HWINFO aside, PC reboots sounds like cores starved for voltage. HWINFO has, in the past, been the cause of WHEA errors, but they fixed the first cause. Get in touch with HWINFO and see if you can have a diagnostic data dump from HWINFO sent once you reproduce the event; they'll be interested to know if it is HWINFO again causing issues.my 5900x on f33 runs 1900 1:1 stable... well mostly 99% as i just discovered a full windows defender scan with hwinfo opened, will reboot my pc at around the 20min mark.
if i don't have hwinfo opened, it completes fine
yes windef full scan uses up to 30% of all cores and take almost 30min to complete lol
