Xbox 360 controller help, Camera/character spinning.

Hello, I play on PC and use a controller and all of a sudden when my controller is plugged in my camera and character spin/walk around without my input. This never happened before a few days ago. I've only got the one controller plugged in, and as soon as I unplug it the spinning stops. I thought it was my controller, as it' pretty old and busted up, but I bought a new one and even the new one is spinning and everything. I tried it in other games (I don't have many to be fair) and it doesn't happen in them (Overwatch for example).

If anyone knows of a way to fix this I would really appreciate it, thanks.

Ok, sorry for an almost immediate closing to the topic, but I solved my issue. Even though my analog sensitivity has always been at 0, all I did was bump it up a bit and it fixed itself. Idk the logic behind it, but I won't complain.
