Strange thing is I found the solution by accident….I was pressing the ‘s’’ key trying to get it to work and it displayed a snapshot on screen, to cut a long story short a program game capture by elgato had the ‘s’ key assigned to snapshot, so wouldn’t work if the program wasn’t running…..so just removed the shortcut…..so suggestion is to try I save mode, use task manager to close all running tasks…..se if it works then…..or try booting into troubleshooting mode, hold Shift while rebooting ( I think that’s how ) & Open a cmd prompt and try typing ‘p’ in there……good luck
