dfi NF4 ultra-d usb 2.0 :s

well i got this mobo in march and solved this problem at the time but i cant remember how.

i remember something about getting winxp SP1 but im running sp2 now but its not fixed it. making putting tracks on my mp3 player kinda sluggish.

i tried searching but coudnt find any other posts about this
