Movement problem (Counter-Strike: Global Offensive)

hello everyone, I didn’t find what I was looking for on the forum, can anyone help
after reinstalling it is visible from 10 to 10 in cs go there was a problem with movement, you press the walk button, any, whether it’s forward or left and the model takes 3 instead of one step as with to fight this?? I write on the Internet about lowering the priority level, I changed the usual high low does not help
