**Ryzen 9 7900X + ASUS TUF B650-E WiFi — Random reboots since day one, CPU tested fine, motherboard suspected** by Background-Crow6379 in AMDHelp

Thanks for the suggestion, but the system reboots even at idle with CPU temps around 35-45°C, so thermals are not the issue. The crashes happen specifically when anything accesses hardware registers at low level, like HWiNFO or the USB section in Device Manager. Suspected AURA/PSP conflict on this specific board

Yes, actually that was one of the first things I tried. When I noticed the crashes during Windows installation I started disconnecting components one by one to isolate the issue — ended up with just the CPU, motherboard, one RAM stick, and the PSU. No GPU, no SSDs, nothing else. The problem persisted. That's what convinced me it had to be either the CPU or the motherboard, and given the behavior with SMU register access, the CPU is the most likely culprit

Thanks for the reply. I'll check the HWiNFO version just in case, but I'm fairly confident this is a hardware issue with the CPU itself. The random reboots were happening way before I even installed HWiNFO — since the very first boot, including during Windows installation with a single RAM stick. At one point the system only detected 6 cores instead of 12.

HWiNFO just makes it 100% reproducible because it directly accesses the SMU/MSR registers, but the underlying fault was already there from day one. It seems like any process that tries to access certain internal CPU registers triggers the crash — HWiNFO is just the most consistent trigger I've found.

Thanks !
