Can't Upload New Sketches to Uno

I have a fairly new Uno and I recently went to go an upload a new sketch and have been unsuccessful. So far form my research I think I have a corrupt boot loader or a fried chip.

This is the error I keep getting.

***failed; avrdude: verification error, first mismatch at byte 0x0000 0x3f != 0x00 avrdude: verification error; content mismatch

Any thoughts or suggestion would help.
