Switch chatter

Hello,i'm new here.I'm here for ask a little help if u can.Last year in December i bought the Blackwidow Chroma TE v2(green switches) keyboard,after 3 weeks of normal use the nr "1"key started to chatter randomly.The keyboard is very clean,no dust or other pieces of food(chips,snacks,etc).I've tried to blow the switch with compresed air and nothing,i've uninstalled Synapse 3 the issue still here,trying different usb ports,plugged in another pc,laptop the problem persist.I've tried to install Synapse 2 and uninstall it too,cleaning registry directory,i reinstalled the OS(win 10 x64 Pro).I also try to reduce delay in Keyboard Settings what i founded in Windows.Nothing helped me.The weird thing is that is not happening always,only randomly and sometimes it works just fine all day long or 3 days.Did someone has this kind of issue in the past?I would really apreciate a little help.ThankYou.
