Is this the famous? 2 USD keyboard? My thought is you need to take it as a lesson about cheap things and try another keyboard.

Just saying this out of necessity, sorry if you knew this already. Whenever you are connecting or disconnecting a PS/2 keyboard you need to turn off the computer first.

Check the pins in the keyboard connector, do they all look straight and undamaged?

Can you try it in a different computer? If so, are the same keys faulty?

If you are using a Windows operating system do you know how to uninstall the keyboard in devices or device manager? Uninstall the keyboard and then let Windows find it.

If none of the suggestions in this thread help can you return this keyboard?

OKay thanks for the advices guys, i ws able to return it.. so yes i hope ill learn from that thank you
