First: Welcome to ComputerHope.
Second: That is not a netbook. It's a Tablet PC.
Third: Looks like your screen is bust.
When did this start? Any drops or whacks to the screen? Have you been poking hard with the stylus?
Also, how old is the laptop?
From the picture, I see you have a VGA cable plugged in. Are you using the laptop via an external monitor?
