Many Asus users have complained about the “Missing ACPI Drivers” error prompt appearing on their PC. 

The problem usually occurs when you have updated Windows on your PC. On every reboot or startup, the ACPI driver missing error appears as ACPI is responsible for managing PnP (Plug n Play) devices connected to your device’s power source.
