Razer Nommo Chroma serious sound problem

Hi! I'm having serious audio problems with my Razer nommo chroma speakers. They're working fine for anywhere between 1 to 5 minutes and then turn off automatically. While they turn of they make an awfull verry loud noise/sound. At first they were plugged in an USB Hub but also directly in the computer, the same problem occurs. I have no idea how to solve this ans i can't use the speakers at this moment. Please help :)
