PCI not recognized in Windows

This problem occurs when Microsoft Windows does not correctly detect the chipset display or other types of device drivers that remain with the classic yellow exclamation point in the Device Manager Control Panel window of the operating system.

Motherboard or chipset drivers not installed or obsolete

You must download and install the latest version of the chipset and video card drivers. If you have the motherboard CD this will contain the chipset drivers. Otherwise, you can find the drivers for all the manufacturers, or more comfortably, as usual with the Driver Detective program.

Damaged or missing video card driver

If installing the latest chipset or motherboard driver does not solve your problem make sure you have the latest drivers installed for your video card and other hardware components. Remember that almost every month new updated drivers are released, especially for new versions of Windows and patches for older versions such as Xp and Vista.

Another PCI device that Windows can not identify

If you have tried both steps and the Windows Device Manager still contains an unknown PCI device or yellow exclamation point, your device may not be properly identified. It may also not be compatible with the installed version of Windows because it is too recent.

If you are trying to install a new hardware device and are not recognized, we suggest downloading the latest drivers for that device.
If you have just finished reinstalling Windows on your desktop or laptop PC and are receiving an unknown device message, you may want to manually identify the PCI device through the registry that you can display through the Regedit command written in the Start menu command line of Windows.
