my computer is freezing with arduino.


My computer with win xp is freezing when try to use my arduino

my computer has xp servipack 3

please help thanks.

Is it your whole computer that freezes or just the IDE? Does it freeze right after you upload a sketch? If so, please show the code that is uploaded that causes the freeze.

Usually freezing is due to the Arduino serial port blasting out data at high speed.
After you recover, ensure your sketch is not doing that.


the computer run very slow (almost freezing), this happens when I plug the arduino to the usb port.

The problem starts before upload the sketch.


Check for bluetooth activity also - that has been known to really bog down IDE performance.
