Thank you Sir, it's back working again, with no screen saver.

Thank's also to others who responded, much apprecaited.

I'll be back later, now I can see the error messages that were hidden 
behind the saver when something burped, only becoming visible as the 
otherwise stalled machine shutdown on one short press of the power key..   
I just need to wait now for the trouble to manifest itself again.

Cheers All
