Hi,
Mainly because your motherboard has been EoL since mid-2021 (in any case, even for current motherboards, the firmware/drivers I offer are very often more recent than what is offered on the motherboards support pages).
You need these firmware/drivers for your
ASUS PRIME Z390-A motherboard :
- Intel Chipset Drivers
- Intel MEI Drivers (Drivers Only)
- Intel SATA AHCI-RAID Drivers (Drivers Only) :
Drivers - 2xx/3xx
- Intel Ethernet Drivers (Drivers Only) :
DDrivers - I217/I218/I219
You have an ASUS PRIME DTS Headphone:X v1 motherboards, so :
You need Realtek Audio Drivers (UAD - ASUS TUF/PRIME DTS HPXv1) from the first post of the thread.
Follow scrupulously your CLEANUP process then your INSTALL process, for the next drivers packages that I would release, you will can directly follow your UPDATE process.
