Best way to find out and install the drivers you need

So i finally finished building my rig and know im going to need drivers, logan and linus have said never use the driver disc that has came with the product. So my question is where do i go to find out what drivers i need and install them, kinda like how  my alienware laptop uses the dell site to find all the drivers you need and can download them directly from there.

Ok so if you have an Nvidia graphics card then geforce experience will keep you up to date, you can otherwise find drivers to download at nvidia.com/drivers. Chipset updates, bios updates and utilities can be found at your motherboard manufacturer's website. If you have ASUS go to www.asus.com if you have MSI go to www.msi.com. the way to navigate is often a products tab -> motherboards -> find your exact motherboard model once you've found it and clicked it for details, there should be drivers & utilities somewhere to be found.
