System Information Viewer (SIV)

System Information Viewer (SIV) is a free lightweight system information and diagnostic utility that provides users of all knowledge levels with incredible insight about the state of the hardware present in their desktop or laptop PC.



Developed by a single software engineer, this comprehensive app is distributed online in a portable form that allows users to take advantage of this app without an official installer, registry changes, or need for the app to always be run from local storage.

The user interface of the System Information Viewer can be described as crowded and densely packed with the information, but to the trained eye, this app only maximizes the display area of its window by presenting the incredible amount of valuable information.

The app featured a tabbed interface (with each tab being called a module), with the primary tab showcasing the in-depth information about the CPU, RAM, and motherboard. This includes current work frequencies, cache sizes, hardware utilization, power usages, temperature, memory timings, and much more.

Other tabs that feature a similar amount of in-depth information are accessible on the bottom edge of the app are Machine, Windows, Hardware, System, Devices, Network, and TCP/IP. It is important to note that default information data can be exchanged with a wide array of additional diagnostic tools with the simple use of the right-click menu.



The app can even be used for browsing of currently installed fonts, drivers and DLLs, stability or networking troubleshooting, or even as a monitoring tool that can help you detect hardware instabilities of or onset of hardware faults.

Data collected by this app can be exported via a built-in clipboard tool, or even saved as a bitmap image of the entire app UI.

Built from the ground to be a comprehensive solution that can serve both novices who just want to easily monitor the state of their hardware and seasoned PC technicians who demand a wide array of information needed for troubleshooting hardware and software faults, this single application can become one of the most valuable system information utilities on your PC.

System Information Viewer (SIV) is 100% FREE and is optimized for all modern versions of Windows OS.
