MSI B85M PRO-VD motherboard documentation for board number MS-7A01 at revision 1.1, supplied as a RAR archive of roughly 849 KB. The model points to the Intel B85 chipset. The name does not say whether a schematic, a boardview or both are inside, so open the archive to find out. Check that the PCB reads MS-7A01 rev 1.1 before measuring, since MSI revisions can change parts and placement. Such files help trace VRM and memory power rails, locate components and isolate a short to ground.
