USB communication OK, but no voltage??

Development Tools IDE 1.x

Hi everyone,

this morning using my arduino, I connected it to my PC with USB and it started, but after a few seconds stopped working and LEDS were off.

Now the Arduino doesnt start if only using USB.

If i use a extern Current (12v-Adapter or Vin pin) the Ardu starts properly and if I connect it now to the PC with USB, it works fine, no problems with serial communication.

What can be the problem??

Thanks in advance

Nop, it is not broken ;D . I tried it though. The Ardu doesnt start only with Usb in any other Computer also.
