Circuit diagram of the MSI MS-7402 mainboard, revision 0B, provided as a PDF of about 1 MB with the code 960614 appended, likely a date stamp. The MS-plus-four-digit format is MSI's own numbering for desktop motherboards. With any PDF viewer you can trace power rails, check the VRM and standby circuits, and locate test points while diagnosing a no-power or no-boot fault. Other revisions of this board are indexed separately, so confirm the PCB is marked 0B before using the values here.
