Have you checked that both your motherboard firmware and the graphics<br>
card firmware are current?<br></blockquote><div><br></div><div>Hmmm, it looks like my motherboard firmware is behind. It's a B450 tomahawk mc-7c02 running E7C02 AMS.130 from a few years ago. There have been several updates since then. None of the updates look relevant to this problem and I'm a little reluctant to update motherboard firmware. As for the graphics card firmware, I'm not sure. The VBIOS version reported above is 80.06.10.00.5d.</div><div><br></div><div><br></div></div></div>
