Boardview for the ASUS Prime A320M-C R2.0 desktop motherboard at PCB revision 1.01, archived as a 343 KB RAR file. A320 is AMD's entry-level AM4 chipset, and a separate file exists for revision 1.00 of the same board, so check the marking on your PCB to pick the right one. Open the extracted layout in a boardview viewer to locate components, view nets, and probe test points while diagnosing VRM faults, missing standby voltages or shorts on the main rails.
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 @BoardSchematic. Enginerys does not host this file.
