sometimes your pc requires a sacrifice lol Does it work now?

is your render distance set to 48 chunks? Also sometimes for weird reasons minecraft will try to us the integrated graphics instead of the graphics card. This happened to me once.

Based on what you have tried, I'm assuming this is a motherboard issue. If you have another one, you could try and swap it out maybe? Is there any beeping after it turns off? Or does it say anything during post after you turn it back on?
