Schematic in PDF for an MS-7420N1 mainboard, revision 0D, with the extra code 970609 in the name, which looks like a date or build stamp. The MS- prefix followed by four digits is the numbering MSI uses for its own desktop motherboards; the N1 suffix marks a variant of the base design. Any PDF reader opens it, and the pages let you trace power rails, follow VRM and standby circuits and find the parts behind a short. Check that the silkscreen on the PCB shows the same model and 0D revision first.
