When I try to upload the blink sketch to my arduino nano, the uploader freezes and after awhile gives me this message:

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
I've tried changing COM ports (COM1 now), updating drivers, and a different arduino nano board, but nothing has worked yet.
