Hello, I recently got a Pi with a large order I placed, a rev. 2 board. It was fine for ~2 weeks, but today it simply won't boot anymore, when I power it on, there's no SD activity. I tested the SD card in 2 other rev. 1 boards I have, and they both boot the card correctly and as expected. I have kept my Pi in a Pi Box that I made at my local hackerspace on the laser cutter, so it has been well protected. I also haven't hooked anything up to the GPIO pins, although I had been planning a project in the near future and that was my intent.
The only thing that I had done with this Pi was overclock it to the "medium" setting, which from my understanding, does not void the warranty.
Please advise me on what I should do.
P.S. The order # I got the Pi from is 200167.
