Keyboard + System BEEP

[3a5tw00D]

I play Counter-Strike and I've found that my computer's system speaker BEEPS whenever I hold 3 or more buttons at the same time ingame on my keyboard (and in Windows too), thus refusing to switch to that weapon in SLOT2 and just giving me a BEEP (SHIFT+W/S/X+2)
Of course this is with any keyboard (as I used to lead a BEEPING chorus in my computer classes, driving the teacher nuts ) but does anyone know how to fix this? I really tried lots of diff things, reinstalling logitech keyboard software with latest and uninstalling, turned off stickykeys, updated my bios and chipset, tryed a different keyboard. Anyone?

I dont think this is something you can 'fix'. Your computer can only take input from so many keys at once.
