I returned from a two-week vacation and my PC now powers on with the motherboard's orange DRAM indicator lit, but it will not POST or show anything on screen—not even the BIOS. I've tried reseating the RAM in every slot, testing the modules individually and in pairs, and waiting for DDR5 memory training. I also updated the BIOS using Flashback, reseated the graphics card, replaced the CMOS battery, cleared the CMOS, and reseated the CPU in case the cooler was applying too much pressure to the memory controller. I don't have spare RAM, another motherboard, or another CPU available for testing. The system has a Ryzen 7 9800X3D, an RTX 5080, and two 32GB Corsair Vengeance modules. Could the motherboard have failed, or is there another recovery step I should try?

It may still be performing DDR5 memory training, especially with 64GB installed. Leave the system powered on for a significant amount of time—possibly 15 minutes or even a couple of hours—before shutting it down. Also make sure the two modules are installed in the second and fourth slots from the CPU socket, usually labeled A2 and B2.
I left it running for about an hour previously, but the orange light never cleared and there was still no display.
