I recently had a problem with my PC while playing a demanding game. I was using a setup that included a 5900XT CPU, 32GB of 3200MHz RAM, a 5070Ti GPU, and an Asrock B550M ITX motherboard. During gameplay, my screen suddenly went black, the fans sounded different, but the power LED remained lit, and I couldn't turn off the computer even by holding the power button. I had to unplug it, and since then it hasn't been able to POST.
I've tried switching out various components, including the CPU, RAM (using only one stick), and GPU, but it seemed like the Asrock motherboard was the issue and it was toast. I bought a new Gigabyte motherboard and tested with my old 5700X, and that worked fine. However, when I put the new Gigabyte motherboard with the 5900XT, it wouldn't respond at all – no LED lights, no response when pressing the power button. But the old 5700X works perfectly with it. I've updated the BIOS to the latest version as well.
I'm wondering if the CPU or motherboard might have failed during that gaming session, possibly taking the other component down with it. I wasn't aware that such failures could happen. Has anyone else experienced this? Also, the original Asrock was quite cheap; could it have struggled with the 5900XT?

Yes, it is possible for a motherboard failure to damage a CPU. If there's a failure in the voltage regulator module (VRM), it could supply too much power to the CPU, which expects a much lower voltage. Your Asrock board was known for having overheating issues, especially with a high-performance chip like the 5900XT, so it's not surprising that it failed during intense usage.
Interesting point! Can these failures happen without causing ongoing issues? I did test my 5700X on the faulty motherboard after the incident, and luckily it works fine with the newer one. Is there a chance it might have been damaged, or since the motherboard couldn't boot at all, it never had a chance to supply high voltage to it?
