I bought the amd radeon 390 but it keeps displaying "No display". I can see my display if i put the vga in the cpu.
CPU: i3 something(Can look it up if you want)
GPU: AMD Radeon 390.
Motherboard: ASRock b75 pro3.
Power Supply: 550W

ps the fans on the 390 is not spinning.
 


make and model of the power supply? plugging in all pcie slots on the video card is mandatory, did you do so?


because a 390 really needs a good 650w unit
 


Im putting the cable in the gpu, and i dont think i have 2 different pins so maybe thats the problem
