Gabriele Rinetti The problem you are experiencing may stem from a compatibility conflict between the newly updated Windows/AMD drivers and the SER8 factory default chipset drivers.
To solve the Chipset driver compatibility issue, please update the latest BIOS V035.P8C0M0C15.16. This BIOS update completely fixes the compatibility conflict, allowing your device to normally support the latest Windows OS updates and official AMD drivers, and permanently resolve problems of system freezes, stuttering and random reboots.
Please repeatedly press delete key as soon as you turn on the PC, go to BIOS. Please send us a picture of the Main page, we will check if you need to update the BIOS.
