Question Freshly built PC always restarts

[RebelTrankill]

Hi,

I've built quite a nice rig but there's a problem....it always restarts.

It could stay in the BIOS stable for days, the temperature never gets over 30 degrees, the power supply works. two additionals fans working, but everytime it gets to Windows, it restarts within 5 to 20 minutes.

I've deactivated all things that makes Windows 10 restarts automatically but I always get to the same point.

Any clues?

Specs would help?

Hi,

MSI MPG Z390
CD burner
1 WD 500gb SSD
1 WD Black 2TB
32g RAM Corsair DDR4 3000

No graphic card included but I've modified the option in the BIOS to not have the computer to try to run on a physical graphic card

I'm now in safe mode and it doesn't do it :/
