Hi,  That error is System BIOS has halted due to Non-Maskable Interrupt (NMI) reference link [URL] Do one of the following: 1) If new hardware has been added, remove the new hardware and restart the server, 2) Turn server off and back on using the power button, or 3) Remove and reapply server input power.   Please try to do minimum POST process that is removing everything internally and externally but the following •System Board•CPU1 with heat sink (minimum for troubleshooting)•Single DIMM configuration with DIMM in socket A1•Control panel with cable (to the power system on)•Power supply unit (and PDB/PIB)   Hence you can check motherboard works fine or not.    Hope that helps!
