Diagnostic Card Code After Powering On the Motherboard
After the motherboard is powered on, if the diagnostic card code does not change and remains at 00 or FF, it usually indicates that the CPU is not working.
At this point, turn off the power and remove the CPU fan. Carefully touch the CPU with your hand (preferably between your fingers and the CPU, keeping heat sources separated to avoid burns). Slightly press and hold the power button.
If there is still no response and the motherboard does not start, the CPU socket may have discharged. The next step is to determine whether the CPU power supply circuit is faulty.
First, understand the routing of the CPU power supply circuit on the motherboard. Under normal conditions, the CPU power circuit layout is reasonable and located around the CPU area. The CPU uses a 5V power supply. Connect the black probe of the multimeter to ground and the red probe to the 5V interface. Then connect the red probe to the four-pin auxiliary CPU power interface (set the multimeter to continuity/buzzer mode). If the multimeter beeps, the circuit is normal.
Next, place the black probe on a pin of the CPU auxiliary power interface, and slide the red probe across the pins of the U-chip next to the CPU. If a short beep occurs, stop immediately. The corresponding pin is the CPU 5V power supply pin (this U-chip is the power management chip).
Then check the two pairs of MOSFETs next to the CPU. MOSFETs should not show continuity between all three pins. If all three pins are conducting with each other, the MOSFET is damaged and must be replaced.
Finally, measure the capacitors and resistors around the CPU socket. If power is present, the CPU power supply circuit is generally normal. Common failure points in the CPU circuit include MOSFETs, the power management chip, and capacitors.
Overall Motherboard Testing Procedure
Insert the diagnostic card and install components step by step: first the CPU, then memory, and finally the discrete graphics card. The diagnostic code usually starts at 00 or FF, and then progresses to codes such as 01, C1, 24, 25, 26, etc.
