PCI or the Peripheral Component Interconnect is a globally recognized bus for attaching external devices to a system. Without a proper PCI Serial Port, you just can’t plug and play anything. Some users have reported an issue where they are unable to install the PCI Serial Port driver on their respective systems. Starting from a corrupt PCI port driver to even malware may block this driver installation.
1. If you have failed to install the driver for the first time, restart the system and have another go at it.
2. All the driver updates require a system restart to complete. So, try restarting the device after the PCI driver installation.
Fix 1 – Update the chipset driver
You can directly update the PCI driver from the Device Manager page.
1. You can directly press the Win key+X keys together.
2. Then, just click on the “Device Manager” to access the Device Manager utility.
3. When you are there, expand the “Other devices” section and you will see the “PCI Serial Port” in there, carrying a ⚠️ sign.
4. Now, right-tap the “Update driver“.
5. Next, tap on the “Search automatically for drivers” to let Windows search for the proper driver and download-install the same.
Once it is done, don’t forget to close everything and restart your system.
Fix 2 – Try Optional Windows Update
Look for the Optional Windows Update, where the chipsets updates are delivered.
1. Open the Settings window on your system.
2. Now, just click on the “Windows Update” section on the left pane.
3. You will see many options on the right-hand pane. Just, click on the “Advanced options” settings to access it.
4. Now, just tap on the “Optional updates” option to access it.
Now, just check the PCI drivers updates, if there are any.
5. Next, just click “Download & install” to install those updates.
This will finally install the optional webcam drivers on your system.
6. In this case, Windows won’t directly prompt you to restart the machine. You should just restart your machine once.
7. But, when you come back to the Windows Update home page, you may see the “Restart now” option. Tap it to reboot the system.
Once you restart your system, you will be able to install the PCI driver.
Fix 3 – Run a full system-wide scan
Sometimes a single malware file may come into conflict with the installation process of a new driver.
1. First of all click on the 🔍 icon and write down “security” in the search box.
2. Then, tap on “Windows Security” to open Windows Security.
3. On the left-hand pane, tap on the “Home” icon.
4. Next, tap the “Virus & threat protection” to open it.
5. On the Virus & threat protection page, tap “Scan options” to access it.
6. Now, just select the “Full scan” option to select it.
7. After this, tap on “Scan now” to run the full scan.
8. Depending upon the number of files you have on your system, this scanning process may take a while.
Once it is done, close the Windows Security. Reboot the device. Once it does boot up, try to reinstall the PCI driver once again. It should work.
Fix 4 – Run the Hardware and Devices Troubleshooter
You can’t directly find this useful troubleshooter. So, follow these steps.
1. Press the Win key+R keys together.
2. Then put this line there and click on “OK“.
msdt.exe -id DeviceDiagnostic
This will open up the Hardware and Devices page.
4. Now, click on the “Advanced” option.
5. On the next step, just tick the “Apply repairs automatically” box.
6. Then, tap “Next” to proceed to the next step of the solution.
On the next screen, just follow the instructions of the troubleshooter to fix the PCI driver issue on your system.
