Ok, now it's where i start to freak out LOL
I already connected the crystal load capacitors ground directly to arduino gnd instead of going through the switch.
I added decoupling capacitors, is it like that?

About ground plane/pour, i couldnt find anything that would make me understand what i need to do.
(i've attached fritzing project just in case someone has it installed and is willing to show me how it can be done)
thanks
