Top Free Computer Hardware Detection Utilities & Monitoring Tools

If you want to know about the various technical details about your installed computer hardware then you need special tools or utilities for them. There are some big professional utilities available that provide you the information about your system hardware but the problem with them is that they are paid and requires installation on your computer. This means first you have spent some money on them and then they eats up space on your hard drive. Also, some of these programs are trial version and you can use them for a certain limit, after which you have to buy the license key for full usage.

So, here I am going to list down some of the best tools or utilities for windows that are completely free, requires no installation (standalone/portable), have very small size or footprint and provides you the complete hardware details about your computer hardware, that includes your CPU, Motherboard, RAM, Graphics Card / Video Card, Hard Drive, Sound Card and other components installed in your computer. Some of these utilities or softwares can also read the sensor information and provides you the temperature reading of that component for monitoring purpose. These utilities are also known as system info tools, hardware detection tools, PC info tools, windows hardware info utilities or system monitoring tools.

Note: These free system information tools cannot provide information about your PSU because power supply does not contain any sensors and it does not require any drivers for its working. This is due to the fact that it is not connected to your operating system or system BIOS directly or indirectly.
