XPS 1730 game panel

Hello all,

I have a Dell XPS M1730 running windows xp pro. When I first got the system the gaming panel on the top right rocer of the laptop used to work, I reformated and never bothered to installed the drivers. Now that I've installed the drivers, the back light on gaming panel stays is on but there is nothing that get written on the screen, ie clock, performance monitor... When I push the button on the right side of the screen, all I get are white lines that go through for a sec then disappears.. I've tried to install the old drivers, the newest from logitech but still does the same thing. Would anyone have any ideas on  how to fix it?
