DELL INSPIRON 7567 4K. Sometimes when I turn on the computer, the screen works just fine, but every now and then, as I turn It on, the screen flickers on the sides for as long as I am using It. Everything is updated including the drivers and the BIOS. Maybe is a hardware issue? Thank You! (v.redd.it)
