I tryd connecting board to another computer and same thing happens. Does someone know What is wrong with my board?


Do you have anything connected to the board?

How do you connect the board to a power source? Which power source?

Your post seems to imply that you connect pc and power source at the same time; do you?
If you understand an example, use it.
If you don't understand an example, don't use it.
