@arth take a look at your power board. Check the capacitors and the fuses with a multimeter. Post some images of your boards with your question so that we can see what you see. Use this guide Adding images to an existing question for that.

@arth sounds like a bad power board. Could be as simple as bad capacitors. You also want to go ahead and check this video to see if you have the proper voltages. Also check on here since the power board should be similar.
