Circuit diagram for the MSI MS-7A39 desktop board at revision 2.0, stored as a PDF inside a RAR file and labelled with reference 00017967. The schematic shows rail generation, VRM controller wiring, chipset connections and SPI flash circuitry, which helps a technician measure test points and narrow down a short or a missing voltage. MS-7xxx is MSI's in-house numbering for desktop motherboards. Before working from it, confirm the board code and version 2.0 on the PCB silkscreen match, since older revisions differ.
