So I have a bit of a problem where my screen flashes, I instantly thought it was display drivers so I uninstalled them only to worsen the problem, the computer restarted with a black screen which later turned into a desktop screen with no icons and a flashing screen (can't click anything or even load up the start menu with the windows key). I put it into safe mode but it does the same thing. Nothing works except task manager and i can't run task from it or it will exit out, system restore doesn't fix the issue either. Computer is a lenovo k450 i5-4440 8gb ram 1tb hdd with an evga gtx 760. If you need any more info let me know.
