well, we need some more information.
Is it brand name or did you build it?
If you built it:
What are the technical specs?
Particularly, did you install an ethernet card or does it have an integrated nic? what type is it(wireless/wired).
Same goes for display drivers.
If it's an on-board graphics card, then the drivers should come pre-installed when you install windows. If not, then you have to use the cd that came with the graphics card, or get the ethernet drivers working, and go to the manufacturers(of the graphics car)' website and download the updated drivers.
