Hi, I just got my xps630i,  Q9550, 8G ram, GTX280, vista-64;

i got this problem where when i start the computer,  an msg of " USB2 cable not connected" msg came out even b4 it loads Vista, and says press F1 to continue, F2 to enter setup.  if i press F1 , it loads Vista and everything seems working alright (at least i didnt notice anything wrong) but everytime when i turn the computer on i ll need to press F1 at start up??

can anyone troubleshoot this for me? thank you very much!
