So i got this issue again 2 times in the past, the first one was around 3 months ago the 2nd around a month ago and i just got it again. The PC just "shuts down" out of nowhere, the monitors turn black, all the rgb peripherals i have turn off, but the fans keep spinning. Holding down the power button in order to do a force shutdown didn't do anything, i had to turn off the psu in order to power off the system, what could be the cause of this?
