Game locks up computer, requiring reset

[Voidkissed]

Update: Switching to dx9 after doing a clean reinstall seems to have solved the issue, which is not ideal but if it works, it works. Will update if it continues to cause trouble.

I've been having some similar issues and DX9 seemed to work for a bit - until it flat out crashed and freaked out my gpu and laptop for almost a whole 24 hours until I managed to remedy it. And as is it still only lets me play for a limited amount of time before DX9 dies too. And similarly, this is the only game or anything on my computer having problems.
I'm hoping it works for you of course, just, wanted to give you a heads up in case it isn't a solid fix (hopefully we both can have this remedied!)
