Sounds Nasty can you boot back in with Safe mode if so you might need do a restore if possible. When you start the computer does it look like it is going you know hdd lights and such if it looks like it is going try to plug a monitor in just in case the laptop screen died the lines are either the Screen or the graphics I believe. I have been wrong before

. I hope it is not too serious and I hope these suggestions help. If I think of anything else I will post them.
