Narrow it down by doing these things -

Connect another keyboard (known to be working normally) to your computer. If it works properly, that indicates that the new kb is defective. If the other keyboard behaves the same way as the new one, something's wrong with your computer.

Connect the new keyboard to another computer. If it still behaves strangely, that pretty much confirms that it is defective. If it works normally, that strongly indicates that there's something wrong with your computer.
