Okay so real mystery here I have an SE/30 and the machine boots fine and works great. Power supply and analog board all seem fine. Thing is now after say 15 minutes of use the screen goes black and then sometimes it will try and pickup where it left off on the same screen but freeze, other times it will stay off completely while the machine runs. I'm using a BlueSCSI and the SE/30 is very clean. Any ideas, is the machine overheating or what's going on here? I've added a photo below of what all is going on, this was shortly after booting.
