I have an ASRock Fatal1ty Z370 Gaming K6 motherboard which is a quite recent board. While I was using my computer, everyone 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. A video of the problem is available [URL=https://drive.google.com/open?id=1ASdFauVlQ85Elep4D0E96msVYf7qJOLS]here[/URL].
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.

Have you cleared the CMOS and tried with one stick of memory and in different slots?
Disconnect everything except one stick of memory, PSU, CPU, and hook up the monitor to the onboard GPU.

I have tried that. Still the same problem. As soon as I connect the PSU, the lights turn on and then just die again. Power button doesn't turn on the system, with or without a CPU and memory. I can hear this buzzing sound from the sound card, where it says Creative Sound Blaster below the IO. I don't know what that means.

Are you trying to turn it on with the power button on the board or the button on the case? Try the one on the board.
