Some friends encountered a yellow exclamation mark when they came into contact with the PCI Simple Communication Controller, and expressed a headache. Today, the editor has specially shared a tutorial on how to deal with the yellow exclamation mark on the PCI Simple Communication Controller. I hope it can help everyone.

Open the Device Manager, right-click "PCI Simple Communications Controller" and click Properties in the drop-down menu

In the opened "PCI Simple Communications Controller Properties" window, it is displayed: The driver for this device is not installed. Click to update the driver.

In the new window, left-click: Browse my computer for driver software

In the next Update Driver Software - PCI Simple Communications Controller window, click: Select from the computer's device driver list, and then click: Next

In the next Update Driver Software-PCI Simple Communications Controller window, click: System Device, then click: Next (N)

Next, left-click on (Standard System Devices) in the Manufacturer column of the box. (It must be a standard system device demarcated by the red line, not another one!), then click: Next (N)

At this time, a warning window will pop up: Update driver warning window, ignore it, click Yes.

This will appear: Windows has successfully updated the driver file, click Close

The above explains the operation process of the yellow exclamation mark when the PCI simple communication controller appears. I hope friends in need can learn from it.
