I recently just built my first gaming computer. Whenever the computer is on, even if it's just idle and not doing anything the Internet is terribly slow for everything else I have connected to the Internet. With my old computer this was never an issue. Is there some sort of setting in the bios or somewhere that I need to change? Also could you please explain this to me in very basic terms, as I know very little about Internet and networking.
