Asking for urgent help

Please.. If there is any one can help me.. My arduino suddenly didn't connect to my pc.. And the device manager said that "windows has stopped this device because it has reported problems ".. And I tried to change the cable but it didn't work

If you have any external circuitry connected to the Arduino board, try removing it to see if the problem will go away.

If you don't have one of those nifty plastic bases, make sure the Arduino board is not sitting on any conductive objects that might short out the contacts on the bottom of the board.

Make sure the USB cable is fully plugged into the Arduino board and the computer.

Did all that already..
Does that mean my Arduino has burnt out?
