Question PC shutdown randomly, doesn't turn on

[mrlou]

Hi,

one mont old pc that I built. Yesterday while gaming pc randomly shutdown, doesn't turn on. I tested the power cables, gpu, ram, psu, and cmos battery - these are ok. When you press the power button AIO-pump rgb light flashes and fans spins for second. Here is a video what happens when power button is pressed -->

full system spec? include brand and model of the psu

check cpu/gpu temp?

only thing I can see is you left cable hanging around the motherboard
