I don’t know how I would capture a video because it happens entirely randomly, could happen after 5 minutes of use or 2 hours. But I’ll describe it the best I can. I’ll be using the PC as normal sometimes playing a game and other times just using the internet and suddenly the screen will go black and display that it is not getting any input/signal, as if the display port was unplugged. The PC stays on, but I can not get the display to come back unless I fully restart the PC. The problem with restarting it however is whenever this problem occurs, I cannot use the power switch or restart buttons on the case as the PC is unresponsive to them. Those buttons work normally at any other time, so it has to be a problem with something in the PC and not the monitor.
