Hi there! Your Sapphire Nitro RX5700XT is showing some power-related issues. It boots up with fans and lights, but after a few minutes the monitor loses signal and the GPU fan stops spinning. The system stays on, though it seems to reset itself quickly—sometimes just a few seconds. You noticed the BIOS logo appears briefly before losing signal, and then it never gets a signal again on subsequent tries.
You mentioned having a Ryzen 5 5500 with 16GB RAM, and another GPU worked fine. Your PSU is 750W, and you ran a stress test earlier that lasted about 20 minutes without problems. Now the stability is gone. You think it might be a power issue with the GPU? Someone could help clarify or share similar experiences. Thanks!
