Why does my default web browser open in bursts when playing any video game?

So, when I'm playing games, my default web browser, no matter what one it is, will constantly open. Depending on the game, it could be every 5 minutes or every 10 minutes, and it usually happens in bursts. I have a radeon R7 240 graphics card with the most recent update, and it has been happening for a while. It isn't a hotkey because if i left to get something for an hour and came back, there would be at least 30 tabs of my web browser open, and It's not a virus as I've used 5 different programs to search for it, and also reformatted my pc, so it's still happening. It's getting to the point where I'm ready to scrap my PC.
