Hi Kingtrivino,
Welcome to Microsoft Community!!
From your issue description I understand that, you are receiving the error: PCI device not installed (code 28). Don’t worry; we will certainly help you.
You encounter error code 28 in device manager for any device if the driver for that device is not installed on your computer.
You might visit ASUS’s website to download the updated drivers for the devices on your computer.
