Something like that, but it started when i tried to change RGB Fusion and RAM speed directly from BIOS, as RAM is on 2400Mhz RN, and i tried it with XMP profile 1 on 2933Mhz. After that i save and exit and it didn't post. When i normaly turn down PC and turn it again it starts again, but when i leave it for few minutes, it wont start.
Currently it is working with last CMOS reset, without touching BIOS settings at all.
