The information that this page provides – and related information
This section of this website provides detailed information on computer motherboards (also known as mainboards), the printed circuit board (PCB) that is the main component of a desktop or laptop computer. It covers how the motherboard integrates with the desktop-PC case, the power supply unit (PSU), the RAM memory, hard disk or SSD drive, optical CD/DVD disc drives and the subordinate PCB components, such as the graphics card and sound card – and the peripheral devices (USB devices such as external hard disk and optical drives, printers, flash drives, etc.) All of those PC components and peripheral devices have their own sections on this website under the Hardware menu.

Information on what hardware and software is installed on a computer
If you need information on what hardware and software is installed on a computer, the Belarc Advisor from belarc.com is a free tool (look under Free Download on its website) that identifies a Windows computer’s hardware (motherboard, graphics card, hard disk drive(s), DVD drive, etc.) and software (version of Windows, applications, etc.) and even software licences, including the Windows Product Key, which is always required when reinstalling Windows.
The miniaturised motherboards used in laptop computers are not dealt with in this article because they are only accessible by specially-trained technicians or people with the required know-how and, since they are not sold by computer stores, can’t be upgraded unless the upgrade is provided by the laptop’s manufacturer. You are stuck with the motherboard that is in a laptop computer unless it develops a fault and has to be replaced by its manufacturer with the same model of motherboard. However, second-hand laptop motherboards are being sold on auction sites such as eBay, but they may or may not be available for your make/model of laptop.
