  • no new hardware was installed
  • no BIOS flashed

Observations/things I tried:
  • QFlash + "clean CMOS" buttons (located on the back IO panel) are blinking automatically after turning on the PSU. I tried searching the manual and internet for what this means but didn't find anything.
  • After turning on the PSU and pressing the case power button, nothing happens.
  • I unplugged the PSU cables (24-pin, EPS and etc) and replugged them.
  • I unplugged all the PSU cables again but this time, I only connected the 24-pin and EPS cables.
  • PSU turns on by itself by shorting the PS-ON pin to ground method. I've checked the voltages using a meter and they are correct.
The setup is using water-cooling so swapping/moving parts is not that easy without dismantling.

Thanks for help.

So the rig was running normally up to what point? Did you do anything to the rig out of the ordinary? Moved it? Flash/updated the bios?

You're not giving us much info aside from "doesn't turn on"
 
So was it running and then just turned off(pops / smoke?) / did you have it powered off and then it just wouldn't start.. have you checked the debug LED for codes? (appendix 6-3 of the user manual for this board)
