user11772: I have an Arduino Uno. The story is I installed Arduino IDE and Drivers before even buying an Arduino Board. I used it a little and when I bought and connected an arduino board, I was unable to make it detect. I smacked a little usimg google and was able to somehow Fix this. but again another day, It worked a little and started creatimg problems. now its not detecting. Please suggest me a way To make it work...
Should I format my windows 7 and Reinstall all the drivers as per rules?

user11676: under the IDE make sure you have set the correct board and comm port. go to tools>>board then choose your board then tools>>Comm to choose the correct comm port. 
is the IDE saying anything about having problems connecting to the board? 
and no re-installing all drivers should not be necessary.
