Sometimes, during work, watching YouTube, the image becomes solid white, and the computer hangs tightly. After a forced restart, the computer does not boot, and the cooler of the video card runs at full speed. But as soon as it is completely de-energized (turn off the power switch of the power supply and hold down the power button), it works normally again. This is only seen in Manjaro Linux KDE. Plasma 5.20.4. The drivers are open.
