Crippled Internet when one computer plays online games on a 1-5 computer network

So I have an in home network, 5 computers connect to our okayish cable connection, through a switch and a router. Two to three of these computers play MMOs or any online game. The problem is this. My computer (and it has been doing this for years!) sometimes goes into Anti-Me mode, wherein when I connect to a game the connection becomes crippled for everyone. Streamed music fails, streamed video fails and pages well they just won't load. Long pings attempts cause low pings but multiple timeouts. This only happens when my computer does this. The other 4 never cause this issue.

At one point I troubleshot the entire network. Connected through to the modem alone. But that changed nothing. Without or without the network this one computer does this. Another piece of information this is the 4th upgrade of this computer. Motherboard, CPU, RAM, and Video card is different from its 3 other iterations. The problem has existed in all 4 upgrade attempts.

I've scanned, hunted, and even glared hard at this computer. But I can't find the source. The problem also isn't consistent, though has certainly changed this year. Before it would happen at a certain time, now its more random than ever. My ISP cannot seem to tell me what is causing it, and there really doesn't seem to be a similar issue in the whole of the internet (But I suck at the search thing).

Don't suppose anyone can tell me what it might be or how I might find it? Its driving me nuts!

It could be that some application on your computer is using up bandwidth or flooding the network. When you experience this problem, use Task Manager / Resource Monitor to examine network usage. You may find that a running process is using up a majority of your available bandwidth.
