I have a Dell Latitude laptop and updated from Windows 7 to Windows 10. After the update I have the next problem. I start the laptop and see the logon screen, then I logon within my account. After logging in I subsequently see my desktop and a black screen. The screen actually is flashing. Sometimes I manage to open Microsoft Edge and can browse. But when I close Edge I end with a black screen with only the mouse cursor visible. If I don't open Edge, but wait, after a a couple of minutes the flashing stops ans I end with the same black screen. Anyone a clue how to solve this?
