Once you install Winodows. Just head over to the manufacturers website for your motherboard. Download all the drivers, chipset, audio, network and anything else that's extra and required.
If you have any PCI cards in, go get the drivers for them from their manufacturers site, e.g. graphics card, sound card, tv card, wifi card etc etc.
If you first need to install a network driver to get online to get these, either use the network driver off of the cd that came with the mobo and then update by following above or use another pc and transfer it over using a flash drive or something similar.
I would then install the chipset drivers first, followed by the rest in any order.
Then I would do Windows updates. Once all that's done I would go and check the device manager to check for the dreaded yellow exclamation mark. This would indicate your computer doesn't recognise a device... most likely you have missed the driver for it.
With regards to the BIOS settings. If you aren't overclocking it's quite simple. Either keep it on Auto which actually isn't all that bad, or manually set the ram voltages and timings as according to the piece of paper you got with it or the product page where you bought it.
Change your first boot device to your hard disk or SSD if you're fancy. Disable anything you don't need for e.g. booting from lan. This always take a few seconds during post for nothing, so unless you use it... just disable it. Everything else is optional. Just go through the settings, 90% are self explanitory and if you don't know what the setting does, chances are you don't need to know
Hope that's helped and if I've made any errors or someone disagrees. Then.... you're wrong!!!! haha. Feel free to correct any mistakes as you see fit.
