I had my PC totally powered off like I usually do, but when I tried to turn it on later that night, it wouldn't respond at all—no power, no fans, nothing. I took it in for repairs, and the technician was able to power it on without any issues at his shop. He performed some maintenance, replaced the power cable, and sent me on my way. However, when I got home, the same problem occurred. I decided to switch out the power supply unit (PSU) to an MSI MAG a550BN, and it worked fine initially. I used it without problems, but after turning it off, it wouldn't turn on again. I'm really stressed and uncertain about what's causing this issue. Here's my setup:
- Motherboard: Gigabyte B550M DS3H
- CPU: Ryzen 5 5600
- GPU: RX580 2048SP
- RAM: 16GB (8GBx2) 3200MHz DDR4 XPG
Any advice would be greatly appreciated!

Have you removed all USB devices like your mouse and keyboard before trying to boot it again? Sometimes peripherals can cause boot issues.
Just a simple thought—are you sure the power outlet is switched on? If you used a different plug in the shop, it might be worth checking that all fuses are good and that other devices work in your home socket.
Have you tried plugging your PC into a different outlet? If the issue only occurs at home, it could be a problem with your home's power supply rather than the PC itself.
You could try unplugging everything, removing the motherboard battery, and pressing the power button a bunch of times to release any residual charge. It might also help to check if the tech could power the PC off and on multiple times without issues.
This might sound silly, but could the monitor be the issue? Are you sure there's no display issue? You can try turning it on without any connections to rule that out.
