Game turning monitor off and then freezes

@abbytheepic Hmmm, this sounds like a graphics card crash. One thing that might help -but no guarantees -  is to perform a clean reinstall of your graphics drivers. That is removing them fully then installing a clean set. 

A few years ago I had similar "weirdness" on my machine until I took this step, turns out I had a bad driver that wasn't getting detected even when I updated my drivers as normal. 

Anyway, I hope this helps, but as crin says, it might be down to your machine too.
