i am working on windows 7, 64 bit machine..my arduino was working fine till i connected a 12v adapter to power my motors but after that my arduino doesn't connect to the computer..i have tried re-installing ftdi vcp drivers..even re-installed arduino IDE
all other arduino works fine on my machine...
so i think the board has been damaged...is there anything i can do??

The OP's problem was after he connected 12V.

If you have a different problem, read the threads at the top of the forum, then post a new thread with a description of your problem, which Uno you have (a link to where you bought it from), what operating system, and what you have tried so far.

@chilliTronics
i pressed the reset button later so now i guess nothing is there..
i connected 12v to the power jack provided on the board..
