No RAM or Front fans are showing up on devices

Hi all,

All of a sudden, my Corsair vegenace pro and my 3 front fans connected to the lightning node cannot be controlled via SignalRGB. The node shows up in signal rgb as device, but if i add my fans i can’t control the rgb for them, and my rams don’t even show up anymore. Days ago everything worked, i did not move the pc nor the cables. I don’t have installed any icue or other software, just Signal RGB.

Can someone help me? Thanks
