Why is my samsung wireless mouse and keyboard not working?

I have the Samsung ATIV desktop computer which comes with wireless mouse and keyboard. These are connected to the computer by a USB. A few days ago the mouse and keyboard stopped working. I could still turn on the computer but the mouse would not show up on the screen and the keyboard did nothing. I tried reconnecting the devices to the computer but that would not work either. Then after i tried the mouse and keyboard on other computers and they work just fine. It is just the problem on that certain computer. Can somebody please help me out?
