I tried again and changed the CMOS battery. When I activated the power button on the PSU and connected it to the outlet, I detected some static noise coming from it. This suggests the PSU might not be the issue since it powers on but doesn’t fully activate the PC. I double-checked all cables and confirmed they were secure. It seems the problem isn’t with the motherboard, as it worked before I turned off the PC. Is this related to the PSU or another component?
Consider switching to a different power supply unit, it's tough to determine whether the issue is with the motherboard or the PSU, but the PSU looks more probable. Starting with a replacement is a good idea, as it's simpler to fix the PSU too.
