recently i have unplug the DVI cable from the rx 570 to test another device with the monitor, after plugging it again there is no signal i have rebooted the pc but still no signal, then i tried the integrated graphic with vga cable, the rx 570 is detected by bios, windows also recognize it, i can change settings with amd wattman(fan speed/voltage...) gpuz also show informations about the card and sensor, i have done aida64 gpgpu benchmark, the results are normal (max temp 62C°) no throttling no problem but still no signal when plugged to the monitor. i have tested the card in the second pcie x16(wired x4) same problem, dvi cable tested with satellite receiver using hdmi adapter and it work fine, i testetd the hdmi adpter with the GPU, same probleme. i have tryed to flash the vbios but atiwinflash say that the card had the same rom, then i used command line to force the flash, the card was succesfuly flashed but the problem remain the same. i have this card for some months now, i dont know what hapning the card is fine and work with benchmark utilities but no signal.

Please help me figuring out what is the problem

Go to your BIOS by spam pressing F1, F2 or F9, and look for Advanced Boot Options Priority or Boot Mode Selection then choose [Legacy Only]. Save & Reboot. See if that works.
