Find the PCI Device driver
PCI Device is what Windows shows when it knows nothing about a chip. Open its Properties, Details, Hardware Ids, read the VEN and DEV codes, look them up in the PCI ID Repository, then get the driver from your PC maker or the chip maker. The code, not the name, tells you what to install.

The short version
What to install and where it comes from. Every link goes to the manufacturer or Microsoft, never to a copy.
Official files only, nothing bundled
Step by step
Copy the Hardware Ids
Right-click PCI Device, choose Properties, Details, and set Property to Hardware Ids. The first line looks like PCI\VEN_8086&DEV_51A3.
Split the line
VEN is the maker's four-digit code. DEV is the chip. Subsystem codes after SUBSYS name the PC or board maker.
Search the PCI ID Repository
Open pci-ids.ucw.cz, search the vendor code, then the device code. The listing gives the chip name.
Pick the matching page
Intel chipset parts: Chipset INF Utility. AMD: the chipset driver. Realtek or others: your PC maker's support page for that model.
Install and rescan
Restart after install, then use Action, Scan for hardware changes. The entry should be renamed.
Why this entry has the vaguest name
Most unknown devices carry at least a class, so Windows can call them Network Controller or Base System Device. PCI Device is the last resort, used when even that is not enough. The label is not a hint about a missing network, audio or graphics driver. It simply means the chip has not been matched to anything.
Reading the code
A hardware ID has parts. VEN is the vendor, assigned by the PCI-SIG. DEV is the chip. For example, 8086 is Intel and 1022 is AMD. Put those two codes into the PCI ID Repository and you get the product name, such as a chipset generation or a controller. Writing down the name before searching saves time on every later step.
Where the driver comes from
Follow Microsoft’s order. First Windows Update, including Optional updates. Second, the PC maker, whose package is built for your model. Third, the chip maker. Intel says its Chipset INF Utility installs INF files so Windows can show the right name for a chipset part in Device Manager, which fixes a large share of PCI Device entries on Intel systems. AMD ships its equivalent in the chipset driver on its drivers page.
What not to do
Do not download an installer from a site that offers every driver in one file. Do not turn off driver signing checks. If the ID leads to a maker with no Windows driver, the part may be a service chip that needs none, and the entry can be left alone.
Questions
Why does Windows not show a better name?
The name comes from the class code in the chip. A chip with no class or no INF match gets the plain PCI Device label, so Windows has nothing to say about it.
What if the ID is not in the repository?
The list is public and volunteer-built, so new chips can be missing. Use the SUBSYS code or your PC model and check the maker's support page.
Should I use a tool that guesses drivers?
No. Microsoft advises taking drivers from Windows Update or the maker. Matching the ID yourself is quick and avoids wrong installs.
Can a virtual machine show PCI Device?
Yes. Virtual hardware can appear this way until the guest tools from the hypervisor maker are installed.
