Have recently dowloaded and started playing the demo of the new game GTR (which is awesome btw) but every now and then if i press certain key combinations repeatedly while driving (ie braking and changing gear) the pc speaker will beep which puts me off as i keep thinking its the cpu getting too hot (which it isnt). Why is this? is there any way of turning it off? i have noticed it in a few other games such as nfsu, but GTR needs more concentration than that so its more distracting here.
