Having Trouble Uploading to Arduino UNO

Hello, At first my arduino UNO was uploading just fine until it began giving me this error.It began acting like this when I tried a simple code it did not work and give me the same error. I dont where where to go from here:

const int LED =13;
void setup() { pinMode(LED, OUTPUT);
}

void loop() {
  
digitalWrite(LED, HIGH);
delay(1000);
digitalWrite(LED, LOW);
delay(1000);  
}

Arduino: 1.6.9 (Windows 8.1), Board: "Arduino/Genuino Uno"

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

If you guys need to know what kind of board I have specifically , it this the one:
https://www.amazon.com/LANMU®-Atmega328p-Atmega16u2-Version-Arduino/dp/B00SF28U7A?ie=UTF8&Version=1&entries=0

I just want to know if its maybe the drivers or the ports or something.

What shows up in Windows Device Manager?

ieee488:

It says the port COM3 is plugged into the arduino

This is like pulling teeth. And is there an error?

Yes there is still an error.
It is the same error listed above.
