I have tried 2 difference sources. Firstly a computer power supply's 5v rail, and ive also tried the 5v source on the pickit2. No regulator.

The blue is bottom layer - all surface mount components are on the bottom layer. The through-hole components are on the top layer. Even though it looks like components are on top of each other, they are actually on opposite sides of the board.

I realise that the PCB isn't self explanatory, sorry.
