This is often a corrupted BIOS or a missing power-good signal. Trace the SPI Flash ROM (W25Q64) pins. Check pin 8 for +3.3V.
The is an entry-level motherboard based on the Intel H61 Express Chipset. It is designed to support Intel 2nd and 3rd Generation Core processors (Sandy Bridge and Ivy Bridge) using the LGA 1155 socket. "Ver 8.0" denotes the specific PCB revision; in motherboard repair, revision numbers are critical because component locations and part numbers often change between revisions (e.g., a Ver 6.0 schematic will not match a Ver 8.0 board perfectly). h61mgv3 ver 8.0 schematic

To help you get started on your specific repair, could you tell me what the motherboard is currently showing (e.g., completely dead, fans spin but no display, loops on/off)? I can provide more targeted voltage test points or component values based on your issue. Share public link that host PDF boardview and schematic files for
Motherboard schematics are intellectual property. Most manufacturers do not publicly release them. However, repair technicians can use them for under fair use / right-to-repair exceptions in many countries.
Completely dead motherboard with no standby LED indicator. 2. PCH Power Rail (+1.05V_PCH) Check pin 8 for +3
It is important to clarify immediately that the refers to a specific motherboard model manufactured by Foxconn . Because motherboard schematics are proprietary intellectual property used by repair technicians, they are rarely found as standard "text documents." They are almost exclusively distributed as large, multi-page PDF files containing circuit diagrams .
