heathersm1992 I'd like to read the dxdiag, so please attach it to a reply here. Most of the issues I see in dxdiags aren't flagged as actual problems by the dxdiag process itself.
If your GPU is on its way out, failing but not yet entirely failed, this is one way that could present itself. But your description could point to another, more fixable issue as well.
Last night I decided to start completely over, deleted my saves and mods and it went black during CAS and also during build mode so it's doing it all the time now. I hope my GPU isn't going out :(
