Arduino Uno still not working with new ATMEGA328P-PU

I have been having a problem with my Arduino Uno. After asking around, I was told I had to replace the ATMEGA328P-PU with a new one. I have no experience with boot-loaders, so I purchased the version here with the Uno boot-loader.

I installed the new ATMEGA328P-PU, however when trying to load a simple sketch onto my arduino I recieve the error message, “avrdude: stk500_getsync(): not in sync: resp=0x00”  What do I have to do to make the ardiuno software sync with your ATMEGA328P-PU.

Thanks

Chances are that the program on your ATMEGAxU2 has corrupted. As luck would happen we wrote a really extensive guide to fixing this problem.

Let me know if that doesn’t fix the issue.
