What you have to do is reduce your hardware acceleration according to dell. go to Start> control panel> displays(in classic view)> settings> advanced> trouble shooting then just lower the slider a notch or two.

Dell Inspiron 9400 laptop display problem


First power the system on using Fn+Power and see if the diags run and you have video. If you have video in the diagnostics, then I'd suspect the video card as the failure point.
Also connect an external monitor and press Fn + F8 to activate the VGA port If you get video on an external monitor, I'd suspect the LCD as the failure point.
