incredible crash

Hello,
I work with UE4 since one year and with the same machine.
My problem start when I install Windows 10. Even if i come back to windows 8.1 my problem stay the same.
I have no problem with the other programs like Revit, Blender etc…
My problem : with UE4, it starts normally and I can work with no problem if I don’t go on my 2nd screen.
When I go on the 2nd screen the computer crashes without having any message.

Thank you for response.
