PDF circuit diagram for the Gigabyte GA-H77-DS3H motherboard, labelled R102, which likely denotes board revision 1.02, provided as a 1.59 MB RAR archive. Schematics like this are used to trace power rails, locate the VRM controller and MOSFETs, and follow power-good and reset signals during a no-POST diagnosis. Extract it and open it in any PDF reader. Check the revision silkscreened on the PCB against this document, since other versions of the same model exist.
