Games not registering correct input from keyboard/mouse

[CisntSharp]

 

Sorry that this might be a bit lengthy
The problem im having is when ever i use my computer when i press left click it will work normal sometimes but most the time the button will press all the way down and go up normally clicking but the computer will think its still being press until i click again so in games like csgo it will keep shooting my gun until i left click again (annoying)  and with my keyboard  when i try bhop in csgo or click 2-3 keys at a time one of the keys doesn't work or respond so ill jump in csgo and press "a"/"d" to move left/right in air and it will make me go straight instead of glide left/right
I listed both of these issues in one because i believe its a related issue

Does this happen with every mouse and keyboard? Start by clearing all USB drivers. So going to device manager and removing all related to mouse/keyboard. Then update USB3 drivers for your mobo.
