USB does not work, the ability to connect a PC via USB from the TX and RX?

My Arduino micro USB does not work, contacts are obviously CO. Arduino can be connected to PC via PIN RX and TX using USB?

Reinstall drivers. Does it list the Arduino in device manager when plugged in?

POWER LED lights even when connected to USB. Lit only when I bring to PIN + 5V GNG. USB I may be defective (at the bottom got mini scratch).

How can I upload to the Arduino software via the Arduino IDE. I do not want to buy because bluetooth. It can connect the PC to the Arduino IDE despite RX - TX involving to USB?

COM port much use really want.
