I cant see anything but a black screen

Solution
Well if the computer is turning on, but only the screen isn't. You need to determine if it is the screen or the graphics card.

Try turning the laptop off, plug in an external monitor, turn the monitor on, then turn on the laptop. If the screen shows an image, it is the laptops screen that needs repairing or replacing.

However, if the external display is also black (yet the computer is on) then your graphics card may be having problems and/or need replacing.
