Ps4 controller going crazy

I recently bought a Ps4 controller and while I was playing Castle Crashers on steam and it began to vibrate nonstop, just when I paused the game it stopped after a few seconds. It was red some minutes ago and now it turns yellow, goes to red and then blue. It is 100% charged.

Another thing, my PC does not support Bluetooth, so I have to use a cable that charges it to play the game. Without the cable, the controller doens't turn on, just flashes multiple times white then stops. I'm a newbie, need help.
