Razer Cynosa Chroma acting really weird

So I bought my Razer Cynosa Chroma keyboard less than a year ago. It worked fine until yesterday. All of a sudden, when I booted up the computer, it started acting up. When the keyboard is idle, it does the Wave setting. When I press a button, it suddenly switches to a reactive green setting and doesn't input into the computer at all. I've tried un-installing and re-installing the keyboard drivers and Synapse, but nothing changed. I plugged in a different (non-Razer) keyboard and it worked fine. Note that I have a Razer mouse that is still working great. Is my keyboard just broken? Do I need a replacement?
