Question PC randomly shuts down but fans keep spinning and light are on

Sep 27, 2020
So sometimes when I turn on PC everything starts for couple of seconds and then mouse and keyboard light turn off and nothing displays on monitor but fans keep spinning and light on case are on or PC can work for hour just fine and then everything freezes and then keyboard and mouse turn off and there is no display but fans keep spinning. When that happens I have to force restart and then everything works fine for some time(sometimes even weeks). I don't know if it has anything to do with it but sometimes when my PC turn on it skips the part when windows displays name of user and it justs loads to desktop. I installed latest drivers for GPU. CPU and GPU temps seem to be fine when it happens so i don't think overheating is a issue.
CPU: AMD Ryzen 5 2600
Motherboard: Gigabyte B350M DS3H
RAM:Viper 2x8 GB DDR4 3200MHz
