Hello! I bought an arduino last week and start doing experiments, it all worked well. But today when I plugged the arduino in the PC nothing happend. The PC is not "seeing" my arduino, I tried instalating and deinstaliting drivers and stuff, but the problem is that the PC doesn't see my arduino neither like a unknown device,it just ignores it. I have another one and that workes perfectly. I searched over the internet but I haven't found anything.
The board is not damaged, the cable is ok... please help me

I forgot to say that the power led on the arduino turns on. I tried another computer, the same problem

Update: I tried putting the firmware on the 16u2 but I have the following problems:
1.Arduino doesn't enter DFU mode so I can't use flip
2. Tried using another ardino as ISP but I get
Quote
avrdude: Device signature = 0xffffff
avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
this check

I checked the connections 10 times but all is ok. Avrdude recognizes the 328 but does not recognize the 16u2, please help me

The way you have it in your schematic isn't the same as how you have it wired up!
