Can you plug an external monitor into the laptop?  Most have a video connection.  Maybe that will help if your video had failed.

Subject: [PCBUILD] Update to won't boot

My dell laptop inspiron crashed. I get no screen now. But when I did get a screen it said N4_disp , the device driver got stuck in an infinite loop which usually indicated a problem in the device itself or the device driver prograMMING the hardware incorrectly. Check Dell for driver updates. I disconnected the printer which was the only thing attached. It is going thru a wireless. Without a screen I cannot proceed with tests or do a restore. Should I reinstall the os? It is Windows xp Media sp3.
