Hi, some days I'm having some problems with the lighting of my PC, the following components:
- Asus Aura Pro Gaming 970
- AMD FX-9370 (Unlocked)
- Nvidia GTX 970 4 GB GDDR5 Zotac AMP! Edition
- Samsung SSD 830
- WDC HDD 500GB
- Corsair Vengeance 8GB (2x4) 1600MHz
- Coolermaster sink in liquid seidon 120V For CPU
- Corsair Power supply 750 Watt Modular Series CXM ATX 2.3 V

The only changes I made in the BIOS has been moving the ratio of the CPU 20.

The problem?
On certain days the PC starts without problems, in others after 5 or more attempts, the beeps will vary from 4 to 2 to 3.
I am going crazy..
 

I tried changing disabling the fastboot from the BIOS but the problem still here, I've Windows 7.

I find this: https://www.asus.com/support/faq/1029959 but..the beeps varies
