Screen flickering, desktop scrambling
I don't know exactly how to describe it, but a few minutes ago my desktop began scrambling and flickering, and there were black lines everywhere. It didn't stop until I restarted, which I couldn't do with my cursor because everything on screen kept moving around and was obscured by the flickering black lines. I thought it might have been a cord not connecting properly or something, so I checked everything going to my monitor, including my HDMI switcher, and all seemed fine.
Does anyone know what this could be?
