Must clear CMOS every time computer reboots

[jonathanweiss2003]

Every time I put my computer to sleep for more than 10 or so hours when I boot it up the fans spin up for 5 seconds and the lights come on but then it turns off. It keeps on turning off and on until I unplug it. To get it to start working again I need to clear the CMOS. I have done no overclocking.
It is a new build running:

Motherboard: MSI Z370 PC Pro
CPU: i7 - 8700k
Cooler: Be quiet! Shadow Rock Slim
Graphics Card: GTX 1080 Strix
Ram: 16 GB of dominator platinum (all is registering)
Power Supply: Corsair HX 750W
Storage:
Corsair Force M.2 480 gb (boot drive)
Asus CD rom
Seagate hard drive


Pls help

Have you tried updating the Bios?

No I have not. I don’t know how because no update is out

I tried that. I had a successful update and I’m not sure if it fixed the problem. (Haven’t slept it yet because I have some work to do today)
