Updates on this matter? Still unclear. I've been struggling with the same issues for a few years now. My PC occasionally crashes when stressing the GPU, though it doesn't always happen. Over time, I've tried replacing parts, filing for returns, and checking each component one by one. I even encountered several dead PSUs, which made me suspect power issues in my home setup. The SSD and case seemed safe after using Kapton tape for insulation. Outside the case with the riser cable still works fine. It's similar to what you're experiencing. My current system includes a Ryzen 5700X, MSI 4070 Ti Corsair 3600MHz RAM, Gigabyte B550i Aorus ADATA SX8200P NPIP, and drives from T-FORCE and Corsair SF750 PSU.
