MSI MS-7820 schematic, revision 2.1, provided as a PDF inside a RAR file of roughly 822 KB. The MS-7820 number follows MSI's in-house board designation, and since MSI often issues several revisions of one board, the revision marked on your PCB should be checked against 2.1. With the diagram a technician can follow CPU and memory supply rails, verify standby and power-on circuits, identify fuses and MOSFETs and work through no-power or no-boot faults. Extract and open it in any PDF viewer.
