Just to confirm, switching the power supply won't help you. It's meant to check if the supply works by simply turning it on. Your setup is correct—it's not intended to diagnose why the computer shuts down. Also, ensure the supply is placed outside the case or unplugged during the jumper test. If it's a thermal cutoff, it should display the CPU temperature in BIOS. What reading do you see at that moment?
The CPU appears to stay idle near 25°C, but we couldn’t measure the GPU temperature. Since the power supply was taken off, we won’t be able to check the GPU’s heat for now. It typically ranges between 40-65°C based on the workload it handles.
These readings are typical, indicating no overheating problem. The GPU displays temperatures only in Windows, not in the BIOS.
That works fine. Your dad is removing the power supply from his PC now, so we can check whether the issue lies with the power supply instead of the motherboard.
