Schematic PDF for the MSI MS-7246 motherboard. The 21 in the name most likely stands for revision 2.1. The file is 1.11 MB and follows MSI's MS-7 desktop board numbering. Use the drawings to trace power rails and VRM phases, follow power-on and reset signals, and identify components on a shorted line. Several revisions of this board are catalogued, including 1.0, 2B and 2-2, so match the version on the PCB before relying on part values or positions.
