Black screen when you minimize games with source

Games that work on source not removed. Or rather when minimize the game a black screen appears. Despite the fact that the system does not hang, for example can play music menu. In csgo this topic is that the game minimizes when Alt+tab black screen. Helps only reboot. Manager is not called, or I don't see it on a black screen :kofe. I read that the theme of the game sourse for fuckin ' with me so not just me. For test downloaded team fortress 2. There the matter a little more. Game altabella to a black screen, and when re-Alt+tab the game back included. To test does not hang if the system tried to alternates on a black screen (supposedly the desktop) and click win+right+enter' comp was off and it turned off :idiot. Who faced such problem and how solved? I have a similar situation was when I played in mk9 and there at the entrance to the game was the sound but had a black screen. I read that the monitor allegedly doesn't see something or to the wrong connector plugged in the cord to the graphics card. Helped win+p and choose the items at a time.
