PC won't boot

[rorehh]

Hi Guys!

I have a problem with my system, it won’t power up at all, I do hope you can help me.

The components are:
- Motherboard: Gigabyte ga-ab350-Gaming 3 ATX
- RAM: Ballistix Sport LT DDR4 2666 UDIMM (2x 8gb) Modelnumber: BLS2C8G4D26BFSEK
- CPU: Ryzen 5 1600x
- CPU Cooler: MSI Core Frozr l
- GPU: Zotac GeForce GTX 1060 1506 zt-p10600 a-10L 6 GB (mini)
- HDD: Samsung MZ-N5E500BW 850 EVO Internal SSD, 500 GB, SATA III, 6 GB/s, M.2
- PSU: Seasonic Prime Focus modular (80 + Gold) 550 watt
- Case: Phanteks Eclipse p400S MIDI-Tower, tempered Glass

Things I’ve tried:

- I have checked the PSU, it works 100%.
- Connected the ‘blue USB3 front panel cable’ and it actually charges my phone via the Front USB slot. So there seems to be power.
- Tried using only 1 RAM module , and tried different slots.
- Tried without HDD
- Tried without GPU

Whenever I push the Power Button on the case. The PC will not start at all. No beeps, no spinning of fans, No LED , nothing.

Note: I have checked the RAM support list for the motherboard online and the ‘Ballistix Sport LT DDR4 2666 UDIMM (2x 8gb) Modelnumber: BLS2C8G4D26BFSEK’ does not seem to be on the list.
Could it be a compatibility issue? Unfortunately I do not have any spares or different type of Memory laying around.

Any help is appreciated.

Kind regards,

Discounting possibility that some part is DOA there must be some connection you missed or mounted something wrong way. There's really no great secrets, you plug everything in right and mount it properly and it should at least power up.
