MSI MS-7678 schematic, version 1.1, for the H67MA-E45 desktop motherboard, provided as PDF in a RAR of about 1.4 MB. It is a later revision of the same design as the 1.0 drawing, so values or placement may differ slightly. Technicians use the sheets to trace power rails, the power-on sequence and chipset signals, and to identify faulty parts near a short. Check the version printed on the PCB matches 1.1 before measuring against the drawings.
