When playing for about 10-15 minutes I freeze. Not just Minecraft, my entire computer stops responding, requiring a hard reboot. A few things to note:

1. I am playing multiplayer in all of these instances. (Haven't tested this issue with Singleplayer worlds, will update this when I get the time to test)

2. I have some major background processes running like Steam, Discord, etc. Perhaps these things starting up while I'm playing is creating problems? I don't know, I'm not the expert.

Let me know if there's anything I can do to help.
