RX580 runs without a screen yet launches Windows with sound playing at startup.
My computer isn't showing up but it boots into Windows. I used Ctrl+Alt+Shift+B to reset the graphics card, but nothing appears. Checked all cables and connections, even replugging everything. Tried using a different PC and restarted it six times before shutting it down.
This GPU feels like it's been around for a decade, and it looks like it's reached the end of its life...
You've already tested various cables on a working monitor and swapped the card across different towers. It seems the issue persists. If you have another card, consider re-flashing its vBIOS using AtiFlash, though it's possible the card may no longer be functional.
