Windows 10, Screen Freezing

[WolfpackAW]

After my PC has sat idle for a while, my screen freezes (both the laptop display and the main display). The laptop display goes dark with only a mouse cursor visible. The main display has the last image on the screen but no input is accepted. The only solution is to disconnect the USB docking station and then reboot the laptop. I have attached the diagnostic information as requested. Any help would be very welcome.

Thank you.
