GPU Fans Running Full Speed/No Display

I built a new PC about 2-3 weeks ago and the problem mentioned above occurred yesterday. When I boot up the PC the GPU fans start running at maximum speed and the monitor shows no display. It happened when I tried booting up a game.

I’ve tried re-seating the GPU and updating drivers by plugging in the DP cable to motherboard and both have not fixed it.

Can I please get some help or advice, thanks.
