Windows Rebooting Randomly

[Joel_60]

Hello,

I bought a new motherboard and memory RAM to upgrade my older parts. I put everything together but I didn't format my hard drive with Windows 10 already installed on it, since it will recognize all the new hardware automatically. Everything looks fine, except it keeps rebooting randomly. It was bad idea what I did about not perform a new installation or do you think this is hardware related?

what are the parts in your PC?

random restarts without errors doesn't sound like windows to me. Well, it could be running windows update but it would be obvious if it were them
