I've had a very bizarre issue which I assume must be because of Cura because it has only ever happened when I've had Cura open (so far it has happened about 10 times in about 5 hours total of having Cura open. I didn't use Cura for two weeks and nothing happened. Today I used it again and experienced 3 crashes). Sometime, whether I'm currently working in Cura or just have it open in the background, my screens turn off and the computer becomes unresponsive. It doesn't even respond to the power off button anymore, I have to turn it off at the power supply and then boot again. It doesn't seem to be related to the load on the computer. Has anyone experienced something similar or has an idea what might be causing this?
