I am running multiple gaming desktops in my house, and it seems as though one of them is causing the internet to disconnect. We have 150 mbps internet, which typically runs at around 178 mbps (using speedtest.net), but as soon as I turn on my computer, our MS on games skyrockets, and we begin to frequently lose connection all together. I will be gone for 2 weeks at a time to work, and my wife has ZERO issues, but as soon as I am back home using my desktop, the internet issues begin. So far, I have run a Malware scan, and thorough virus scan (using Mcafee) and nothing has flagged at all. I NEED HELP!
Question One computer in my house is causing the internet to crash ?

if the issue is not happening when your wife is using it and only when you are its something you are definitely doing something on the computer causing it
So we each have individual computers, she has her own. So she isn't using my computer ever. But when she uses hers while I'm away, everything runs perfectly fine. It's only when we are both on our computers at the same time that the issues arise.
Home gateways (router) only support a limited number of connections, typically 100 to 200. If you run something that opens a LOT of network connections, like P2P programs, then it can lock up the gateway. The gateway has to keep a table to translate between the public IP and port to the private IP and port on your computer.
I can't imagine it would be the router not supporting the connections. Its just my wife and I playing World of Warcraft together, which shouldn't be an issue, as I have been with upwards of 10 people all playing WoW or LoL on one house router with zero issues. And I can't imagine a cable connection issue either, because the internet works perfectly fine as long as both computers aren't on at the same time. As soon as I use mine, the internet begins to disconnect.
*UPDATE*
Just turned on my Alienware laptop, plugged in for internet with the same cable as the one I use with my desktop, and zero issues. Wife and I both playing WoW, no MS issues, and no disconnects. So I think it's safe to say it is 100% something to do with my desktop computer itself.

Maybe you have a duplicate ip address. Make sure your PC is not using a static ip or that it somehow got the same address. In particular you want to make sure it is not using the same ip as the router.
If that looks ok look at the resource manager and see what process is sending data into the network. The network utilization should be huge if it is using up your connection.

think you may try;
1. Change Ethernet cable between your desk and router (if no spare) swap with your wifes PC
if the problem happens is when her pc is on its the cable replace it if not then see 2
2 . change port your pc is connected (again you can swap with your wifes connection on router) and see if problem moves with the swap, then its a router problem, if the problem remains it could be a bad driver or a bad network card (possible)
2a. look at the router logs to see if it is report something suspicious on your Ip address..
Just looking at my computer and my wife's computer, it seems like we both have the same Public IP address, I'm not sure if this could cause the issue? We both went to google.com and typed in "What is my IP" and our numbers are both the same. Is this just the router's IP or is our computer's IP?
I suggest checking the ethernet is set to automatic IP. This is under network connections->ethernet->properties->Internet Protocol Version 4 -> properties. All computers in your house will use the same public IP. Privately on the LAN (192.168.1.xxxx) they should all have different IPs.
The other possibility is that you have malware. My son had this once and it would do spam mailing using his computer. Or it could be using your PC for a DOS attack. You might open a command window and run netstat to see what is going on connection wise. You shouldn't have internet connections just sitting there with no browser or game running.

So I closed my browser and had no games or programs open, i ran the Netstat cmd and a bunch of line showed up, Im not sure what is normal for not having any active programs open, but there was definitely more than a few lines that came up.
*UPDATE*
I installed my fancy wireless adapter that I bought for my desktop, and it seems to be running things, both computers on and running, and both my wife and I are having speedtest results that match our internet service and then some, so Im guessing that it something to do with my network adapter on my Motherboard? This is an issue I have to replace the board for, or do I just have to swap something out?

jt get a network adaptor,. plug it in computer and enjoy, you need to add a new one I guess as your test show seemingly the on board one is causing the issue.

the best solution would be to get an internal ethernet card that will go into one of the PCI or PCI-E slots but if you are not comfortable opening up your computer you may be able to get away with an ethernet adapter that plugs into one of your USB ports
