Same code after the checks?
Same code after you tried a good CPU, RAM and power supply? Then the fault is on the board itself. It can be a power stage, the BIOS chip or the socket. A board repair technician measures the power rails and reads the BIOS chip.
Code not explained here? Post the code, the board model and the CPU on the NoPowerFix forum and a technician will answer.

In 15 years at the bench we saw too many good devices go in the bin because nobody found the real fault. Our Hardware Specialist and Senior Repair Technicians built these tools so more devices get fixed instead of thrown away. If they helped you, a review helps the next person find them, and your support pays for the next fix.
> goal: Less e-waste · Greener Earth
We find the real fault before parts are replaced, so fewer working batteries, boards and devices end up as e-waste.
