My computer has been functioning well for about five years until today. When I tried to power it up, nothing happened—no lights, no fans, and no electricity at all. There was no power outage overnight; I didn’t do anything unusual except hibernate normally. Eventually, I disconnected everything except the motherboard and power supply. The CPU, RAM, speakers, and other components were removed. I swapped the PSU, but it still wouldn’t turn on. If I connect the pins 4 and 5 on the PSU, both start up and the motherboard LEDs illuminate. When I reconnect some devices, the CPU, case fans, and GPU begin to spin, but the speaker doesn’t sound and there’s no display output or power to USB ports. I suspect the main board is dead, since even without a CPU, the PSU should have powered it on. The system runs a Ryzen 5 2600 GA-AX370M-DS3H with 1060 and 750 Ti 500W/650W PSUs.

These budget gigabyte boards seem to be of poor quality and might not last long. After more than four years of use, such components often fail. What’s the purpose of having two power supplies?

x370 seems likely to be gone. A failed CPU is extremely uncommon; it's almost impossible to destroy physically.

If you were managing the 500W power supply... But welcome to hibernate, who advised you to use it and why? (except for damaging parts). This isn't a laptop, you're not preserving energy or any power returning from deep sleep. And yes, every part in a PC has an age limit before it fails, so turn it off when you rest.

Sure, I can attempt that. Avoid the A520 and B550 models—they don’t have Zen+ support.
