Schematic in PDF form for the Gigabyte GA-P31-ES3G desktop motherboard, revision 1.1A, packed in an 890 KB RAR. The P31 in the model name refers to the Intel P31 chipset. Technicians use such diagrams to trace the CPU VRM, memory and chipset power rails, follow power-on sequencing and find where a short to ground starts. Gigabyte changed parts between revisions, so compare the revision silkscreened on your board with 1.1A before relying on values or component positions.
