Windows has stopped recognizing Arduino

Hi there,

My PC (windows 7) has stopped recognizing my arduino (uno) boards. When I connect the board, there's no port available in the Arduino IDE. Windows device manager shows an Arduino connected in LPT and COM ports. However, properties of the device show there's no driver installed. Updating the driver just dont work. Also, when i disconnect the Arduino, it keeps showing in the device manager, like some king of unfinished process.

I do not know what to do. I' ve tried to use other drivers. I also tried to uninstall the device from my PC, but nothing works.

It would be really nice if I can get some help.

Which other drivers have you tried ?

Are they using the CH340 drivers maybe ? (not included with the IDE)

You really need to supply some specific details or screen shots or error logs etc etc.

This has happened on multiple boards? Have you hooked up other hardware to all of these boards?
