Marlin keeps restart when I push the screen button (3 replies)

Hi all. I am new here and also new for the 3d printers world. I have made a 3d printer by myself. everything seems ok but when I install marlin firmware I cant use the printer. while my printer is connected to my pover supply 12V 30A and when I push the button on the screen for selecting the menu items, marlin is restarting. But when I connect my computer with usb and power supply together, Its working fine

I am using Robotdyn arduino mega, robotdyn reprap, robotdyn DRV8825

When I install repetier there is no problem. It works fine

Any help will be highly appriciated.
