Windows and Battlefield 3 "alt-tabbing" itself

[Sanaudrius]

For some reason for the past couple of weeks My computer keeps "alt-tabbing" without me clicking the buttons and this is espically annoying when it comes to playing my games. Whenever. I play Battlefield 3 at a random moment it justs alt-tab's itself back to the desktop. And when I play in Windowed Mode the game stops and the Windows Mouse Cursor appears, I click once and i return back to my game but it happens again at a random moment. Here's what I know so far:
1.) It's not Sticky Keys because I haven't got it enabled.
2.) I think it's a WINDOWS problem becuase I was playing the Witcher 2 for a half hour without the game alt-tabbing.
3.) The main issue that I find with this is Battlefield 3, if someone can figure out this problem that's all i ask.

Thx

It's a process that popping up taking priority over your games.
You have to find which one it is in your task manager
