Schematic in PDF for the MSI MS-7B28 desktop motherboard, revision 21, archived as a 1.08 MB RAR. MSI numbers its desktop boards MS-7xxx, and this design exists in several revisions. The drawings let a technician follow standby and main power sequencing, CPU VRM, memory and chipset rails, and identify component values. A matching revision 21 boardview also exists, which helps locate parts. Check the revision silkscreened on the PCB before use.
