the game minimized while playing on the gamepad

Such a poser playing on the gamepad the Logitech f310 game (any) occur to minimize to the desktop, keypad-mouse everything is fine.
removed the unnecessary services via the msconfig and in the startup too much, 1 day helped, then again.
I noticed that earlier folded after a long session in-game minute from 20-so hours of the game, now collapses right at the beginning within 10-15 minutes
