I have been using this keyboard for quite a while and it was fine until it started double typing some keys. Now everytime i click most keys just once it will type it 2-3 times. I have tried cleaning the keyboard fully (taking off the keycaps) and i have also tried updating firmware, reinstalling synapse, closing all razer apps, and using it wired. I also plug dongle/cable into motherboard usb port directly. Please help.
