Archive for the ECS 865GV-M8 motherboard, revision 3.1D, packed as a 1.06 MB RAR file. The name gives only the model and this fairly specific revision code, with no hint of the documents inside. If it contains a schematic, use it to follow power sequencing, check the CPU VRM and locate the clock or reset signals on a dead board. Revision 3.1D should match the marking on your PCB exactly, since earlier 865GV-M8 revisions may differ in component placement.
