I just upgraded my Surface Pro 3 to Windows 10. I log in and as soon as the desktop loads, my screen flickers/flashes rhythmically and I am not able to do anything. The mouse cursor is fluid, but I can't get perform any tasks. I booted up in safe mode and there is no flickering issue at all and I have all functionality (well as much as safe mode allows). This makes me think that it has something to do with the current video drivers or something. I downloaded the latest drivers off of the Microsoft website on my desktop, moved them to a thumb drive, and dropped them on the desktop of the surface (in safe mode). I cannot run executables in safemode though, so I can't actually run the executable on my surface at all. It just sits there...and taunts me. I have read online that this was a common issue in testing and previous builds of windows 10, but it seemed to me that it was all fixed. I am looking for help from anyone that might be able to offer a suggestion.
