Those cap values are awfully small. What value does the crystal spec say you should have for load capaacitance? Take that value, double it, and subtract about 5 pf. Use that value for both caps and try again. [Non-text portions of this message have been removed]

AVR switchs on/off a 5V relay using ULN2003. The relay commands to 220V AC contactor, which finally runs motor pumps. All the circuits are placed in a metal box, and as far as I see, the spark from contactor coil disrupts LCD display or MCU itself. I used a serial RC in parallel
