i have the same problem as you please tell me if you fixed it thank you

Hi I have fixed as follow reinstall windows new formatting disks to last update with windows mediatool 1807 when you are in fresh windows with intel display create recovery point so if anything goes wrong you don't need to do the whole thing again. instal nvidia drivers it should not crash. disable nvidia display in driver manager and restart. when in desktop enable again nvidia display and you will see u have updated nvidia drivers with no problems. now what im doing is everytime I shutdown computer I disable nvidia display so intel display is on when I boot again computer after shutting it down. it works perfectly I have been doing it for 2 weeks and no problem always do recovery points I have mine max 10gb and keep doing it just do be safe. only thing is don't shutdown computer with nvidia display in device manager enabled always disable it when u finish with computer but in any case recovery points will keep u from having to reinstall. make sure u don't do recovery points with nvidia display driver enabled or it will crash. I tried to update nvidia display driver from device manager and computer crashed deleting recovery points so be weary of doing that. im using my computer like that with an asus mg279q fressync gsync enabled and it works flawlessly. your welcome if u ever know how to bypass epsa test at boot up let me know bregrds
