This is frequently caused by a missing "Power Good" signal. Use the schematic to find the or ALL_SYS_PWRGD nodes. If one voltage rail is slightly out of spec, the controller will reset the system to prevent damage. No Video / RAM Not Detected
Having the schematic allows you to perform "point-to-point" continuity testing. Here is how to use it for common issues: No Power / No Fan Spin foxconn 115xdbp motherboard schematic best
A schematic tells you how components are connected, but a shows you exactly where they are physically located on the PCB. For the Foxconn 115xDBP, having both the schematic and the Boardview is the "best" setup for a fast repair. This is frequently caused by a missing "Power Good" signal
