Not able to upload sketch: avrdude: stk500_recv(): programmer is not responding

I've been trying to upload some code on my official Arduino Uno, but it doesn't seem to work. I've even tried to upload a blink but the same error persists. I'm using Windows 10 and I had never had any problem with this board.

The error code is this one:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xd6
avrdude: stk500_recv(): programmer is not responding

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0xd6

Another thing to remark is that regardless of the port I attatch my board to the port is always COM4. And also the reset button won't work.

Thanks in advance.
