My problem appears to have been fixed and the computer is now fully assembled again, since December. Looking back, there were likely two or three issues: 1/ The PCI-e power connections were poorly managed and pressed against the case, eventually melting and causing instability. 2/ The PCI-e riser got damaged due to a loose screw on the motherboard's back, possibly pushed in by the graphics card. I don't know how this happened since I never removed or touched that part. 3/ The same loose screw might have created short circuits between the PCI-e riser and the motherboard. To fix this, I upgraded to a new PCI-e riser from Formd, which resolved the problems quickly. Switching from PCI-E 4.0 to PCI-E 3.0 in the BIOS also cleared everything. Since then, everything has worked perfectly.

I replaced my damaged PCI-e power cables with ones made by DreambigbyRayMOD on Etsy. I re-secured the loose screw and used electrical tape to reinforce it. This not only prevents future looseness but also stops direct contact. I’m grateful to @Skiiwee29 for highlighting the riser issue, and I’d recommend investing in a dedicated test bench and PSU tester for better troubleshooting.

The lessons I learned: - Always verify components before use, inspect and test them. - Be mindful of cable limits; avoid overstressing them. - Don’t hesitate to disassemble parts when troubleshooting, especially in compact builds like mini-ITX.

I know these steps were important, but I wish I had followed them. It was frustrating, but it taught me to be more careful. Don’t be like me—don’t take things for granted!
