Randomly in a mission my screen will go black, I lose audio and my monitor comes up with no signal. Have to reset my computer. It was happening ever couple of days or so and today it happened every time I tried to do a mission. I tried a bunch of stuff, fiddling with settings, changing to windowed and disabling multi thread rendering, updating drivers, verifying cache. After I verified cache it seemed to fix it, but it happened again just now. This problem only happens in Warframe, I just started playing again, never used to happen before.
