DxDiag: Get information about the system and devices of the computer
DxDiag is a system tool for getting system information, for obtaining the information you need to troubleshoot video and audio problems related to computer hardware. The DxDiag tool is built into the Windows operating system.
DxDiag (DirectX Diagnostic Tool) provides detailed diagnostic information about your computer’s configuration, which you can use as a reference for troubleshooting problems.
DxDiag will show basic technical information about the computer: computer name, operating system version, language used, motherboard model, BIOS version, processor used, amount of RAM, etc.
There are quite a few programs for obtaining information about the system and hardware of a PC, there are articles about some applications on my website.
With the help of the DxDiag diagnostic tool, you can get basic information about the components of your computer without using other programs. In most cases, this information will be enough, although more detailed information can be obtained with the help of specialized programs.
