Windows Device Manager base system device under other devices

Windows 8 device managerAfter installing or reinstalling Microsoft Windows, you may encounter one, two, three, or more base system devices under the Windows Device Manager. This occurs when the drivers for the card reader on your laptop or computer is not properly installed. To correct this issue, locate the drivers on media that came with the computer or on the computer manufacturer's website. Many manufacturers will list these drivers under the removable media or chipset section.

This issue can also occur for USB ports on the motherboard, when the installation of Windows does not recognize the USB ports correctly. To resolve the USB ports issue, you can also try to locate the USB drivers on media that came with the computer or on the computer manufacturer's website.

If the issue still exists after installing card reader drivers (if your computer has a card reader) and USB port drivers, there is another system device that Windows is not recognizing correctly. Check the manufacturer's website for other drivers that are available for your computer. Download the drivers and install each one, which should resolve the issue and get all the system devices in your computer recognized by Windows and the Device Manager.

Tip: Even if drivers are already installed for some devices on your computer, it is still a good idea to download and install the latest drivers. Installing the latest drivers can help resolve other issues and help your computer to run more efficiently.

After installing all available drivers for your computer, if the issue remains, there is likely something wrong with one of the hardware devices in the computer. It is recommended that you take your computer to a repair shop to determine if a hardware device is not working correctly and needs to be replaced.
