[SOLVED] Motherboard LED turns on but nothing else

[PapaGavGav]

So I have just put together everything together for my new gaming pc, apart from the gpu but I don't think thats the issue. When I turned on my computer to test if everything is working,the only thing that happened was that the motherboard LED turned on. Nothing else turned on in the PC. I don't know what to do, any help?

Update: I touched a screw driver to the front panel connectors and the system turned on. But I still don't know the issue...

How have you connected the case fans/hub to power supply/motherboard?
Edit: it could be a broken power switch.

If absolutely nothing else is happening then doublecheck all cable connections.

Ensure that all are fully and firmly seated. That can be problematic with new connections - very tight and generally no one wants to or should need to force the connection.

Do you have the motherboard's User Guide?

Review the User Guide and watch for some step or action that may have been overlooked.

BIOS?
