Your keyboard is not working on you system port. what you have to do this issue are of some reason it may be hardware or software to identify that either it is hardware or software what you have to do is plug your keyboard pin into a port and check what's happening. when you plugged your keyboard pin into your system port if the light is turn on then the it is not hardware problem. but if the light turn on and flash for a while then turn off then it is hardware problem. there are many data buses in keyboard cable. which is carrying data from keyboard to system. when any of the bus is out of working then it happen.what you have to do to solve the problem to repair your keyboard from an expert or get new keyboard for your system. i will recommend you to get new keyboard because the repaired keyboard show the same error after two three weeks and again a problem. so the new keyboard will be the best option. thanks

The motherboard would try to detect a keyboard when it POSTs and will give you an error message that it did not find one.

When you turn the computer on and try going to the BIOS (by pressing DELETE or ESC or F2 or what your computer's motherboard uses to get there), does it work? What about going to the advanced boot options through F8 or going to the boot menu F12?

If the problem is present using different keyboards on the same port, then the likely problem is the port itself. If you're using the PS/2 port for the keyboard connection, then you can try using a USB keyboard instead. But as it stands, your motherboard needs replacement if your keyboard port is not working.
