Check the PC case side panel for a printed motherboard model number (often near the PCIe slots or along the edge of the board).
Open your system and look for the motherboard branding/model printed on the PCB.
Use System Information (Windows): `Win + R` → `msinfo32` → look for “BaseBoard Manufacturer” and “BaseBoard Product”.
Use Command Prompt (Windows): `wmic baseboard get product,manufacturer,version,serialnumber`
Use PowerShell (Windows): `Get-CimInstance Win32_BaseBoard | Select-Object Manufacturer,Product,Version,SerialNumber`
Use System Report (macOS): Apple menu → About This Mac → System Report → Hardware → select “Controller”/“Mainboard” details.
Use Linux (terminal): `sudo dmidecode -t baseboard`
Use Linux (alternative): `sudo lshw -class motherboard`
Use a hardware info tool (Windows/Linux): CPU-Z (Motherboard tab), HWiNFO, Speccy, or similar.
If you have a prebuilt PC, check the exact model number on the manufacturer’s support page (it often lists the motherboard model).
Cross-check by matching BIOS version and motherboard model shown in firmware/BIOS screens at startup (if available).
