Z790 Formula RGB stopped working

Level 7


Just installed Z790 Formula and i9 14900k and everything was working fine. Bios was properly updated too.

All of a sudden, RGB stopped working yet MB screen is working 

The MB had a strange white powder over RAM slots and some stains of dried liquid on the back when I opened the sealed box. A technician cleaned everything up to test it, and that happened with RGB.

MB is not recognised by Armoury Crane though yet the pc is working fine.

Any ideas before returning in?

Hello, @A73SSANDRO 

Based on your description, everything was normal at the beginning of the assembly.
Could you specify what software or hardware changes occurred before the RGB lighting issue arose? Is it the RGB on the motherboard, or is it the RGB on other accessories that are not lighting up correctly? For example, the fans.
Meanwhile, may I ask if the technician you contacted is ASUS officially assigned, or did they come from the dealer?
Do you have any photos of the white powder and dried liquid?
If you've recently made the purchase and have any concerns or issues, we recommend reaching out to the dealer promptly for assistance with returns or exchanges.

Thank you.

Due to the ongoing regional holidays, my responses may be slightly delayed.
Thank you in advance for your patience.‌‌‌‌ 🙂
