I bought a rx 580 2048 sp graphics card but the temperatures were high, I decided to undervolt but the screen just went black and when I restarted it stopped giving an image, I already tried with 2 motherboards and my power supply, they are in good condition, the graphics card turns on and works together with its fans, but as I already mentioned, it is unable to give an image, I already let it rest and remove the battery from the motherboard, disconnect the power source and its cables but nothing, use the official program of amd Radeon to do the undervolt, when turning on my pc it cannot Detect gpu
