Schematic in PDF for the Gigabyte GA-G41MT-S2P desktop motherboard, based on the Intel G41 chipset judging by the model name. The file name gives no board revision, and Gigabyte prints the revision on the PCB, so compare it before trusting component values. The diagrams let you follow the CPU VRM, memory and chipset power rails, standby circuitry, Super I/O and front-panel signals. Any PDF reader opens it, and text search helps jump to a net name or part designator.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @boardview. Enginerys does not host this file.
