Question about Keyboards

Why certain combinations of keys doesn't work when pressed together? Sometimes there is also a beep.

While playing games, for example Tekken on a PC, I need to press 04 keys together for combos etc but it doesn't work.

I am wondering what could possibly be the issue and how do I solve it.

Thanks for help

Is this a laptop or desktop? What kind of keyboard are you using including the brand?

Perhaps try a joystick. or otherwise you may use the keys one after another with very small gap of time. i.e. instead of pressing 4, 8 and 6 just press 4 then quickly 8 and then 6. the taken combos will work absolutely right if you used the keys so fast that the gap is less than the games lag period and greater than the lag period of processor.
