Schematic for MSI desktop board MS-7359 at what the name suggests is revision 1.0, provided as a PDF of about 986 KB. It helps a technician trace the CPU core regulator, memory and chipset rails, clock generation and reset logic when diagnosing a board that will not power on or POST. Any PDF viewer can open it. Because later 1.1 and earlier 0A and 0B versions also exist, verify the revision silkscreened on the PCB before replacing components according to this diagram.
