Refornat Gone Bad.

[Hendricks433]

I just reformated my Desktop and everything was fine. I went to reformat my Laptop this morning and Now my screen doesnt work. Its lit up but just black. Im using a version of Win XP Pro I downloaded... would this cause problems since Im not using the Disc HP gave me? Is it like my driver is gone for my laptop LCD screen? idk what to do. Im in class right now but when I get back I want to hook it up to an external monitor. would this maybe work?
