Cant upload code to Arduino anymore.

Hello!

I accidentally shorted my Arduino Uno yesterday when it was connected to my computer, and because of that my computer shut down. I booted the computer again and all the USB-ports seem to be fine, outputting power and recognizing my phone. The problem is that I can't upload code to my Arduino anymore. I have tried with two Unos and my Nano and none of them can receive the code. When I click on upload it uploads for a while but then I get this error message:

This report would have more information with

option enabled in File -> Preferences.

I have updated the drivers and reinstalled the IDE two times but without any luck. Any ideas?

You say you're trying to upload to an Uno, but you've selected a different board. And the output (out of sync errors with every resp= the same, and not 0) is consistent with attempting to upload with the wrong board selected....

With the board that I'm using that's the only thing that has worked before(from China). Here is the error message when I change it to UNO:

Build options changed, rebuilding all
