Question Motherboard lights are on, all USB ports are working but the PC won't start.

[Kahnwald]

Hello,
I hope you all are doing fine.

Today I was cleaning my PC and after that I built everything together as always, the 24 pin connector, the 8 pin and all of that. Everything seems in the right place, but the power button just don't start the PC. All of the USB ports (front and back) charges my phone and all led's of the motherboard are active.

What I've tried so far:

• - Double checked the front panel connections and it's ok
• - Tried starting with the screwdriver and didn't work.
• - Tried all ram slots
• - Swapped the reset/power sw connectors, didn't work either.
• - Restarted CMOS

I don't know what else to do, what could it be?

Tested the GPU and RAM in another PC and they are working fine. Anyone got any ideas? I am about to test CPU. If every USB port is working then I can rule out the Mobo, right?

For anybody to help, you need to list all the components (make and model) .

Right, my bad. Here are the components:

Motherboard: Asus Rog Strix B350-F Gaming
CPU: Ryzen 7 1700
RAM: Crucial Ballistix 8GB
GPU: Asus Dual 1050ti 4GB
PSU: EVGA 600W 80P White

The RAM, GPU, CPU I've tested in another computer and are working fine.
Mobo leds are active and all USB ports have energy (charges phone).
