I'm having black screen issue with my PC - when I lock it - all looks ok, turn off the monitors, leave for a few hours and then I turn them back on and it's just a pure black screen with no mouse cursor or chance to do anything. Also happens when I restart it, boot options bit loads up then nothing but black screen. If I restart three times in a row, my normal lock screen pops up and it's fine. Have virus scanned, malwarebytes etc, computer isn't, graphics drivers are all updated. Very confused, anybody have any ideas? Thanks in advance!
