Ok.. I have a Toshiba Satellite L305 s5875, and I did the Windows updates and now when I turn it on there is a flashing cursor in the top-left corner for a minute or so and then the Toshiba logo screen comes up and it just sits there. It will not allow me to enter setup or anything. I have been doing some research and I am guessing one option would be to reset the BIOS. If anyone has any other suggestions I would be grateful...
