As has been mentioned the GPIO's on a Pi are 3.3 V and don't take
kindly to 5 V. I assumed that the 5 V supply was only fed to the 5 V
USB input or to the 5 V pins on the GPIO header. If you connected the
5 V to the LED, then reistor then to a GPIO you might have fried that
GPIO but with a 510 ohm resistor I find that unlikely.

Try running the LED Python script with no resistors/LEDs connected,
does the Pi still fall over? Change the script to use a different
GPIO, try again with no R's or LEDs, if that works repeat with R's
and LED's connected (to 3.3 V...).
