Some ASUS users have reported a PCI device not recognizing issue recently. In Device Manager, under Other devices, they see a device named PCI Device with a yellow exclamation mark on it (shown as the above screenshot). If you’re experiencing the same issue, you may want to know what a PCI device is and how to update the driver for this device. Read on to find the answer.
What is a PCI Device?
PCI stands for Peripheral Component Interconnect. A PCI device is any piece of computer hardware that plugs directly into a PCI slot on the motherboard.
Examples of PCI devices:
- Base System Device
- PCI Data Acquisition and Signal Processing Controller
- PCI Simple Communications Controller
- PCI standard ISA bridge
- PCI-to-PCI Bridge
- SM Bus Controller
When you see a yellow mark on the PCI Device in Device Manager, it means the driver for one of the PCI devices is not installed correctly. To remove the yellow mark, you need to update the driver. To update the PCI Device driver, you just need to update the chipset driver. If you’re not sure how to do it, continue to the next section for the full guide.
