Arduino Uno Clone is Frozen

(Translated with Google Translate, I Dont Speak English So Well)
Hello! I had bought an arduino a week ago, it worked fine, the next day. I connect it to my computer and I see that the ON LED is off, like a small light that is barely visible. and the integrated led is frozen.
The RX LED is off, just turn on a small light to know that it is transferring data

I thought it was a problem that I had uploaded a sketch with error, I uploaded the blink code. but it gives me this error

avrdude: stk500_recv (): programmer is not responding

It's very strange what happened to this arduino.

I already tried to change the USB port, and use three computers that I have in my home. But nothing happens. I have already test the voltages

Thanks for your help! :slight_smile:
