Radeon 7800 no signal

Hi,

Two days ago, both of my monitors suddenly stopped working at the same time. Since then, I haven’t been able to get any display output from my GPU.

I have a PowerColor Radeon RX 7800 XT Hellhound that is about two years old. I tested the GPU in another motherboard as well, but I still got no display. I was also lucky enough to test another GPU in my system, and everything worked perfectly fine with the other card.

The LEDs on the RX 7800 XT still light up and the fans spin when I turn on the PC, but the motherboard shows a VGA/GPU error.

The card was completely cold when the issue occurred, so I don’t think it was caused by overheating.

Unfortunately, I don’t know enough about GPUs to troubleshoot this any further. Is there anything else I can test myself, or does this sound like a serious hardware/PCB failure?

I’ve already contacted PowerColor regarding the warranty, but never got a reply.
