Windows 7 odd issue with all full screen games

#1
I'm having an odd issue with my windows 7 install, build 7077. In the past few days whenever I play a full screen game it works fine for about 15-20 minutes, and then will minimize, showing my desktop for a few seconds, before popping back into the game. I haven't changed any settings in windows recently, and have had the new build installed for a couple of weeks with no issues. Anyone else having this same problem?
