Circuit drawings for MSI board MS-7390, compressed to 1.99 MB. The name states no PCB revision, chipset or form factor, so confirm these from the schematic's cover page. MS-7xxx is MSI's numbering format for desktop mainboards, and the code with its version is printed on the PCB. Use the document to map connectors and test points, check which components a shorted rail feeds, and confirm the expected voltages around the BIOS chip, clock and super I/O when a board will not power on or POST.
