Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - Technical Issues Consistent Black Screen Crashes

I bought the game a few days ago and really want to play it but,

The game is causing my computer to crash to a black screen every time I play. I can't get past the first orc fight without my computer shutting off and the sound looping.

I have:
updated all my drivers
Uninstalled and reinstalled the game
Checked the integrity of the game cache
Run a memory diagnostic on my RAM

none of which solved the problem or helped me diagnose the problem

I don't know what else I can try, any help would be most welcome
