Hi,
I have a friend whose PC is having some unusual starting issues.
It starts all the time at my house, in any power socket, but at his house, it does not start at all (regardless of the power socket).
Motherboard lights come on at both our houses when plugged in, but when the power button is pressed on the PC case it does not start at his house.
The PC used to start just fine at his house, but now it doesn't start at all (with the exception of the motherboard lights when plugged in)

The powersupply is Corsair CX450, it has no switch on it to toggle between power voltages.
CPU - Ryzen 3 1200
GPU - MSI 1050ti
Motherboard - Asus ROG STRIX B350-F Gaming

We tried starting the PC without and with a monitor connected at each house, doesn't make a difference.

Any suggestions?
Thanks
