Hello, USERMAC.
May I ask if the model is the ROG MAXIMUS Z790 HERO? Do you have a blue screen when it happens? What is the BIOS version in current use?
Are there any software and hardware changes before this situation occurs? Did you update the ME firmware before updating the BIOS?
Please try testing by defaulting the BIOS settings first, and make sure all the drivers, including the ChepSet driver, are in the latest version.
Thank you.
Due to the ongoing regional holidays, my responses may be slightly delayed.
Thank you in advance for your patience. 🙂
