I have stumbled on a few of those old MSI threads, sounds like it was a nightmare. Thanks for the suggestion though, I’ll look in to the Nu-Link tool . It might be a bit above my technical competence but I’m up for a challenge, this is really eating away at me haha.

I must just be one of the lucky ones then. I’ve read people having similar issues with ASUS boards for years, but there doesn’t seem to be any real common threads outside of just the general symptoms.

Thanks for the reply and the insight. There’s no ASUS USB device from the looks of it, so it sounds like a firmware issue indeed then. I’ve tried looking before, but I can’t find any first-party solution from ASUS to update LED firmware. Am I pretty much SOL you think?
