keys on a keyboard

[Stern]

when playing vice city and i press W, S, and A or D at the same time to do a donut, my computer goes beep, beep, beep and only allows the first 2 pressed keys to go through. It works fine on my friends computer. He gave me his keyboard, and it still doesn't work
We have exactly the same motherboard, too

Turn off sticky keys - press shift 5 times, a screen will pop up along with a weird beep-like sound. You can turn it off from there.

they are disabled already

If it's any consolation, my crappy wireless Microsoft keyboard will only take 2 commands at once. Very annoying while playing games.

the problem doesn't seem to be the keyboard though, since we both have the same mobo, i tried it with the same keyboard on both computers

Is it PS/2 or USB?
