Since last patch Computer shuts down

[Xeonrf]

Since this last patch the computer will shut down ramdomly while playing Civ4 BTS. Can't figure out why, it wasn't doing this before. This isn't a lockup, just a complete shutdown to where I have to restart.

Hope I did the attachment of the dxdiag fileView attachment DxDiag.txt

Anyone have any ideas or suggestions?

Is there an error in the windows event log from when this happens?

Nope just shuts down. Although I took the side of the case off and it hasn't done it since so perhaps its a heat issue.
