Answer #1
Time for a new keyboard maybe?
Answer #2
Are you using both – the keyboard and mouse connected to a USB hub? If so, then maybe it lacks power to operate both of them simultaneously. It happened with me!
Answer #3
Try to restart your PC and remove keyboard and mouse from your CPU, again put it. if facing same problem then try another keyboard.
Answer #4
