MSI MS-7396 board files in a 1.01 MB ZIP. Nothing beyond the model code appears in the name: revision, chipset and contents are unspecified. Archives of this size often hold a single schematic or a BIOS dump. With a schematic you can find test points, check the standby and main rails and track down a short. If it is firmware, make sure the image size equals the flash capacity, read the existing chip with a programmer first, and confirm the MS-7396 marking on the 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.
