Minisforum NAB6 HardDrive/Fan issue

HI,

I have a minisforum nab6 I bought from Amazon last August. The first one that arrived died within hours and the replacement has been "ok" since, few reboots, few blue screens, nothing that I couldnt fix myself

The other day it refused to power on, I turn on the power, the fan goes crazy but no blue light. Did all the usual reseat the ram, cmos reset etc, nothing.

I disconnected the NVME drive and it then booted into the bios. Reconnected the drive, fan goes crazy no light. You would think that its the drive thats the issue but I left the nvme drive disconnected and connected a 2.5" SSD to another part of the board, turn it on and again no blue light and just the fan going crazy until I power it off.

Any ideas? To me it would seem to be the board but then would it boot into the bios?

Minisforum support are being less than helpful, suggesting I just buy myself a new nvme drive and they'll re-imburse 50%, on a product less than a year old!

Any suggestions would be welcomed warmly!
