Hello
Did you test the motherboard? Are the necessary voltages for the motherboard present?
If all the voltages are present, first program the BIOS and replace parts such as RAM and CPU, and finally, you should look for problems on the ICs and chipsets on the motherboard.

Can u please post some voltages for us?
U can start by checking all the coils, check if u get any voltage on them when switching on and off.. also check for short on all coils.. and please post here. thanks
