Keyboard Not function

When i turn on my computer there is 1 long beep and 2 short ones, afterwards i get a message says that the keyboard isn't working, i go in a text message , try to write, no response...

How do i fix it?
What's the problem?
Please help

1 long followed by 2 short beeps is usually a graphics problem.

What model of computer and what OS are you running?
How is the keyboard and mouse plugged in?
Does the mouse work?

You can try plugging in a USB keyboard (and/or mouse) to any spare USB port on newer OS systems to be able to check the system further and see what might be wrong.

Hello,

I think first you have to change your keyboard after that if your problem as it is then you have to install the hardware driver software. It will remove the problem otherwise you have to format your system. The beep problem occurs due to not proper hardware installation.

I hope your problem will be solve by this method.

Thanks..
