Motherboard won’t power up unless I push it down on to the crypto mining chassis

[JamesP88]

Hello,

Sorry for the long title.

I am having a rather weird issue which I assume has something to do with grounding?

I’m running a mining rig with a metal chassis. The system will not power up, unless I push quite firmly down on the motherboard where the main mobo power connector is and then it fires up and works until I let go.

I understand this is not good practise to do but does this explain what is causing the problem? I see sparks below the power connector underneath the mobo as it touches the chassis and everything powers up. Then I let go and it stops working.

Any ideas guys?

Kind Regards,
James

Here are some pictures. The rig, a picture of the main power connection and underneath if those silver pins touch the black metal chassis it works.
