Revision 1.0 schematic of the MSI MS-7302 motherboard, saved as a 1.30 MB PDF. Boards numbered MS-7xxx belong to MSI's desktop line, and the revision is usually printed next to the model number on the PCB. Use this document to trace power rails back to their controllers, verify BIOS chip and connector wiring, and find the component responsible for a short. A 0A edition that references the RS780 chipset is also listed, so check your board revision to use the matching drawing.
