Take all components apart and remove the system from its case. Place it inside the motherboard enclosure. Insert the CPU, cooler, and RAM. Attach the 24-pin power connector and the 4/8-pin CPU power cable. If you lack a MOMO with a button, short the power pins. Otherwise, ensure access to the BIOS—any issues suggest a problem. Repair requires a fine-tipped soldering iron and flux. Apply flux to the damaged spot, then gently rub it with the iron while soldering. Be extremely careful to avoid creating bridges.
