RAR archive holding the PDF circuit diagram for MSI board MS-7846 at revision 2.1. The MS-number is MSI's internal motherboard code, printed on the PCB near the slots or edge, and it is the most reliable way to match the drawing to the hardware in hand. Use the schematic to follow supply rails from the ATX connector through the CPU and memory regulators, locate pull-ups and enable signals, and narrow down why a board will not power on. Confirm the board is marked Rev 2.1 before trusting component values, as other revisions of this design exist.
