I was running 5950x stable for a while with latest chipset and bios drivers under Windows 11. I recently upgraded my cooler and started getting random reboots when downloading files or opening applications. I updated the bios from beta to non beta: BIOS 7D53v13 with AGESA ComboAm4v2PI 188.8.131.52. I also had the latest AMD chipset drivers. Now the BSODs and more frequent to a point where sometimes it happens before logging to Windows. I tried different things but the only thing that helped was disabling PBO. Any ideas or suggestions are appreciated as I am quite worried the CPU is faulty.
This is the full list of my components:
