I will check it and update, Last week I got another WHEA lol. This time not related to a reboot. Again no signs of instability.
Also I saw a new BIOS update so I will install it too.
Thanks!
UPDATE
I got something interesting:
I did convert that hex string to text (didn't thought about that lol)

The highlighted text is my data HDD. Could it be the issue??? It is present on all events The drive seems to be fine per SMART. The orange text seems to pinpoint to a SATA port (?)
