My desktop computer is malfunctioning during starting up. I turn it on, and after about 3 seconds it turns off for a second then starts back up again. It does this process mutliple times before it starts up for real, and brings me to windows. Also, very rarely, but sometimes my computer randomly shuts down. This is not a temperature, because I monitor the temperature very closely and this happens when I am on a web browser, not gaming.
I'm using 16g ram with an Nvidia Titan V, Ryzen 1800x. All of that in a mini-itx case. The motherboard I am using is the Asrock Fatal1ty X370 Mini-ITX board.

How can I fix this problem?
Thanks so much!
