Hello, I have a 470 mining edition with a DVI video port. This GPU is recognized by the PC, sometimes it can work with load and be used without problems, but from one moment to the next it can stop giving video and stop being recognized by the PC. I tried changing the BIOS, changing the BIOS chip, reflow in the core and memories, it should be noted that at all times the GPU has all the voltage rails in perfect condition. It was tested on another PC while in mine it was not recognized and if it detected it, it no longer works correctly. My PC is an i5 with a 4th Asrock motherboard, the PC where it was tested as an alternative is a 5th Ryzen. What else could I try to solve it?
