[SOLVED] Problem with RGB

[TTLES]

I'm having a problem with RGB on my MAXIMUS IX EXTREME motherboard.
When a system is off, my rgb lighting is normally working, but when i press power button, about a half of a second later all rgb turns off.
In BIOS i have RGB lighting turned on, and in sleep, hibernate too. (I'm using the latest BIOS).
I've tried, different OS's, unplugging disks and all PCI-E cards, reseting BIOS but nothing helped?
Any help?
Thanks!

there can be multiple LED options in the BIOS.
if there is a "stealth" mode activated by default it can cause this type of scenario.

what are you using to control LED options within the OS?
