Circuit diagram for MSI board MS-7B84 at revision 2.0, a PDF compressed in RAR. Use it to follow the CPU VRM, memory power and standby rails, check how the Super I/O and power button signals sequence the board, and identify parts near a suspected short. MS- is MSI's internal project numbering for motherboards. Compare the revision silkscreened on your PCB with 2.0, because revisions 1.x and 2.x of this board differ and their schematics are not fully interchangeable.
