I have Aura mobo and it defaults to rainbow vomit every time it's powered off or on.
I'd like to know if there's a fix out there for this.
I found this:
"Hey guys for everyone who's still interested... I ACTUALLY HAVE A SOLUTION!!!!
it took me several hours to figure this out, but it was fairly important, since this is a show PC...
Windows is messing with the sys files on boot for some reason, and you can prevent this by unchecking the fastboot option in Windows 10.
To do this, press win+x
In the power Options chose what the power buttons do
Show unavailable options
Disable fast startup
To do this, your boot settings have to be UEFI and the os has to have control over some stuff I can't remember exactly what I checked tho... If you have any questions, I'll try to answer them "
But this don't work for me. How can I set boot settings to UEFI? I have Z-370F Gaming.
