I have just gotten an Hp pavilion dv9000. When I try to boot it all the board lights come up, the dvd drive tries to load but the screen stays black and there is no noise from the fan either. I don't have its hard drive so I don't know if its putting power or not. Also I'm in Australia but there was no Australia link so I just used usa. Please help I wan't to get this working. Corey.

I'd hook it to an external monitor and see if that works. You might have a bad LCD or inverter. If the external doesn't work, it might be a bad video card. Some of the 9000 series had recalls. I'd look into that also through HPs site (you'll need you model/serial number, google HP recall)
Oh, and the fan may not come on until the CPU warms up (passive cooling).
