Everytime I turn on my Sony Vaio laptop, a black screen pops up with a flashing underscore in the top left of the screen. I've tried restarting it, there is nothing connected to the USB ports, and I don't have the setup disc. Is there anything I can do to fix the computer myself? Please be as descriptive as possible
The black screen will set there forever to infinity and beyond
