Yesterday when I shut off computer it did an automatic update. During the update I unplug the ethernet cable. Everything was fine. Today I woke up and turn my computer on. Its shows my motherboards company logo and then All I see is a black screen with a white line in the top left corner. When I boot it and tap f10 nothing happens. Please help me .
