Report content

The report consists of three sections.

The first contains the self-analysis of the report by UserDiag, with advice to resolve identified issues.

The second groups together information such as software configuration and computer components.

The third part offers graphs recorded during the various tests. This allows detailed analysis of metrics such as temperature, frequencies, voltages, or component consumption.

A reliable diagnostic via HWiNFO

UserDiag uses real-time monitoring technologies provided by HWiNFO.

This integration allows accurate and reliable readings of frequencies, temperatures, voltages, and other metrics.

Other specialized tools are also used during component tests, such as FurMark (graphics card), Prime95 (processor), or diskspd (storage).
This is done with the permission of their developers or via their license. Thank you!
