There may be an issue with the motherboard.
I initially believed I purchased a dead power supply unit, so I swapped it out, but my computer still won't turn on. This might be because the motherboard is faulty. Are there any methods to verify this issue? When the system starts up, absolutely nothing happens.
Check if all connections are secure. Observe any reactions when you activate the power switch—do fans spin, lights flicker, or the power unit engage? If a CPU failed, the motherboard would turn on but the system wouldn't boot. The same applies to RAM or in certain scenarios with your graphics card.
Typically, unless there’s a major failure with the motherboard, you might still manage to supply power to it, even if it’s not fully functional. There’s a distinction between completely dead and mostly operational devices.
This appears to be a fresh installation. Verify your power supply is turned on. I encountered this issue before with a system stored away.
I've checked several times and still no result, but your PSU seems to function properly—could it be the CPU?
No activity detected and the PSU is functioning, but it doesn’t indicate a failing CPU. The motherboard appears to be inactive.
Verify the header connections between the board and the power switch. Ensure the switch is properly seated. You may need to manually jump or short the switch pins to confirm the issue isn't with the switch. If the board fails to receive the signal, the PSU won’t get the necessary power activation signal.
