My sons desktop froze and the receiver for the wireless keyboard and mouse isn't working. I've tried reconnecting and synching the devices but it didn't work. I've installed new batteries on both keyboard and mouse and they are fine but the light on the receiver does not turn on. It is connected to a usb port in the computer. I've tried connecting it to a different usb port but still nothing. I also bought a new wireless keyboard combo but since I can't get into the computer to install it, It serves no purpose right now. Please Help!
