Boardview for the MSI MS-7B79 motherboard at revision 2.0, delivered as a ZIP archive of 1.17 MB. Extract it and open the layout in a boardview tool such as OpenBoardView or FlexBV. The view lets you click a pin to highlight its net, locate components by designator and pick convenient probing points, handy when hunting a short or a missing standby voltage. Other revisions of this board are separate files, so verify that rev 2.0 is printed on the PCB before working from this layout.
