Hi all,

Just got a new build and I'm trying to breadboard it, however it's not getting past POST.

I've got the CPU installed, cooler attached and plugged in, CPU power plugged in, and the motherboard power in.

When I short the power headers the fan starts spinning, however that's it - no beeps from the speaker, no display (I'm using onboard VGA).

Here's the specs:
Motherboard: GIGABYTE AB350M Gaming 3
CPU: AMD Ryzen 5 2400G
RAM: Corsair Vengeance DDR4 2x8GB
PSU: Corsair VS550

I've tried using the HDMI port, only one stick of RAM, and resetting the CMOS.

Any suggestions would be much appreciated!
