Circuit diagram of the Gigabyte GA-G31M-ES2C motherboard at revision 1.12, packed as a PDF in a 1.19 MB RAR file. Revision 1.x boards can differ from the later 2.x series in power circuitry and component placement, so this document suits only early boards. It is useful for tracing supply rails, measuring test points and identifying shorted capacitors or MOSFETs on the VRM. Extract it and open with any PDF viewer, then confirm that the revision number printed near the PCI slots or board edge reads 1.12.
