M60 - Scroll and back button problems

Hello,



I bought a Corsair vengeance M60 about a year ago, and roughly 3 months ago, I started to have some issues with my scroll wheel as it keeps getting worse.



To explain a little more, when I scroll up on a webpage, a game, or a software for example, it randomly scrolls down and up. However there are no problems when I scroll down, but it's getting very frustrating.









I also have a problem with the "back" button that only works sometimes.



I tried to install, reinstall, ... the software and firmware, but it didn't solve the problem.









Thanks, Serfion.
