MSI MS-7A38 version 4.0 motherboard schematic, packaged as a RAR containing the PDF diagrams. With several MS-7A38 revisions in circulation, match the version number printed near the board edge to 4.0 before relying on component designators or values. Repair work it supports includes measuring rails at controller outputs, tracking down a shorted phase MOSFET, following the power-on signal chain and checking the BIOS SPI chip supply. Any archive tool such as 7-Zip extracts it, and a regular PDF viewer displays the sheets.
