Arduino not recognised by the computer

I got my Elegoo UNO R3 about a month ago (so a refund is not an option) and used it for a while. It worked flawlessly. Today, when I plug it in it just doesn't get recognized by my pc (Windows 10 x64). I have tried literally everything: reinstall drivers, change the ATMega328p-U chip, clicking the Reset button, changing the cables but NOTHING worked for me!!! It won't be recognized by my computer!

Any help?

Have you tried another computer?

The last sketch that is on it does that still work?

Yes, I have tried my father's laptop with two different cables and both didn't work. I'm desperate. The code on the chip still works as intended
