Schematic for the MS-7358 mainboard marked V12, probably revision 1.2, in a 1.30 MB PDF file. The MS-7 prefix places it in MSI's desktop motherboard numbering. A technician uses such sheets to locate regulators for each voltage, check signal continuity between chipset, slots and I/O, and narrow down shorts to individual capacitors or MOSFETs. Open it in a PDF reader and search by net name. Confirm that the revision on the board matches before trusting component references.
