I used the same power supply just to make sure the conditions were the same. The board that is giving me the problem is right out of the anti-static bag, it's brand new. Unfortunately, I did not test the board before I soldered it, I made an assumption that it was just fine. This makes two boards in a row that have now died with some kind of problem, the first one lasted about a month before it died, some kind of Vpp error comes up, and now this one. Either I am having some very bad luck, or ... When I mentioned headers, that includes four apiece on the Vss, Vdd, and Vin. I will stop here, otherwise I will start sounding like a whiner.
