Plz help my Razer Blackwidow keyboard is key spamming

I bought this keyboard during vacation but when every I plug the keyboard in it light up normally but for some reason after like 5 minutes later the bottom row changes color and the key start to spam. If I plug and unplug it, it still spams. I have to wait about 30 or more minutes to plug it back in so I can work but then it happens again. I try test on other computers and it did the same thing, I try to install and reinstall drivers and complete wiped synapse but it still does the same. What can I do to fix it? I would really appreciate if you can help.
