MSI MS-7589 motherboard data, revision 0A, in a 1.39 MB RAR archive. The name does not say what documents are included, though schematic and boardview material is typical for MSI board codes. Confirm the MS-7589 marking and REV 0A on the PCB, because a different revision can change component placement and values. With a match, the files help you check power rails, trace the power-on circuit through the Super I/O and locate shorted capacitors or failed MOSFETs.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @IT_SERVICE_WORLD. Enginerys does not host this file.
