I've hand built dozens of PCs over the past 20+ years. Never had a problem that wasn't just me being stupid.
I wanted to upgrade a low-end-ish utility computer in my house. I bought an ASUS Prime B450M-A II motherboard and some G.Skill memory to go with it. I re-used the existing GPU & NVME, and swapped the CPU from another box. All of this is/was known-good hardware.
After it was rebuilt, it would boot fine, and then after a random amount of time it would lock up hard reporting a ton of EXT4 FS errors on the console. Booting from a rescue disk and scanning the NVME always reported zero filesystem errors. I did this several times. I reset the BIOS to defaults, updated the BIOS, tried various parameters in the BIOS, moved the NVME from the mobo to a PCIE slot. Nothing changed. Convinced something was wrong with the NVME, I bought a new one and did a fresh OS install. Same problems. Since the GPU was on the same bus, I took a long shot and swapped with one from another box. Same problems. I ran memtest for hours, it never found anything.
The only thing left, that I can think of, is the motherboard. Am I reasonable to attempt to return it? The symptoms are very repeatable, and very specifc. At this point could it be anything else?
