So, i have a blackwidow tournament edition, i used it for quiet a while, today when i opened my computer and started playing i saw the W key isn't working, it worked like 1 out of 10 presses and even sometimes not at all, i reinstalled razer synapse, downloaded drivers for everthing, disconnected connected, disabled sticky keys and disabled, launched on safe mode, nothing works any solutions? i don't have any good keyboards that i can get and i don't have money for a keyboard atm,i am typing on a microsoft keyboard that came with my 7 year old pc and i am already getting tilted, any help? please help :(
