I have an
ASRock Fatal1ty Z370 Gaming K6 motherboard which is a quite recent board. While I was using my computer, everything shut down rapidly. At first, I thought it was a power blackout in the house but the other appliances seemed to work. I then realised that the computer was refusing to boot up.
I thought that it was the power supply but after removing it, I was able to successfully power on an older computer that drew less power. The power supply is a 750W
Corsair RM750X. I disconnected all hard drives, M.2 SSDs and memory DIMMs and decided to test the motherboard with the CPU and power supply separately. I also used a working 450W power supply to test the motherboard but unfortunately, the same results were evident. A video of the problem is available here.
As soon as I flick the switch on the power supply, the motherboard lights up briefly before dying again. The on-board power button also refuses to work. If it may help, the BIOS was updated a week earlier but updated perfectly fine since the computer was being used normally and functioning normally before this incident occurred. Any help would be greatly appreciated.
