My mouse and keyboard have a problem?

I have a laptop, but i use a wirless external mouse and keyboard. When i play a game like minecraft, the controls mess up. When i use wsad, the mouse doesn't work, when i use the mouse, the wsad keys stop working, any help is appreciated!

I think its the driver, because the one that you have right now might be out of date or parcialy uncompatible to your devices, thats why sometimes it crashes.

Check out this driver, it worked awesome for me. http://gotlinks.co/3lm1

Check drives are the first guy said.
