Main Reason for Base System Device Issue in Windows 7

Most PC users want to upgrade their computers (desktop/laptop) to run the latest Windows Operating System which is Windows 7 (Windows 8 is scheduled to launch in fall of this year.) However, associated with this OS upgrade are device driver related issues, and one of the most common issues out there is Base System Device Windows 7 problem.

This is because, along with the OS upgrade, the installed drivers (including Base System Device drivers) will be deleted. This means that you will need to install all the missing drivers to your PC after upgrading your OS to Windows 7, thus, you will also need to reinstall the missing Base System Device driver.

However, there are computer manufacturers who still don’t have Windows 7 Base System driver update for computer models. Yes, there are computers that still only have XP driver updates and PC models with only XP and Vista driver updates, making your search for the correct Base System Device driver update a time-consuming and troublesome task.

Also, there are PC users who are not aware that they have Base System Device issues until they start to wonder about the instability of their PC’s performance or after they try to attach an SD card to their PC. So, if you have just upgraded your OS to Windows 7, you can check if you have a Base System Device Windows 7 issue through your Device Manager:

  1. Click the Start button
  2. Right-click Computer
  3. Select Properties
  4. Click Device Manager


Another reason why PC users are being troubled while trying to fix Base System Device issues is because they don’t know what a Base System Device is. So, let us consider the identity and functions of a Base System Device.

What is a Base System Device in Windows 7

The phrase Base System Device is not a real device or PC component. In many computer related forums, the Base System Devices are identified as SD Card Readers, but the phrase ‘Base System Device’ can also be a chipset component.

A hardware device marked by a yellow warning symbol, such as a Base System Device listed under the Other Devices in Device Manager is unusable. This means that its features and functions are disabled. So, you will not be able to use your SD card reader as long as the Base System Device issue is not fixed. The same effect is true when your Base System Device is a chipset component, where your PC won’t be able to use the features of that chipset component while the correct drivers are not yet installed on your Windows 7 PC. You must also remember that chipset components/devices are responsible for enhancing system performance, thus, installing the correct base system device drivers to your Windows 7-based computer, as soon as possible, is very important.
