Recently, I built my own computer and did some stress test to overclock it. However, my PC always failed the Luxmark 3.1 test (both the scene file validation and image validation). I wonder if my monitor or graphic cards have problems, since sometimes when I play a video in my computer, it turns green when it ends. Besides, the screen sometimes flashes with vertical line when I move my mouse to wake it up from sleep and the vertical line immediately disappear.
