for a while now my css would not work. When i tried to launch it nothing would happen then when i tried again it said another instance of the game was running. so i end tasked it and tried again with no luck. just this last steam update did it start working again but now i have some other problems which makes the game unplayable.

Heres a video to show you what happens. Basically i cant shoot, any shooting/attacking you see is done automaticly. When i switch weapons it starts shooting and i cant stop it, i cant reload, i cant throw nades either. All i can do is just switch weapons and watch it spray.

Iv tried reinstalling , defragging, restarting steam, and restarting computer.

any help is appreciated, thankyou
