MSI schematic for the MS-7778 motherboard, revision 0A, delivered as a PDF inside a 1.77 MB RAR. MS-7xxx is MSI's numbering for desktop boards, and the same board is often supplied to OEM brands. Use the diagrams to trace VRM and standby rails, check the power-on sequence, and identify the parts around a shorted line or failed circuit. Open it with any PDF reader. Confirm the revision printed on your PCB matches 0A, since component values and nets can change between revisions.
