RAR package for the MSI MS-7693 motherboard, revision 2.0, about 850 KB. Another rev 2.0 archive of almost identical size is catalogued for this board, so check whether this one adds files or is simply a copy. Its contents are not named, so open it to find the schematic or boardview inside. MS-7693 follows MSI's own mainboard numbering. Confirm the revision on the PCB, then use the documents for tracing power rails, checking VRM and chipset supplies and isolating shorts on a dead board.
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.
