Something is running that keeps making my active windows inactive : The window will turn gray and I have to click back on it to use it. It's happening now every 20 seconds. Annoying as hell. If I have Media Player fullscreened, it'll keep putting back to window. If im playing a game in fullscreen, it minimizes it. I'm getting seriously annoyed here.

Yeah.. take care of the most plausible reasons first. If all else fails... System Restore to a known good state.
