the whole screen flashed and displayed glitches like many colorfull boxes and lines or i may say a graffiti.. I've tried to downgrade from windows 11 pro to 10 Home but still it persists.. Help 😞
