I've done some modifications based on different forums and was successful on burning a bootloader and uploading a sketch. Now, I've got the correct Atmega328P, installed on the same layout and I'm having this problem. | |

Now that you've mentioned it, I'm seeing a small arc (spark) on the AREF pin. What I've done is I'd lifted the pin out to disconnect it from AVCC and VCC, and soldered a 100nF cap to GND. What it did however is create a larger arc on the pin. | |
