How to diagnose my hardware?

May sound very stupid but on my office system i need to install drivers of sound etc and all i know is that the motherboard is of MSI and i dont have the motherboard CD how do i go around this and find out the drivers which needs to be installed? any tips?

go to MSI and see if you can download

"live update" it will then scan your mother board, it can flash your BIOS, with Live BIOS, and test to see what drivers you have, when ever I do a fresh install on my PC I go install Live update download the latest drivers, burn them to my back up CD, and then install them on the fresh install.

MSI is Great for that feature
