Arduino Uno R3 by Elegoo Troubleshooting.

I recently ran into an issue with my arduino board where I am unable to upload code to the board. The progress bar fills up and then stops there for about a minute and then gives me a list of "avrdude: stk500_getsync(): not in sync: resp=0x00" errors. When I press the reset button, the LED's no longer blink. Any help is much appreciated.
