InfinityEu :
...to also note some people did say on the web that a possible solution to the freeze/hang was doing the key sequence win+ctrl+shift+b to apparently reset the video or something but that just completely froze the pc for me
That key combination just release and restarts graphics drivers (empty video buffer, resets, etc), but it also might do the same to the keyboard, mouse, sound chip, etc.
The computer might appear to be frozen, but it could take several minutes for drivers to load.
