Schematic for the MSI MS-7798 desktop motherboard at revision 1.0, in PDF form. MSI labels its desktop boards with MS-7 codes, and the revision is normally silkscreened beside the number. These pages help when checking the CPU and memory voltage regulators, tracing the power-on chain from the front-panel button through the Super I/O, or locating a shorted capacitor on a rail. Verify the number and the 1.0 revision on your board first so that component references line up. Viewable in any PDF reader.
