Device Failure

Hi guys! I have had an arduino rev3 for about a year now and got it to work once with the blink script. After that i have always gotten code 43 and nothing ive done has seemed to work. i have gone through all the steps on the forum and still theres nothing. I do have a theory that its because the arduino has "malfunctioned" but i have no clue how to fix it. i am running windows 7 64bit and if anyone has any insight i would more than appreciative.

Code 43 on Windows means that the device driver fails. Maybe this could help:
or google for more information.

Thanks I checked it out and tried to see it worked. Unfortunately I had little luck with that but thanks of was definitely worth a shot.

Is the Arduino visible in the device manager notwithstanding that not working properly?
