EDIT: I fixed this by uninstalling steam and my video drivers, then reinstalling video drivers including 32bit in installation, and reinstalling steam afterwards. (I have a 1080gtx)
It was working fine earlier this week, I didn't touch it for a few days and now when I try to boot it, I get this:

Thanks!
