Schematic for the MSI MS-B9091 board at revision 1.0, a 1.84 MB PDF. The name gives no retail model or chipset, so check the title block for details. The MS-B prefix differs from the usual four-digit desktop numbers and may indicate a different product line, but confirm against the board itself. Use the document to trace power rails, check regulator enable and power-good signals, follow connector pinouts and locate a shorted component. Verify the number and revision printed on the PCB.
