Pc not starting and making popping sound through speaker

[Nathanc]

Hi guys my pc randomly shut down on Friday and then again about two hours later but refused to turn back on, when I plugged the power in the pc would do nothing however through my speakers i could hear what sounded like a popping of power turning on and off every second. I figured it sounded like a boot loop and tried removing ram to check one was not damaged and removing the graphics card even tried removing the CPU but still no start up. I bought a new PSU incase that was the problem yet the same issue still remains, any help or tips would be welcomed as I assume now it must be motherboard related, thanks.

since you have replaced the PSU (and providing everything was reconnected properly) that really only leaves the motherboard as you have already done what one would normally expect with the CPU, RAM and graphics card..
