Answer 1

Find out what the components (& brands) are & then go to the manufacturer's site to download the drivers.

This free utility may help you identify some of the hardware in your PC ... especially the mainboard.

Answer 2

First of all you must known what driver you need???
I think they are: Mainboard driver, soundcard driver, LAN card driver...
To known what the name of these you need some program to test: Sisoft, CPUID, Intel® Processor Frequency ID Utility (if your mainboard belong to Intel) ...
When you know what you need --> come to http://downloadfinder.com and search.
Good luck!
