In Games Crash With Invisible Window (Dell Inspiron 15 5570)

Hey there, when i try to play lots of my games, for example my most recent attempt: Dota 2, I can manage to load up the game but when i actually get to the game-play, I am forcefully brought back to the desktop, but the game continues to run. The game runs in the background and my task bar at the bottom of the screen, but the window is invisible as in the cursor appears but tabbing out or forcefully closing does not do anything, so i can not do anything on my laptop, even task manger is blocked behind this 'invisible window' so i have to log out. I can play lots of games without problems before, I bought my laptop 2 years ago and everything is fine, the drivers, bios, graphic cards are all update, I played every games in the lowest graphics available and it still occurs.
