Windows 10: PC freeze indefinitly after closing out of/alt + echap, alt + tab, or windows +d

When I am playing a demanding video game, if i alt + echap or other shortcut my screen freeze for indefinite time the first time it happened I waited 1h and the screen was still frozen. It happens not every time i alt + echap of the game but like 1 chance in 5 and when it happens it won't happen until I shutdown the pc.When the pc is frozen the game is still running I can hear the sound of it and can hear and speak to my friend on discord, the only thing who isn't freeze is my mouse, but I can't click and alt + f4 or crtl + shift + echap don't work. I tried crtl + windows + shift + b I hea

alt + tab not working

Just found a really cool way to make alt+tab INSTANT!!!

In the launch options write the following: -windowed -noborder





This play exactly the same as fullscreen but now you dont have to wait 30 f*@!ing seconds to alt+tab back in!

Also you don't get the little purple/black checkered effect (only in Source games) from alt+tabbing in fullscreen.

 

alt + tab not working

i always just use the windows key to get back to the desktop [pops up the start dealy, doesn't need anything to alt+tab to]
