I i recently had a problem with my laptop:
one day i turned on my laptop and the a kind of artifacts on the screen after some cleaning new thermal paste i found out that my gpu was overclock so i underclock it after that the screen went blue but before the underclock there was artifact but was possible to see colors i check my lcd cable but's ok my gpu its also ok so my question now is it possible that when i underclock my gpu i mess up like a color setting or stuff like that?
