PDF schematic for revision 5.3 of the MSI MS-7817 mainboard, archived as a 1 MB RAR. Opening it in any PDF reader lets you search net names, follow power sequencing from standby to main rails, and identify the MOSFETs, PWM controllers and protection parts involved in a fault. The MS-7817 code is MSI's own board designation, printed on the PCB near the slots. Check that your board carries the 5.3 revision marking, since other revisions of the same design may use different components or circuit topology.
