I was using my computer normally with this ethernet cord for a long time. I got an xbox and decided to use the ethernet cord from my computer on it. I unplugged it and it worked fine on the xbox but when i went to plug it back in the computer it wont recognize it. When its plugged in it acts like nothing is plugged in. My motherboard is a gigabyte 970a-ds3p. Ive tried restarting the router ive tried using different ports on the router, nothing worked.
