Ok, so I built a new computer last weekend, and hooked it up with ethernet and the internet was really slow. I tried a different cord, and that didn't work either. When the computer is off, the speed goes back to normal for all the other devices (laptop, other desktop). Here's where it gets weird. If I unplug the ethernet from the new desktop and turn it on, the whole house experiences slow internet. Once the desktop turns off, internet goes back to normal. It apparently has nothing to do with the ethernet, but the computer itself! The new desktop sits right next to the router, but they are plugged into different wall outlets. What could possibly be causing this? Any and all help is appreciated!
Edit: Also, this computer is the only device hooked up via ethernet, in case that helps. All other devices have wireless.
