Notice this problem couple weeks ago, when i play some heavy games or use high res above 900P screen would blinking to black screen for couple of time indefinetly blink stop after i close the program/game or play low GPU intensive game. blink can be stopped when i lower the resolution even thou sometimes they coming back when the're high action in screen like explosion. sometimes blinking happen in main menu where there're transtition in screen like when you select choices in main menu.sometimes blinking will be acompanied with "sound" like when you trying put audio jack on speaker.
