Was playing Fallout4 with no problems.

All of the sudden when I looked down my sight everything turned black and I could only see my HUD.

Reloading past saves does the same thing. I can only see my ammo, crosshairs, health, Pipboy, settings, etc.

Sometimes reloading a past save starts off in this black screen sometimes it starts off fine and turns black when i try to aim.

Has anyone run across this problem and how did you fix it?

** only happens when I use a gun with a scope apparently.
