The other day my PC was working fine, then I left it for some time and when I came back it was on sleep mode.
I tried pressing a random button on keyboard to wake it, but no response.
Pressed reset and no response, I repluged it to the outlet and when I pressed the power button I could hear the fans wiggle and turn off again, the RAM rgb turns on and it stays like that.
The PC is pretty new I had for about 2 months now. That means it is all connected as should be.
I checked that everything is on place, tried different outlet, and a different cable. Restarted the CMOS.
Any ideas?

Specs:
Motherboard: z390 aorus elite
CPU: i7 9700k
GPU: nvidia gtx 1080ti
PSU: Antec hcg 850m
RAM: corsair vengeance pro 2×16 gb

Edit:
I left it off for the night, in the morning I tried to turn it on again, it was making noises as if it tries to start for couple times, then it was finally working normaly, after couple minutes went back to the state I mentioned above.
