Win7 Blue Screen only when play BC2

I am running Windows 7 and frequently get a screen freeze while playing Battlefield Vietnam II or Battlefield II only. This happens quite often and I see no patterns except for these 2 games. I have updated my video drivers, my temperature is cool. I am so frustrated. This is a relatively new computer.
I have an NVIDIA GeForce GTS 250 (Prerelease - WDDM 1.1)
