How to Fix PCI Serial Port Driver Not Working Issues Windows on PC

If your PCI Serial Port driver is not working on your Windows computer, then try out the different solutions provided in this article.

PCI stands for Peripheral Component Interconnect. It is a local computer bus, which is used to connect gear to a computer. There is a type of computer link called a serial port that lets you connect your computer to a serial device and send data one bit at a time. It's a piece of hardware that is linked to the motherboard of your computer. Making sure you have the right driver update helps your system's hardware work well.

Your computer stops working right if the PCI card drivers, PCI network drivers, PCI audio drivers, or PCI Drivers for Windows devices are out of date, damaged, or missing. That's why PCI drivers need to be changed. A PCI Device Driver is a piece of software that makes a PCI device work properly. To fix these problems, you need to get the most recent PCI Device Driver for Windows. Hence, here we are providing some of the best ways to resolve PCI-related problems on your Windows systems.

Different Methods to Fix PCI Driver Not Working Issue
Below we have mentioned different ways to fix and update PCI drivers without using any Best Driver Updater Software.

Method 1: Run DISM and SFC Scans

Imagine for a second that the PCI drivers can't be installed because certain Windows Image files are missing or damaged. To resolve any difficulties and proceed with driver installation, you must first perform the System File Checker (SFC) scan, followed by the Deployment Imaging and Servicing Management (DISM) tool.

Method 2: Perform Clean Boot

If the above method doesn’t work in resolving the issue, then you need to figure out whether Windows is damaged or if the problem is caused by external software on your computer. This may be determined by running a Clean Boot, which will ensure that only the necessary applications and drivers are launched. The problem is with third-party applications if installing PCI drivers in Clean Boot Mode is not a problem. Windows and its components are to blame if it doesn't work. The perpetrator must be identified via a process of trial and error.

Method 3: Run The Antimalware Tool

Malware on your computer might be preventing the PCI driver from installing. You need to guard your computer from malicious software and other similar threats. Find the malware and remove it using the antivirus and anti-malware software that is installed on your computer.

Method 4: Update PCI Serial Port Driver

Inspect your Windows installation for any available updates and apply them. Updates for Windows may include the installation of PCI drivers. Device Manager, a third-party application that installs and updates drivers on your PC, is another option for installing drivers. The PCI driver is also available for download and installation on the manufacturer's website. Here are a few steps that will help you update the drivers using Device Manager.

Method 5: Run Windows Troubleshooter

You may quickly and simply solve any internal PC problems with the help of the troubleshooters that are available in Windows 11 and 10. If the PCI drivers still won't install, try running the Hardware and Devices troubleshooter. The problems will be detected and resolved automatically by the troubleshooter. Follow the steps below as they will guide you to use this troubleshooter to fix the problem.
