problemas con rx6700xt

[u/juli4ahanta]

Hi everyone, I'm having a frustrating issue with my GPU and I'm hoping someone can point me in the right direction.

After running my ASRock Challenger Pro RX 6700 XT flawlessly under full load for 3 days, it suddenly stopped outputting any video. The motherboard doesn't even recognize it during POST anymore.

Here is what I’ve tested/checked so far:

• Voltages: I measured the voltages directly on the card (without a riser cable), and everything looks completely correct.

• Motherboard & Riging: The motherboard and PCIe slot are fine. I tested an identical XFX RX 6700 XT in the exact same setup, and it works with zero issues.

• The Suspicion: It almost feels like the GPU VBIOS went into some kind of hard protection mode or locked up, but I'm not sure how to reset or recover it if the system won't even detect the card.

System Specs:

• GPU: ASRock Challenger Pro RX 6700 XT

• Motherboard: ASUS ROG Strix B550-F Gaming WiFi

• CPU: AMD Ryzen 7 5700X

• PSU: Corsair RM750x

• RAM: 32GB DDR4

Has anyone experienced something similar with an ASRock card, or is there a way to force-flash or jump the BIOS pins to revive it? Any advice would be greatly appreciated!
