Is system boots? Try to connect the USB keyboard and test entering the BIOS with it. If external keyboard is work, that means problem is in internal keyboard module, or software problem in the OS.

@kapitalizm thanks! After further trials, I've came to a conclusion; it is indeed a hardware problem,
