I recently did a clean install of Windows 10 on my older ASUS P8Z77-V LX motherboard and noticed a yellow exclamation mark in Device Manager under "PCI Simple Communications Controller."

Fixed: Missing PCI Simple Communications Controller Driver for ASUS P8Z77-V LX (Windows 10/11)

Do download the driver from ASUS's official website for this board—the version there (v7.0.0.1144) is from 2012 and often fails to install on Windows 10/11.
