Gigabyte GA-B85M-D3H schematic covering revision R21, presented as a PDF in a 789 KB RAR. Reading through its pages lets you follow the power-on sequence, locate the regulators for each rail and pin down a shorted component on a dead board. Revision R21 is close to the R201 and R202 files in the same family, so confirm the exact revision printed on the PCB. Searching net names in a PDF viewer quickly locates the circuit you need.
