Computer stops responding

[PapaTDaddy]

Hey guys! 
sometimes my computer will randomly shut off both monitors and the pc lights will stop responding. The whole computer stops responding and the hard drive light stops flashing. I have to hard restart it using the power button. Does anyone know what would cause this? 

CPU: I9-10900k
RAM: Corsair Vengeance Pro (3200 mhz) 32gb
GPU: Rx 5700xt
Motherboard: ROG Maximus Hero XII
PSU: Corsair RM850x 80+ Gold

Does it happen under load (e.g. gaming) or when being lightly used? Or both? Any overclocks applied?

It happens under load and when idle. I had an overlock on the cpu but I took it off and I still get it. It sounds like a ram problem to me but I'm not for sure.

Memtest would be able to tell you that. Have you run that yet?
