My pc starts up (fans spin, lights are on) and then closes after a few seconds, and then starts up again normally and successfully booting to windows

This only happens when i first start the computer after hours of it being turned off and unplugged. It starts up then off and then on again normally. 

 

The sequence does not happen when I turn off and then on the computer that has already booted to windows. It only happens when i turn the computer on after it being off for hours. So usually the start of the day.

 

Specs:

Cpu - amd ryzen 5 1600af

Gpu - asus gtx 750ti

Mobo - asus prime b450 plus

Psu- thermaltake litepower 550watt

Case - antec dp501

Aio cooler - corsair h80i v2

 

- Rear exhaust fan is connected to chassis fan header 1

- Aio cooler is connected to cpu fan header

- one top exhaust fan connected to chassis fan header 2

- 3 fans (1 rgb) is connected to chassis fan header 3 via fan splitter

Oddly sounds like the CMOS battery maybe? Sounds like it's trying to do retraining and not maintaining settings.
