Honored Contributor --- Quote Start --- no bang, i just got it, tried it and it pretty much worked, restarted my computer and cant figure out what went wrong in 2 minutes. but im not so sure i was in the room the whole time. --- Quote End --- The external power supply could be bad. The LED might be on when there is no board attached because there is no load on it. You could try shorting a resistor across the terminals of your supply. Just make sure to calculate the resistor size correctly, eg., account for its power rating, and try not to exceed it by too much (since it'll get hot). If that causes the supply LED to go out, then you know that the supply is probably bad. (You can use multiple resistors in parallel to draw more current without exceeding the power rating of a single resistor). Cheers, Dave
