If you are a complete novice to computer building, please ask for help before purchasing your parts. There are many things to consider in choosing each component; budget, usage, compatibility, power consumption to name a few. As I've said earlier, don't hesitate to make a thread in THIS section asking for a build. Even if you do not plan on buying from Newegg, which I recommend you do anyway, it can still be used as a great resource for browsing parts.
There are also some great resources out there for computer builders. One being Tom's Hardware, which often times creates builds based on different budget tiers. They also do benchmarks and product reviews. Check them out (I've listed a few others as well):
