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.
