Why does my ASUS X570i Gaming motherboard go black full speed CPU fan in the middle of the night? 

 

I have to reset the power switch on the power supply to get it to turn off as the power button does nothing.

 

Thanks

 

I have my RAM at 3200/1600 infinity fabric & IMC all auto voltages even on the CPU 1.4V or so is what auto sets it hits 75C possibly max @ 4.5GHZ.

What do you mean go black? The system has hung and then the fan goes full speed?

Yes but I just updated my bios and tuned some settings & also realizing we have constant power outages here so I think it was a combination of the power outages and the 2022 bios version i was on now im on 2024 bios and its better even know the system doesn't work right now as my vega gpu has failed again after running it at 96C hotspot for 2 min it stopped working at stock bios values undervolted with a 50% higher tdp from 260W, it only used 288W and everything other than the hotspot was around 48C.

Fingers crossed it was just a glitch, sounds like you have sorted it.
