Serial port not found? Answered

I tried to use my arduino today but COM3 couldn't be found. I tried it with older versions and other USB ports but it still didn't work. Anybody knows how to fix it?

Have you tried a different PC ?
Have you done something bad to the board ? Overvolted a pin ? Overcurrented a pin ?

When I took the circuit off the board it suddenly worked. I don't know what I did wrong, but the next time it happens I will look for any problem. Thanks anyway...

No but the ON led turns on for a few seconds and then off.
