"Please Power Down and Connect the PCIe Power Cable(s) for this Graphics Card"

I was playing bf1 when I suddenly got a big fps drop, my computer then went to a black screen. I turned it off then back on to see this message on my screen. "Please Power Down and Connect the PCIe Power Cable(s) for this Graphics Card" I've had my computer for over a year now with no problems. My power supplie is Thermaltake sp-750W 80 plus bronze, and my graphics card is a gtx 970.
Considering that my computer worked fine for over I year I fear the gtx970 has committed suicide. I am not knowledgeable when it comes to computers.
any suggestions on a fix? Or do I need to buy a new card?
