Okay , so few days ago I updated my windows 8.1 to 10, and I installed all drivers and stuff, but there is one problem , when I don't use computer screen goes black and my mouse & keyboard light goes off, also I am playing video game with joystick and it goes black even then because I don't use keyboard and mouse I guess. It's like Power & Sleep settings are not working fine (Screen - When plugged in, turn off after setting is set to "NEVER" but it's not working for some reason. When I move mouse it goes back to normal, also when I am watching a movie screen is turning off. That didn't happen on windows 8.1 , my pc specs are great, it can't be a problem for sure.

I had sleep issues with 8.0. The system would go black when not in use, but after moving the mouse or pressing the keyboard, the system would not wake up. After a few updates, the system worked again.

I have only had major problems with security software so far in 10
(avast and comodo causing explorer, the start menu and app interface to stop working).

Try using your system in safe mode to see if you have the same problem.
