This post is going to explain what PCI drivers are. And if you are Missing them, how can you fix missing PCI device drivers?
With Windows 10, it has become far much easier to repair a broken driver. Or install a new one altogether compared to the previous generation of windows where you had to actually nail down the exact name of the PCI device and controller. And then fetch the drivers manually from some shady websites.
With Windows 10’s ability to discover and repair broken PCI drivers, we are going to fix any gadgets that are connected to your PC and are having trouble finding drivers for them.
What is a PCI device?
Peripheral Component Interconnect is what PCI stands for. This is basically an interface that is used by all your peripheral devices to talk to your computer OS, Windows in this case.
These PCI devices include but are not limited to, network cards, sound cards, and so on. All these devices make use of the PCI interface to translate and pass information to and from the processor to the OS.
Now all this information is carried by something that is called a BUS. It is not hard to spot it on the motherboard. It is a long, copper-colored, and slightly raised slot on the motherboard. Your PCI devices are plugged into these PCI slots on the motherboard.
These PCI slots are versioned over the years. The latest is the PCI express which delivers the fastest connectivity between the PCI device and the microprocessor on the motherboard.
Are PCI drivers necessary?
Drivers are a necessary piece of machinery in order for them to function properly. Drivers help the hardware communicate efficiently with the software. In Windows OS, you often get time-to-time updates for all your PCI devices. But not for all.
Some drivers are not released for a few of the PCI devices due to incompatibility issues. For such rare and few PCI devices, you will need to manually search, download and install the drivers.
Since it is imperative for the PCI devices to communicate with the OS, the PCI driver is the cog that will help run things smoothly without us even noticing.
You can find all the PCI devices that are not functioning optimally under Device Manager. And look for any devices that are showing a yellow exclamation mark inside a triangle.
This mark indicates that the device is malfunctioning either due to a lack of drivers or it is physically not working at all. So, there may be a hardware issue with the device.
