PC randomly shuts down or gets black screen

I've been having this issue for a while, my PC will either randomly shut off usually when I'm playing games, I sometime get a black screen on both my monitors that doesn't allow me to press any button to do anything, this sometimes happens after my PC
randomly shuts down when I log in or when I'm playing a game, I know it's not a overheating issue.

Billion,

I have tried following the steps to resolve the issue; but, after opening properties, there is not a Security Tab featured. The only available Tabs are General, Hardware, Sharing, Customize & Recording.

PC shuts down while playing video games

Hello. I recently started a minecraft server through a hosting website. Ever since then, my PC will randomly shut down while I’m playing after maybe 10 minutes. I don’t have this issue playing any other game or using any other programs for that matter.
I’m not running a Java server off my PC, it’s ran through the websites servers.
