    Part of your problem may be a lack of current capacity of the 5V supply from your computer. The square black connector at the bottom of the picture of an Arduino UNO below is an external supply input. The Arduino specification is for 7-12V at this input. Have a look at the Arduino website for detailed information on power requirements.
