I have the corsair lighting node core which came with my case, the 220t. This problem happened to me and I did a soft reset, deleting all applications on my pc, and the problem was still there. Like you guys, I also did a lot of driver uninstalling and reinstalling in the device manager, but the problem is still here. My lighting node core doesn't show up in the icue software and continues to only stay on the hardware lighting, which I set to pink. But if quickly flashes blue and there's nothing I can do about it. In my windows 10 settings under Bluetooth and other devices, it says Corasir lighting Node Core, and under it says driver error. My ram still works fine however. Not sure how to fix it tho.
