Hi:
HP no longer supports that motherboard since it is more than 10 years old.
You will have to find the drivers from the hardware manufacturer's websites, or from other HP business PC's that have drivers for similar hardware with the same specs.

Since you do not mention the model of the PC, what version of Windows you are running, etc., that is the best I can do to help you at this point.
