So I was working with the not quite latest update to the free version of Avast, when after a quick scan it offered to do a boot scan. I figured why not, it had been a while since I had restarted my machine anyway. Short version: Upon restarting I can see my lights come on and hear the beep associated with startup. My screen remains blank and is no longer transmitting anything at all. I have switched HDMI cables, switched monitors, inserted a boot disc... Everything short of kicking it. This computer is fairly new and has never even crashed before this. I have restarted it many times without issue, the only variable that has changed is the Avast boot scan.
