Will a new copy of Win7 have drivers for your something something laptop?
Kinda hard for us to tell.
Like robustus64 is saying. The HP support website will have drives for HP, Dell will have drivers for Dell, etc.
And you could try what Microsoft suggests:Update a driver for hardware that isn't working properly
watch the Demo Video
They mention the automatic and manual methods for updating drivers.
(but not all options will work till you get the internet connection working).
