Still cant get it to boot

So I am stuck. After working out all the issues I had with the ISP header, I can burn the bootloader and firmware but the damn thing wont boot. All lights on, no pulses on the crystal. It is like there AVR is not even running. Changed crystals, changed AVRs, gone over the solder joints 10 times. Still nothing. Any input appreciated… I am powering it via +5 on my bench PSU
