Arduino Uno

Hi I just got an Arduino UNO AND i am running it on XP i keep getting this error code avrdude: stk500_getsync(): not in sync: resp=0x00 avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51 What does this mean what do i do PS i already made sure that i picked UNO in the settings

There seems to be several reasons why you may be getting this error (the most common one of which you've already covered in setting the correct board type).

Rather than re-hacking some of the previous posts have you seen this one?

It seems to cover a wide range of issues relating to this problem.
