Vertical green an yellow lines that a appear on slow motion on on top each other covering the entire screen. I tried to restart screen from button and the screen reamin lit. I stoped PC. Screen remain lit, so i pluggen power out of it. After restart PC everything was going back no normal. Anyone knows what could that event was about?
on desktop it could be bad video ram or the lcd panel having issues. if the pc does it again try another monitor to see if the error stays on the pc or the monitor. if it on the pc. turn it off check that the video card seated and the gpu fan not dust bound. on older gpu if it not the video ram it may be old thermal paste and it dried out and the gpu having hard time staying cool.
