Every once in a while my steering would lock up on me, making it hard to turn at times. I can't seem to figure out why. This happens with my PC hand held controller and it does the same thing when I use the keyboard. Can anyone help. NFSU2.

My specs:
Asrock P4, 2.0ghz motherboard
ATI AIW 7500 64mb video card/w catalyst drivers
Win XP Pro SP2
