I believe I may have found the culprit to the random hiveos freezing issue. I will just cut to the chase.
Find in Google search or these forums the BIOS recommended settings for hiveos. I made all the changes but one specifically in the list made did the trick. The CSM setting in the BIOS. Disable that however I don’t know if it may be a combination so just do all recommended.
I have been stable 2 days straight now.
I created this account just to help others as it seems there is no real solution on Google. I hope this helps some.
Cheers.
