MSI MS-7246 motherboard schematic marked 2-2, which likely refers to revision 2.2, in a 1.27 MB PDF file. The MS-7 prefix follows MSI's desktop board numbering. Use the document to trace power rails back to their PWM controllers and MOSFETs, follow the power-on sequence and find components on a rail that reads shorted. Open it in any PDF viewer. Because several revisions of this board exist, compare the version printed on the PCB before you trust component locations.
