I am fairly new to building computers, and I am starting out with the mother board. What are the parts I need to build a motherboard? Also, how can you reprogram your BIOS?

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
If you're new to it you can't design your own PC's motherboard. Despite their low cost motherboards are pretty advanced electronics. A common EDA tool like Eagle is not fit for the job, where you need to take transmission lines, matched impedances and matched trace lengths into account.
A typical PC motherboard may have more than 10 layers. Having made one will cost you more than a PC from the shop around the corner. So you want to make it right first time. So you want simulation tools. Cost: several 10k, up to 100k dollars.
You can't prototype a > 100 MHz PC motherboard on a breadboard, it simply won't work. Besides, all the required components are SMD, many BGA.
If you are planning of integrating at circuital component level than I can't help.Its something where you really need infrastructure and precision to integrate such things.
If your computer is some new model from previous 2-3 year release, then believe me you are going to do a dangerous job.Its not suggested to flash your bios, because your manufacturer writes many routine specific to your computer assembly.
