I would but windows keeps self installing its own driver and when i plug the arduino in, it comes up as USB Serial Port(COM5) instead of arduino mega or uno. so i just try update the driver to select the arduino driver folder and it says " The wizard could not find a better match for your hardware than the software you already have installed. "
but i have tried to write to the arduino with com 5 and this pops up.
Problem uploading to board. see http://www.arduino.cc/en/Guide/Troubleshooting#upload
Binary sketch size: 1584 bytes (of a 126976 byte maximum)
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
And this is with windows XP SP 3
with "Never search Windows Update for drivers. " under hardware of my computer
