Don't know what is causing it but recently my pc has sometimes just started acting crazy and unresponsive, when this happens, it's completely unusable, and I have to turn off with the physical power button.
Here is a video showing the problem, it contains no audio but I am madly clicking with most actions being unresponsive: View: https://imgur.com/VcToJzt
