Today my keyboard is not working properly. I buy new keyboard and replace with previous. I attach new keyboard with my CPU. This is dell keyboard then I restart my system but it is not working proper. Then I go in device manager and check it. All drivers are installed also keyboard is showing in device manager. But it is not working any one tell me its reason.
By checking the wires from Central Processing Unit (CPU) to your keyboard does help fixing the problem.
Most problem with keyboard is the wire connects at the back. When connector is plugged in, it looks like that it's connected properly but it's not being recognized by the computer.
There are few ports at the back to use, try the other slots for keyboard connections. Hold it tight and wiggle a bit, observe if the light on the keyboard will lit up.
Consider adding up USB connector instead of using the standard keyboard's rounded or square holes. Re-start the computer and check the keyboard if it's working.

Hello Ronald,
The problem may be occurring because the USB ports on your computer are faulty are failing to work properly. From the image that you have pasted above, the drivers are alright, and the keyboard itself being brand new we cannot say that its cable is faulty assuming that you tasted it and ensured that it was working before you purchased it.
I will suggest that you try connecting the keyboard using alternative USB ports that you are sure that are working, for instance the one you are using for the mouse. Connect the keyboard to it and restart the computer, try using the keyboard, it should work. In that case you will have to replace the faulty USB ports on your computer.
