A lot of things. We don't need the ram, GPU or drives for a power up test.
We don't need a case either.
As to connections, we only need one. The Power On connection.
I've just built a pc, but it won't turn on. The only thing that lights up when I plug it into the wall is an LED in the front IO. This LED also stays on for a while after turning the PSU off again... Besides that nothing happens at all when I press the power button: no fans, ... nothing, it's a lifeless pc.
I've tested other ram slots, replugged the 8 pin and 24pin connectors, an other psu, double checked the front io connections...
There are also no lights lighting up on the motherboard. Like it gets no power? (Still the pwr LED lights up in the front as soon as the pc is plugged in the wall)
Could it be a bad powercord or a dead motherboard out of the box?
I dont know what to do anymore...
MSI b150 pc mate
Core i5 7500
Crucial lpx ddr4 2133 ram (2x4)
Psu: Seasonic 520w psu
Gtx 1060 3G
