Hello!
I got new CPU today I7-9700K, before that i used I5-7500. When i try to start my pc lights turn on and fans and after 1s shuts down. I checked if my RAM is placed good at it was, and i reseted my BIOS settings to default. Does anyone know how to fix this?
I'm using Mortar Artic H270M motherboard.

I don't think it supports anything newer than 7xxx cpus

you should either upgrade your motherboard too or return the cpu.
