So, I have a Razer Blackwidow Chroma since 2014, and im still using it until now, but, since last mont, this keyboard is spamming z key.
However, i've done this things :
- Uninstall Razer Synapse & Driver
- Cleaning Malware and Viruses
- Cleaning the Keyboard itself
But, its still keep spamming. so, what cause this spamming thing & how to fix it?
 


I pulled the z keycaps and cleaned it surroundings, but i dont see anything suspicious, can i remove the switch?
