I suggest that you either RMA your mouse and get a replacement or if you don't trust Razer anymore, go with some other brand, e.g Corsair or Logitech.
Razer products, while popular for some reason (have no idea why) are plagued with software and hardware issues. I still wonder why people still buy Razer products when it's known well that their products have issues. I guess too much marketing is behind it with catchy looks.
